# goquery - a little like that j-thing, only in Go
[![Build Status](https://github.com/PuerkitoBio/goquery/actions/workflows/test.yml/badge.svg?branch=master)](https://github.com/PuerkitoBio/goquery/actions)
[![Go Reference](https://pkg.go.dev/badge/github.com/PuerkitoBio/goquery.svg)](https://pkg.go.dev/github.com/PuerkitoBio/goquery)
[![Sourcegraph Badge](https://sourcegraph.com/github.com/PuerkitoBio/goquery/-/badge.svg)](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+ and is tested on Go1.7+.
$ 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.**
* **2021-10-25 (v1.8.0)** : Add `Render` function to render a `Selection` to an `io.Writer` (thanks [@anthonygedeon](https://github.com/anthonygedeon)).
* **2021-07-11 (v1.7.1)** : Update go.mod dependencies and add dependabot config (thanks [@jauderho](https://github.com/jauderho)).
* **2021-06-14 (v1.7.0)** : Add `Single` and `SingleMatcher` functions to optimize first-match selection (thanks [@gdollardollar](https://github.com/gdollardollar)).
* **2021-01-11 (v1.6.1)** : Fix panic when calling `{Prepend,Append,Set}Html` on a `Selection` that contains non-Element nodes.
* **2020-10-08 (v1.6.0)** : Parse html in context of the container node for all functions that deal with html strings (`AfterHtml`, `AppendHtml`, etc.). Thanks to [@thiemok][thiemok] and [@davidjwilkins][djw] for their work on this.
* **2020-02-04 (v1.5.1)** : Update module dependencies.
* **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 [doc][] 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 [package 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.
## Examples
See some tips and tricks in the [wiki][].
Adapted from example_test.go:
```Go
package main
import (
"fmt"
"log"
"net/http"
"github.com/PuerkitoBio/goquery"
)
func ExampleScrape() {
// Request the HTML page.
res, err := http.Get("http://metalsucks.net")
if err != nil {
log.Fatal(err)
}
defer res.Body.Close()
if res.StatusCode != 200 {
log.Fatalf("status code error: %d %s", res.StatusCode, res.Status)
}
// Load the HTML document
doc, err := goquery.NewDocumentFromReader(res.Body)
if err != nil {
log.Fatal(err)
}
// Find the review items
doc.Find(".left-content article .post-title").Each(func(i int, s *goquery.Selection) {
// For each item found, get the title
title := s.Find("a").Text()
fmt.Printf("Review %d: %s\n", i, title)
})
}
func main() {
ExampleScrape()
}

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.
* array.go : array-like positional manipulation of the selection.
- Eq()
- First()
- Get()
- Index...()
- Last()
- Slice()
* expand.go : methods that expand or augment the selection's set.
- Add...()
- AndSelf()
- Union(), which is an alias for AddSelection()
* filter.go : filtering methods, that reduce the selection's set.
- End()
- Filter...()
- Has...()
- Intersection(), which is an alias of FilterSelection()
- Not...()
* iteration.go : methods to loop over the selection's nodes.
- Each()
- EachWithBreak()
- Map()
* manipulation.go : methods for modifying the document
- After...()
- Append...()
- Before...()
- Clone()
- Empty()
- Prepend...()
- Remove...()
- ReplaceWith...()
- Unwrap()
- Wrap...()
- WrapAll...()
- WrapInner...()
* property.go : methods that inspect and get the node's properties values.
- Attr*(), RemoveAttr(), SetAttr()
- AddClass(), HasClass(), RemoveClass(), ToggleClass()
- Html()
- Length()
- Size(), which is an alias for Length()
- Text()
* query.go : methods that query, or reflect, a node's identity.
- Contains()
- Is...()
* traversal.go : methods to traverse the HTML document tree.
- Children...()
- Contents()
- Find...()
- Next...()
- Parent[s]...()
- Prev...()
- Siblings...()
* type.go : definition of the types exposed by goquery.
- Document
- Selection
- Matcher
* utilities.go : definition of helper functions (and not methods on a *Selection)
that are not part of jQuery, but are useful to goquery.
- NodeName
- OuterHtml

[![](https://travis-ci.org/andybalholm/cascadia.svg)](https://travis-ci.org/andybalholm/cascadia)
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.
[Refer to godoc here](https://godoc.org/github.com/andybalholm/cascadia).

