# goquery - a little like that j-thing, only in Go
|
||||
[](http://travis-ci.org/PuerkitoBio/goquery) [](http://godoc.org/github.com/PuerkitoBio/goquery) [](https://sourcegraph.com/github.com/PuerkitoBio/goquery?badge)
|
||||
|
||||
goquery brings a syntax and a set of features similar to [jQuery][] to the [Go language][go]. It is based on Go's [net/html package][html] and the CSS Selector library [cascadia][]. Since the net/html parser returns nodes, and not a full-featured DOM tree, jQuery's stateful manipulation functions (like height(), css(), detach()) have been left off.
|
||||
|
||||
Also, because the net/html parser requires UTF-8 encoding, so does goquery: it is the caller's responsibility to ensure that the source document provides UTF-8 encoded HTML. See the [wiki][] for various options to do this.
|
||||
|
||||
Syntax-wise, it is as close as possible to jQuery, with the same function names when possible, and that warm and fuzzy chainable interface. jQuery being the ultra-popular library that it is, I felt that writing a similar HTML-manipulating library was better to follow its API than to start anew (in the same spirit as Go's `fmt` package), even though some of its methods are less than intuitive (looking at you, [index()][index]...).

## Installation
|
||||
|
||||
Please note that because of the net/html dependency, goquery requires Go1.1+.
|
||||
|
||||
$ go get github.com/PuerkitoBio/goquery
|
||||
|
||||
(optional) To run unit tests:
|
||||
|
||||
$ cd $GOPATH/src/github.com/PuerkitoBio/goquery
|
||||
$ go test
|
||||
|
||||
(optional) To run benchmarks (warning: it runs for a few minutes):
|
||||
|
||||
$ cd $GOPATH/src/github.com/PuerkitoBio/goquery
|
||||
$ go test -bench=".*"
|
||||
|
||||
## Changelog
|
||||
|
||||
**Note that goquery's API is now stable, and will not break.**
|
||||
|
||||
* **2018-11-15 (v1.5.0)** : Go module support (thanks @Zaba505).
|
||||
* **2018-06-07 (v1.4.1)** : Add `NewDocumentFromReader` examples.
|
||||
* **2018-03-24 (v1.4.0)** : Deprecate `NewDocument(url)` and `NewDocumentFromResponse(response)`.
|
||||
* **2018-01-28 (v1.3.0)** : Add `ToEnd` constant to `Slice` until the end of the selection (thanks to @davidjwilkins for raising the issue).
|
||||
* **2018-01-11 (v1.2.0)** : Add `AddBack*` and deprecate `AndSelf` (thanks to @davidjwilkins).
|
||||
* **2017-02-12 (v1.1.0)** : Add `SetHtml` and `SetText` (thanks to @glebtv).
|
||||
* **2016-12-29 (v1.0.2)** : Optimize allocations for `Selection.Text` (thanks to @radovskyb).
|
||||
* **2016-08-28 (v1.0.1)** : Optimize performance for large documents.
|
||||
* **2016-07-27 (v1.0.0)** : Tag version 1.0.0.
|
||||
* **2016-06-15** : Invalid selector strings internally compile to a `Matcher` implementation that never matches any node (instead of a panic). So for example, `doc.Find("~")` returns an empty `*Selection` object.
|
||||
* **2016-02-02** : Add `NodeName` utility function similar to the DOM's `nodeName` property. It returns the tag name of the first element in a selection, and other relevant values of non-element nodes (see godoc for details). Add `OuterHtml` utility function similar to the DOM's `outerHTML` property (named `OuterHtml` in small caps for consistency with the existing `Html` method on the `Selection`).
|
||||
* **2015-04-20** : Add `AttrOr` helper method to return the attribute's value or a default value if absent. Thanks to [piotrkowalczuk][piotr].
|
||||
* **2015-02-04** : Add more manipulation functions - Prepend* - thanks again to [Andrew Stone][thatguystone].
|
||||
* **2014-11-28** : Add more manipulation functions - ReplaceWith*, Wrap* and Unwrap - thanks again to [Andrew Stone][thatguystone].
|
||||
* **2014-11-07** : Add manipulation functions (thanks to [Andrew Stone][thatguystone]) and `*Matcher` functions, that receive compiled cascadia selectors instead of selector strings, thus avoiding potential panics thrown by goquery via `cascadia.MustCompile` calls. This results in better performance (selectors can be compiled once and reused) and more idiomatic error handling (you can handle cascadia's compilation errors, instead of recovering from panics, which had been bugging me for a long time). Note that the actual type expected is a `Matcher` interface, that `cascadia.Selector` implements. Other matcher implementations could be used.
|
||||
