The gofeed library is a robust feed parser that supports parsing both RSS and Atom 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.

Table of Contents


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 and Apple’s iTunes.

It parses all other feed extensions in a generic way (see the 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


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 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 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:
fp := gofeed.NewParser()
feed, _ := fp.ParseURL("")
Parse a feed from a string:
feedData := `<rss version="2.0">
<title>Sample Feed</title>
fp := gofeed.NewParser()
feed, _ := fp.ParseString(feedData)
Parse a feed from an io.Reader:
file, _ := os.Open("/path/to/a/file.xml")
defer file.Close()
fp := gofeed.NewParser()
feed, _ := fp.Parse(file)
Parse a feed from an URL with a 60s timeout:
ctx, cancel := context.WithTimeout(context.Background(), 60*time.Second)
defer cancel()
fp := gofeed.NewParser()
feed, _ := fp.ParseURLWithContext("", ctx)

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
feedData := `<rss version="2.0">
<webMaster> (Example Name)</webMaster>
fp := rss.Parser{}
rssFeed, _ := fp.Parse(strings.NewReader(feedData))
Parse an Atom feed into a atom.Feed
feedData := `<feed xmlns="">
<subtitle>Example Atom</subtitle>
fp := atom.Parser{}
atomFeed, _ := fp.Parse(strings.NewReader(feedData))

Advanced Usage

Parse a feed while using a custom translator

The mappings and precedence order that are outlined in the 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:

import (


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:

feedData := `<rss version="2.0">
<managingEditor>Ender Wiggin</managingEditor>
<itunes:author>Valentine Wiggin</itunes:author>
fp := gofeed.NewParser()
fp.RSSTranslator = NewMyCustomTranslator()
feed, _ := fp.ParseString(feedData)
fmt.Println(feed.Author) // Valentine Wiggin


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 and Apple iTunes extensions which you can access at Feed.ItunesExt, feed.DublinCoreExt and Item.ITunesExt and Item.DublinCoreExt

Default Mappings

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):
