 ## 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`.
+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 rss, atom and json 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` or `json.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.

 ![Diagram](docs/sequence.png)

-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.

 ## 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`.

-## Extensions 
+## 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 `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.
+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 arbitrary 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.
+
+## Overview
+
+To begin parsing a XML document using `goxpp` you must pass it an `io.Reader` object for your document:
+
+```go
+file, err := os.Open("path/file.xml")
+parser := xpp.NewXMLPullParser(file, false, charset.NewReader)
+```
+
+The `goxpp` library decodes documents into a series of token objects:
+
+| Token Name                       |
+|----------------------------------|
+| 	StartDocument                  |
+| 	EndDocument                    |
+| 	StartTag                       |
+| 	EndTag                         |
+| 	Text                           |
+| 	Comment                        |
+| 	ProcessingInstruction          |
+| 	Directive                      |
+| 	IgnorableWhitespace            |
+
+You will always start at the `StartDocument` token and can use the following functions to walk through a document:
+
+| Function Name                    | Description                           |
+|----------------------------------|---------------------------------------|
+| 	 Next()                        | Advance to the next `Text`, `StartTag`, `EndTag`, `EndDocument` token.<br>Note: skips `Comment`, `Directive` and `ProcessingInstruction` |
+| 	NextToken()                    | Advance to the next token regardless of type.                                                                |
+| 	NextText()                     | Advance to the next `Text` token.                                                                |
+| 	Skip()                         | Skip the next token.   |
+| 	DecodeElement(v interface{})   | Decode an entire element from the current tag into a struct.<br>Note: must be at a `StartTag` token |

+* concurrent.Map: backport sync.Map for go below 1.9
+* concurrent.Executor: goroutine with explicit ownership and cancellable
+
+# concurrent.Map
+
+because sync.Map is only available in go 1.9, we can use concurrent.Map to make code portable
+
+```go
+m := concurrent.NewMap()
+m.Store("hello", "world")
+elem, found := m.Load("hello")
+// elem will be "world"
+// found will be true
+```
+
+# concurrent.Executor
+
+```go
+executor := concurrent.NewUnboundedExecutor()
+executor.Go(func(ctx context.Context) {
+    everyMillisecond := time.NewTicker(time.Millisecond)
+    for {
+        select {
+        case <-ctx.Done():
+            fmt.Println("goroutine exited")
+            return
+        case <-everyMillisecond.C:
+            // do something
+        }
+    }
+})
+time.Sleep(time.Second)
+executor.StopAndWaitForever()
+fmt.Println("executor stopped")
+```
+
+attach goroutine to executor instance, so that we can
+
+* cancel it by stop the executor with Stop/StopAndWait/StopAndWaitForever
+* handle panic by callback: the default behavior will no longer crash your application