* **2014-11-06** : Change import paths of net/html to golang.org/x/net/html (see https://groups.google.com/forum/#!topic/golang-nuts/eD8dh3T9yyA). Make sure to update your code to use the new import path too when you call goquery with `html.Node`s.
|
||||
* **v0.3.2** : Add `NewDocumentFromReader()` (thanks jweir) which allows creating a goquery document from an io.Reader.
|
||||
* **v0.3.1** : Add `NewDocumentFromResponse()` (thanks assassingj) which allows creating a goquery document from an http response.
|
||||
* **v0.3.0** : Add `EachWithBreak()` which allows to break out of an `Each()` loop by returning false. This function was added instead of changing the existing `Each()` to avoid breaking compatibility.
|
||||
* **v0.2.1** : Make go-getable, now that [go.net/html is Go1.0-compatible][gonet] (thanks to @matrixik for pointing this out).
|
||||
* **v0.2.0** : Add support for negative indices in Slice(). **BREAKING CHANGE** `Document.Root` is removed, `Document` is now a `Selection` itself (a selection of one, the root element, just like `Document.Root` was before). Add jQuery's Closest() method.
|
||||
* **v0.1.1** : Add benchmarks to use as baseline for refactorings, refactor Next...() and Prev...() methods to use the new html package's linked list features (Next/PrevSibling, FirstChild). Good performance boost (40+% in some cases).
|
||||
* **v0.1.0** : Initial release.
|
||||
|
||||
## API
|
||||
|
||||
goquery exposes two structs, `Document` and `Selection`, and the `Matcher` interface. Unlike jQuery, which is loaded as part of a DOM document, and thus acts on its containing document, goquery doesn't know which HTML document to act upon. So it needs to be told, and that's what the `Document` type is for. It holds the root document node as the initial Selection value to manipulate.
|
||||
|
||||
jQuery often has many variants for the same function (no argument, a selector string argument, a jQuery object argument, a DOM element argument, ...). Instead of exposing the same features in goquery as a single method with variadic empty interface arguments, statically-typed signatures are used following this naming convention:
|
||||
|
||||
* When the jQuery equivalent can be called with no argument, it has the same name as jQuery for the no argument signature (e.g.: `Prev()`), and the version with a selector string argument is called `XxxFiltered()` (e.g.: `PrevFiltered()`)
|
||||
* When the jQuery equivalent **requires** one argument, the same name as jQuery is used for the selector string version (e.g.: `Is()`)
|
||||
* The signatures accepting a jQuery object as argument are defined in goquery as `XxxSelection()` and take a `*Selection` object as argument (e.g.: `FilterSelection()`)
|
||||
* The signatures accepting a DOM element as argument in jQuery are defined in goquery as `XxxNodes()` and take a variadic argument of type `*html.Node` (e.g.: `FilterNodes()`)
|
||||
* The signatures accepting a function as argument in jQuery are defined in goquery as `XxxFunction()` and take a function as argument (e.g.: `FilterFunction()`)
|
||||
* The goquery methods that can be called with a selector string have a corresponding version that take a `Matcher` interface and are defined as `XxxMatcher()` (e.g.: `IsMatcher()`)
|
||||
|
||||
Utility functions that are not in jQuery but are useful in Go are implemented as functions (that take a `*Selection` as parameter), to avoid a potential naming clash on the `*Selection`'s methods (reserved for jQuery-equivalent behaviour).
|
||||
|
||||
The complete [godoc reference documentation can be found here][doc].
|
||||
|
||||
Please note that Cascadia's selectors do not necessarily match all supported selectors of jQuery (Sizzle). See the [cascadia project][cascadia] for details. Invalid selector strings compile to a `Matcher` that fails to match any node. Behaviour of the various functions that take a selector string as argument follows from that fact, e.g. (where `~` is an invalid selector string):
|
||||
|
||||
* `Find("~")` returns an empty selection because the selector string doesn't match anything.
|
||||
* `Add("~")` returns a new selection that holds the same nodes as the original selection, because it didn't add any node (selector string didn't match anything).
|
||||
* `ParentsFiltered("~")` returns an empty selection because the selector string doesn't match anything.
|
||||
* `ParentsUntil("~")` returns all parents of the selection because the selector string didn't match any element to stop before the top element.