# sid : generate sortable identifiers
## Overview
[![GoDoc](https://godoc.org/github.com/chilts/sid?status.svg)](https://godoc.org/github.com/chilts/sid)
[![Build Status](https://travis-ci.org/chilts/sid.svg?branch=master)](https://travis-ci.org/chilts/sid)
[![Code Climate](https://codeclimate.com/github/chilts/sid/badges/gpa.svg)](https://codeclimate.com/github/chilts/sid)
[![Go Report Card](https://goreportcard.com/badge/github.com/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.IdHex()
id3 := sid.IdBase32()
id4 := sid.IdBase64()
fmt.Printf("id1 = %s\n", id1)
fmt.Printf("id2 = %s\n", id2)
fmt.Printf("id3 = %s\n", id3)
fmt.Printf("id4 = %s\n", id4)
// -> "id1 = 1559872035903071353-1186579057231285506"
// -> "id2 = 15a5cf57e7d2a837-6eaafe687e7b3ec3"
// -> "id3 = 1b9efqnl51jj7-4u66ikpfq9ugm"
// -> "id4 = 1IeSBAWW9kK-0cDG64GQgGJ"

### Converts HTML into text of the markdown-flavored variety
## Introduction
Ensure your emails are readable by all!
Turns HTML into raw text, useful for sending fancy HTML emails with an equivalently nicely formatted TXT document as a fallback (e.g. for people who don't allow HTML emails or have other display issues).
html2text is a simple golang package for rendering HTML into plaintext.
There are still lots of improvements to be had, but FWIW this has worked fine for my [basic] HTML-2-text needs.
It requires go 1.x or newer ;)
## Download the package
```bash
go get jaytaylor.com/html2text
```
## Example usage
### Library
```go
package main
import (
"fmt"
"jaytaylor.com/html2text"
)
func main() {
inputHTML := `
<html>
<head>
<title>My Mega Service</title>
<link rel=\"stylesheet\" href=\"main.css\">
<style type=\"text/css\">body { color: #fff; }</style>
</head>
<body>
<div class="logo">
<a href="http://jaytaylor.com/"><img src="/logo-image.jpg" alt="Mega Service"/></a>
</div>
<h1>Welcome to your new account on my service!</h1>
<p>
Here is some more information:
<ul>
<li>Link 1: <a href="https://example.com">Example.com</a></li>
<li>Link 2: <a href="https://example2.com">Example2.com</a></li>
<li>Something else</li>
</ul>
</p>
<table>
<thead>
<tr><th>Header 1</th><th>Header 2</th></tr>
</thead>
<tfoot>
<tr><td>Footer 1</td><td>Footer 2</td></tr>
</tfoot>
<tbody>
<tr><td>Row 1 Col 1</td><td>Row 1 Col 2</td></tr>
<tr><td>Row 2 Col 1</td><td>Row 2 Col 2</td></tr>
</tbody>
</table>
</body>
</html>`
text, err := html2text.FromString(inputHTML, html2text.Options{PrettyTables: true})
if err != nil {
panic(err)
}
fmt.Println(text)
}
```
Output:
```

A high-performance 100% compatible drop-in replacement of "encoding/json"
# Benchmark
![benchmark](http://jsoniter.com/benchmarks/go-benchmark.png)
Source code: https://github.com/json-iterator/go-benchmark/blob/master/src/github.com/json-iterator/go-benchmark/benchmark_medium_payload_test.go
Raw Result (easyjson requires static code generation)
| | ns/op | allocation bytes | allocation times |
| --------------- | ----------- | ---------------- | ---------------- |
| std decode | 35510 ns/op | 1960 B/op | 99 allocs/op |
| easyjson decode | 8499 ns/op | 160 B/op | 4 allocs/op |
| jsoniter decode | 5623 ns/op | 160 B/op | 3 allocs/op |
| std encode | 2213 ns/op | 712 B/op | 5 allocs/op |
| easyjson encode | 883 ns/op | 576 B/op | 3 allocs/op |
| jsoniter encode | 837 ns/op | 384 B/op | 4 allocs/op |
Always benchmark with your own workload.
The result depends heavily on the data input.
# Usage
100% compatibility with standard lib
Replace
```go
import "encoding/json"
json.Marshal(&data)
```
with
```go
import jsoniter "github.com/json-iterator/go"
var json = jsoniter.ConfigCompatibleWithStandardLibrary
json.Marshal(&data)
```
Replace
```go
import "encoding/json"
json.Unmarshal(input, &data)
```
with
```go
import jsoniter "github.com/json-iterator/go"
var json = jsoniter.ConfigCompatibleWithStandardLibrary
json.Unmarshal(input, &data)
```