||||

/*
|
||||
Package goquery implements features similar to jQuery, including the chainable
|
||||
syntax, to manipulate and query an HTML document.
|
||||
|
||||
It brings a syntax and a set of features similar to jQuery to the Go language.
|
||||
It is based on Go's net/html package and the CSS Selector library cascadia.
|
||||
Since the net/html parser returns nodes, and not a full-featured DOM
|
||||
tree, jQuery's stateful manipulation functions (like height(), css(), detach())
|
||||
have been left off.
|
||||
|
||||
Also, because the net/html parser requires UTF-8 encoding, so does goquery: it is
|
||||
the caller's responsibility to ensure that the source document provides UTF-8 encoded HTML.
|
||||
See the repository's wiki for various options on how to do this.
|
||||
|
||||
Syntax-wise, it is as close as possible to jQuery, with the same method names when
|
||||
possible, and that warm and fuzzy chainable interface. jQuery being the
|
||||
ultra-popular library that it is, writing a similar HTML-manipulating
|
||||
library was better to follow its API than to start anew (in the same spirit as
|
||||
Go's fmt package), even though some of its methods are less than intuitive (looking
|
||||
at you, index()...).
|
||||
|
||||
It is hosted on GitHub, along with additional documentation in the README.md
|
||||
file: https://github.com/puerkitobio/goquery
|
||||
|
||||
Please note that because of the net/html dependency, goquery requires Go1.1+.
|
||||
|
||||
The various methods are split into files based on the category of behavior.
|
||||
The three dots (...) indicate that various "overloads" are available.
|
||||

The Cascadia package implements CSS selectors for use with the parse trees produced by the html package.
|
||||
|
||||
To test CSS selectors without writing Go code, check out [cascadia](https://github.com/suntong/cascadia) the command line tool, a thin wrapper around this package.

# sid : generate sortable identifiers
|
||||
|
||||
## Overview
|
||||
|
||||
[](https://godoc.org/github.com/chilts/sid)
|
||||
[](https://travis-ci.org/chilts/sid)
|
||||
[](https://codeclimate.com/github/chilts/sid)
|
||||
[](https://goreportcard.com/report/github.com/chilts/sid)
|
||||
|
||||
This package is simple and only provides one function. The aim here is not pure speed, it is for an easy use-case
|
||||
without having to worry about goroutines and locking.
|
||||
|
||||
## Install
|
||||
|
||||
```
|
||||
go get github.com/chilts/sid
|
||||
```
|
||||
|
||||
## Example
|
||||
|
||||
```
|
||||
id1 := sid.Id()
|
||||
id2 := sid.Id()
|
||||
|
||||
fmt.Printf("id1 = %s\n", id1)
|
||||
fmt.Printf("id2 = %s\n", id2)
|
||||
|
||||
// -> "id1 = 1IeSBAWW83j-2wgJ4PUtlAr"
|
||||
// -> "id2 = 1IeSBAWW9kK-0cDG64GQgGJ"
|
||||
```

The `gofeed` library is a robust feed parser that supports parsing both [RSS](https://en.wikipedia.org/wiki/RSS) and [Atom](https://en.wikipedia.org/wiki/Atom_(standard)) feeds. The library provides a universal `gofeed.Parser` that will parse and convert all feed types into a hybrid `gofeed.Feed` model. You also have the option of utilizing the feed specific `atom.Parser` or `rss.Parser` parsers which generate `atom.Feed` and `rss.Feed` respectively.

## Features
|
||||
|
||||
#### Supported feed types:
|
||||
* RSS 0.90
|
||||
* Netscape RSS 0.91
|
||||
* Userland RSS 0.91
|
||||
* RSS 0.92
|
||||
* RSS 0.93
|
||||
* RSS 0.94
|
||||
* RSS 1.0
|
||||
* RSS 2.0
|
||||
* Atom 0.3
|
||||
* Atom 1.0
|
||||
|
||||
#### Extension Support
|
||||
|
||||
The `gofeed` library provides support for parsing several popular predefined extensions into ready-made structs, including [Dublin Core](http://dublincore.org/documents/dces/) and [Apple’s iTunes](https://help.apple.com/itc/podcasts_connect/#/itcb54353390).
|
||||
|
||||
It parses all other feed extensions in a generic way (see the [Extensions](#extensions) section for more details).
|
||||
|
||||
#### Invalid Feeds
|
||||
|
||||
A best-effort attempt is made at parsing broken and invalid XML feeds. Currently, `gofeed` can succesfully parse feeds with the following issues:
|
||||
- Unescaped/Naked Markup in feed elements
|
||||
- Undeclared namespace prefixes
|
||||
- Missing closing tags on certain elements
|
||||
- Illegal tags within feed elements without namespace prefixes
|
||||
- Missing "required" elements as specified by the respective feed specs.
|
||||
- Incorrect date formats
|
||||
|
||||
## Overview
|
||||
|
||||
The `gofeed` library is comprised of a universal feed parser and several feed specific parsers. Which one you choose depends entirely on your usecase. If you will be handling both rss and atom feeds then it makes sense to use the `gofeed.Parser`. If you know ahead of time that you will only be parsing one feed type then it would make sense to use `rss.Parser` or `atom.Parser`.
|
||||
|
||||
#### Universal Feed Parser
|
||||
|
||||
The universal `gofeed.Parser` works in 3 stages: detection, parsing and translation. It first detects the feed type that it is currently parsing. Then it uses a feed specific parser to parse the feed into its true representation which will be either a `rss.Feed` or `atom.Feed`. These models cover every field possible for their respective feed types. Finally, they are *translated* into a `gofeed.Feed` model that is a hybrid of both feed types. Performing the universal feed parsing in these 3 stages allows for more flexibility and keeps the code base more maintainable by separating RSS and Atom parsing into seperate packages.
|
||||
|
||||
|
||||
|
||||
The translation step is done by anything which adheres to the `gofeed.Translator` interface. The `DefaultRSSTranslator` and `DefaultAtomTranslator` are used behind the scenes when you use the `gofeed.Parser` with its default settings. You can see how they translate fields from ```atom.Feed``` or ```rss.Feed``` to the universal ```gofeed.Feed``` struct in the [Default Mappings](#default-mappings) section. However, should you disagree with the way certain fields are translated you can easily supply your own `gofeed.Translator` and override this behavior. See the [Advanced Usage](#advanced-usage) section for an example how to do this.
|
||||
|
||||
#### Feed Specific Parsers
|
||||
|
||||
The `gofeed` library provides two feed specific parsers: `atom.Parser` and `rss.Parser`. If the hybrid `gofeed.Feed` model that the universal `gofeed.Parser` produces does not contain a field from the `atom.Feed` or `rss.Feed` model that you require, it might be beneficial to use the feed specific parsers. When using the `atom.Parser` or `rss.Parser` directly, you can access all of fields found in the `atom.Feed` and `rss.Feed` models. It is also marginally faster because you are able to skip the translation step.
|
||||
|
||||
## Basic Usage
|
||||
|
||||
#### Universal Feed Parser
|
||||
|
||||
The most common usage scenario will be to use ```gofeed.Parser``` to parse an arbitrary RSS or Atom feed into the hybrid ```gofeed.Feed``` model. This hybrid model allows you to treat RSS and Atom feeds the same.
|
||||
|
||||
##### Parse a feed from an URL:
|
||||
|
||||
```go
|
||||
fp := gofeed.NewParser()
|
||||
feed, _ := fp.ParseURL("http://feeds.twit.tv/twit.xml")
|
||||
fmt.Println(feed.Title)
|
||||
```
|
||||
|
||||
##### Parse a feed from a string:
|
||||
|
||||
```go
|
||||
feedData := `<rss version="2.0">
|
||||
<channel>
|
||||
<title>Sample Feed</title>
|
||||
</channel>
|
||||
</rss>`
|
||||
fp := gofeed.NewParser()
|
||||
feed, _ := fp.ParseString(feedData)
|
||||
fmt.Println(feed.Title)
|
||||
```
|
||||
|
||||
##### Parse a feed from an io.Reader:
|
||||
|
||||
```go
|
||||
file, _ := os.Open("/path/to/a/file.xml")
|
||||
defer file.Close()
|
||||
fp := gofeed.NewParser()
|
||||
feed, _ := fp.Parse(file)
|
||||
fmt.Println(feed.Title)
|
||||
```
|
||||
|
||||
#### Feed Specific Parsers
|
||||
|
||||
You can easily use the `rss.Parser` and `atom.Parser` directly if you have a usage scenario that requires it:
|
||||
|
||||
##### Parse a RSS feed into a `rss.Feed`
|
||||
|
||||
```go
|
||||
feedData := `<rss version="2.0">
|
||||
<channel>
|
||||
<webMaster>example@site.com (Example Name)</webMaster>
|
||||
</channel>
|
||||
</rss>`
|
||||
fp := rss.Parser{}
|
||||
rssFeed, _ := fp.Parse(strings.NewReader(feedData))
|
||||
fmt.Println(rssFeed.WebMaster)
|
||||
```
|
||||
|
||||
##### Parse an Atom feed into a `atom.Feed`
|
||||
|
||||
```go
|
||||
feedData := `<feed xmlns="http://www.w3.org/2005/Atom">
|
||||
<subtitle>Example Atom</subtitle>
|
||||
</feed>`
|
||||
fp := atom.Parser{}
|
||||
atomFeed, _ := fp.Parse(strings.NewReader(feedData))
|
||||
fmt.Println(atomFeed.Subtitle)
|
||||
```
|
||||
|
||||
## Advanced Usage
|
||||
|
||||
##### Parse a feed while using a custom translator
|
||||
|
||||
The mappings and precedence order that are outlined in the [Default Mappings](#default-mappings) section are provided by the following two structs: `DefaultRSSTranslator` and `DefaultAtomTranslator`. If you have fields that you think should have a different precedence, or if you want to make a translator that is aware of an unsupported extension you can do this by specifying your own RSS or Atom translator when using the `gofeed.Parser`.
|
||||
|
||||
Here is a simple example of creating a custom `Translator` that makes the `/rss/channel/itunes:author` field have a higher precedence than the `/rss/channel/managingEditor` field in RSS feeds. We will wrap the existing `DefaultRSSTranslator` since we only want to change the behavior for a single field.
|
||||
|
||||
First we must define a custom translator:
|
||||
|
||||
```go
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
|
||||
"github.com/mmcdole/gofeed"
|
||||
"github.com/mmcdole/gofeed/rss"
|
||||
)
|
||||
|
||||
type MyCustomTranslator struct {
|
||||
defaultTranslator *gofeed.DefaultRSSTranslator
|
||||
}
|
||||
|
||||
func NewMyCustomTranslator() *MyCustomTranslator {
|
||||
t := &MyCustomTranslator{}
|
||||
|
||||
// We create a DefaultRSSTranslator internally so we can wrap its Translate
|
||||
// call since we only want to modify the precedence for a single field.
|
||||
t.defaultTranslator = &gofeed.DefaultRSSTranslator{}
|
||||
return t
|
||||
}
|
||||
|
||||
func (ct* MyCustomTranslator) Translate(feed interface{}) (*gofeed.Feed, error) {
|
||||
rss, found := feed.(*rss.Feed)
|
||||
if !found {
|
||||
return nil, fmt.Errorf("Feed did not match expected type of *rss.Feed")
|
||||
}
|
||||
|
||||
f, err := ct.defaultTranslator.Translate(rss)
|
||||
if err != nil {
|
||||
return nil, err
|
||||
}
|
||||
|
||||
if rss.ITunesExt != nil && rss.ITunesExt.Author != "" {
|
||||
f.Author = rss.ITunesExt.Author
|
||||
} else {
|
||||
f.Author = rss.ManagingEditor
|
||||
}
|
||||
return f
|
||||
}
|
||||
```
|
||||
|
||||
Next you must configure your `gofeed.Parser` to utilize the new `gofeed.Translator`:
|
||||
|
||||
```go
|
||||
feedData := `<rss version="2.0">
|
||||
<channel>
|
||||
<managingEditor>Ender Wiggin</managingEditor>
|
||||
<itunes:author>Valentine Wiggin</itunes:author>
|
||||
</channel>
|
||||
</rss>`
|
||||
|
||||
fp := gofeed.NewParser()
|
||||
fp.RSSTranslator = NewMyCustomTranslator()
|
||||
feed, _ := fp.ParseString(feedData)
|
||||
fmt.Println(feed.Author) // Valentine Wiggin
|
||||
```
|
||||
|
||||
## Extensions
|
||||
|
||||
Every element which does not belong to the feed's default namespace is considered an extension by `gofeed`. These are parsed and stored in a tree-like structure located at `Feed.Extensions` and `Item.Extensions`. These fields should allow you to access and read any custom extension elements.
|
||||
|
||||
In addition to the generic handling of extensions, `gofeed` also has built in support for parsing certain popular extensions into their own structs for convenience. It currently supports the [Dublin Core](http://dublincore.org/documents/dces/) and [Apple iTunes](https://help.apple.com/itc/podcasts_connect/#/itcb54353390) extensions which you can access at `Feed.ItunesExt`, `feed.DublinCoreExt` and `Item.ITunesExt` and `Item.DublinCoreExt`
|
||||
|

|
||||
|
||||
The ```DefaultRSSTranslator``` and the ```DefaultAtomTranslator``` map the following ```rss.Feed``` and ```atom.Feed``` fields to their respective ```gofeed.Feed``` fields. They are listed in order of precedence (highest to lowest):

The `goxpp` library is an XML parser library that is loosely based on the [Java XMLPullParser](http://www.xmlpull.org/v1/download/unpacked/doc/quick_intro.html). This library allows you to easily parse arbitary XML content using a pull parser. You can think of `goxpp` as a lightweight wrapper around Go's XML `Decoder` that provides a set of functions that make it easier to parse XML content than using the raw decoder itself.

/*
|
||||
Package html implements an HTML5-compliant tokenizer and parser.
|
||||
|
||||
Tokenization is done by creating a Tokenizer for an io.Reader r. It is the
|
||||
caller's responsibility to ensure that r provides UTF-8 encoded HTML.
|
||||
|
||||
z := html.NewTokenizer(r)
|
||||
|
||||
Given a Tokenizer z, the HTML is tokenized by repeatedly calling z.Next(),
|
||||
which parses the next token and returns its type, or an error:
|
||||
|
||||
for {
|
||||
tt := z.Next()
|
||||
if tt == html.ErrorToken {
|
||||
// ...
|
||||
return ...
|
||||
}
|
||||
// Process the current token.
|
||||
}
|
||||
|
||||
There are two APIs for retrieving the current token. The high-level API is to
|
||||
call Token; the low-level API is to call Text or TagName / TagAttr. Both APIs
|
||||
allow optionally calling Raw after Next but before Token, Text, TagName, or
|
||||
TagAttr. In EBNF notation, the valid call sequence per token is:
|
||||
|
||||
Next {Raw} [ Token | Text | TagName {TagAttr} ]
|
||||
|
||||
Token returns an independent data structure that completely describes a token.
|
||||
Entities (such as "<") are unescaped, tag names and attribute keys are
|
||||
lower-cased, and attributes are collected into a []Attribute. For example:
|
||||
|
||||
for {

The low-level API performs fewer allocations and copies, but the contents of
|
||||
the []byte values returned by Text, TagName and TagAttr may change on the next
|
||||
call to Next. For example, to extract an HTML page's anchor text:
|
||||
|
||||
depth := 0
|
||||
for {
|
||||
tt := z.Next()
|
||||
switch tt {
|
||||
case html.ErrorToken:
|
||||
return z.Err()
|
||||
case html.TextToken:
|
||||
if depth > 0 {
|
||||
// emitBytes should copy the []byte it receives,
|
||||
// if it doesn't process it immediately.
|
||||
emitBytes(z.Text())
|
||||
}
|
||||
case html.StartTagToken, html.EndTagToken:
|
||||
tn, _ := z.TagName()
|
||||
if len(tn) == 1 && tn[0] == 'a' {
|
||||
if tt == html.StartTagToken {
|
||||
depth++
|
||||
} else {
|
||||
depth--
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
Parsing is done by calling Parse with an io.Reader, which returns the root of
|
||||
the parse tree (the document element) as a *Node. It is the caller's
|
||||
responsibility to ensure that the Reader provides UTF-8 encoded HTML. For
|
||||
example, to process each anchor node in depth-first order:
|
||||
|
||||
doc, err := html.Parse(r)
|
||||
if err != nil {
|
||||
// ...
|
||||
}
|
||||
var f func(*html.Node)
|
||||
f = func(n *html.Node) {
|
||||
if n.Type == html.ElementNode && n.Data == "a" {
|
||||
// Do something with n...
|
||||
}
|
||||
for c := n.FirstChild; c != nil; c = c.NextSibling {
|
||||
f(c)
|
||||
}
|
||||
}
|
||||
f(doc)
|
||||

// Rendering is done on a 'best effort' basis: calling Parse on the output of
|
||||
// Render will always result in something similar to the original tree, but it
|
||||
// is not necessarily an exact clone unless the original tree was 'well-formed'.
|
||||
// 'Well-formed' is not easily specified; the HTML5 specification is
|
||||
// complicated.
|
||||
//
|
||||
// Calling Parse on arbitrary input typically results in a 'well-formed' parse
|
||||
// tree. However, it is possible for Parse to yield a 'badly-formed' parse tree.
|
||||
// For example, in a 'well-formed' parse tree, no <a> element is a child of
|
||||
// another <a> element: parsing "<a><a>" results in two sibling elements.
|
||||
// Similarly, in a 'well-formed' parse tree, no <a> element is a child of a
|
||||
// <table> element: parsing "<p><table><a>" results in a <p> with two sibling
|
||||
// children; the <a> is reparented to the <table>'s parent. However, calling
|
||||
// Parse on "<a><table><a>" does not return an error, but the result has an <a>
|
||||
// element with an <a> child, and is therefore not 'well-formed'.
|
||||
//
|
||||
// Programmatically constructed trees are typically also 'well-formed', but it
|
||||
// is possible to construct a tree that looks innocuous but, when rendered and
|
||||
// re-parsed, results in a different tree. A simple example is that a solitary
|
||||
// text node would become a tree containing <html>, <head> and <body> elements.
|
||||
// Another example is that the programmatic equivalent of "a<head>b</head>c"
|
||||
// becomes "<html><head><head/><body>abc</body></html>".

|

// Matching preferred against supported languages
|

//
|

// A Matcher for an application that supports English, Australian English,
|
||||
// Danish, and standard Mandarin can be created as follows:
|
||||
//
|
||||
// var matcher = language.NewMatcher([]language.Tag{
|
||||
// language.English, // The first language is used as fallback.
|
||||
// language.MustParse("en-AU"),
|
||||
// language.Danish,
|
||||
// language.Chinese,
|
||||
// })
|
||||
//
|
||||
// This list of supported languages is typically implied by the languages for
|
||||
// which there exists translations of the user interface.
|
||||
//
|
||||
// User-preferred languages usually come as a comma-separated list of BCP 47
|
||||
// language tags.
|
||||
// The MatchString finds best matches for such strings:
|
||||
//
|
||||
// handler(w http.ResponseWriter, r *http.Request) {
|
||||
// lang, _ := r.Cookie("lang")
|
||||
// accept := r.Header.Get("Accept-Language")
|
||||
// tag, _ := language.MatchStrings(matcher, lang.String(), accept)
|
||||
//
|
||||
// // tag should now be used for the initialization of any
|
||||
// // locale-specific service.
|
||||
// }
|
||||
//
|
||||
// The Matcher's Match method can be used to match Tags directly.
|
||||
//
|
||||
// Matchers are aware of the intricacies of equivalence between languages, such
|
||||
// as deprecated subtags, legacy tags, macro languages, mutual
|
||||
// intelligibility between scripts and languages, and transparently passing
|
||||
// BCP 47 user configuration.
|
||||
// For instance, it will know that a reader of Bokmål Danish can read Norwegian
|
||||
// and will know that Cantonese ("yue") is a good match for "zh-HK".
|
||||
//
|
||||
//
|
||||
// Using match results
|
||||
//
|
||||
// To guarantee a consistent user experience to the user it is important to
|
||||
// use the same language tag for the selection of any locale-specific services.
|
||||
// For example, it is utterly confusing to substitute spelled-out numbers
|
||||
// or dates in one language in text of another language.
|
||||
// More subtly confusing is using the wrong sorting order or casing
|
||||
// algorithm for a certain language.
|
||||
//
|
||||
// All the packages in x/text that provide locale-specific services
|
||||
// (e.g. collate, cases) should be initialized with the tag that was
|
||||
// obtained at the start of an interaction with the user.
|
||||
//
|
||||
// Note that Tag that is returned by Match and MatchString may differ from any
|
||||
// of the supported languages, as it may contain carried over settings from
|
||||
// the user tags.
|
||||
// This may be inconvenient when your application has some additional
|
||||
// locale-specific data for your supported languages.
|
||||
// Match and MatchString both return the index of the matched supported tag
|
||||
// to simplify associating such data with the matched tag.
|
||||
//
|
||||
//
|
||||
// Canonicalization
|
||||
//
|
||||
// If one uses the Matcher to compare languages one does not need to
|
||||
// worry about canonicalization.
|
||||
//
|
||||
// The meaning of a Tag varies per application. The language package
|
||||
// therefore delays canonicalization and preserves information as much
|
||||
// as possible. The Matcher, however, will always take into account that
|
||||
// two different tags may represent the same language.
|
||||
//
|
||||
// By default, only legacy and deprecated tags are converted into their
|
||||
// canonical equivalent. All other information is preserved. This approach makes
|
||||
// the confidence scores more accurate and allows matchers to distinguish
|
||||
// between variants that are otherwise lost.
|
||||
//
|
||||
// As a consequence, two tags that should be treated as identical according to
|
||||
// BCP 47 or CLDR, like "en-Latn" and "en", will be represented differently. The
|
||||
// Matcher handles such distinctions, though, and is aware of the
|
||||
// equivalence relations. The CanonType type can be used to alter the

// canonicalization form.
