Overview
syndfeed is a Go library for RSS 2.0 and Atom 1.0 feeds, supported implement extension module to parse any RSS and Atom extension element.
Dependencies
Getting Started
Parse a feed from URL
feed, _ := syndfeed.LoadURL("https://cn.engadget.com/rss.xml")
fmt.Println(feed.Title)
Parse a feed from io.Reade
feedData := `<rss version="2.0">
<channel>
<title>Sample Feed</title>
</channel>
</rss>`
feed, _ := syndfeed.Parse(strings.NewReader(feedData))
fmt.Println(feed.Title)
Parse an Atom feed into syndfeed.Feed
feedData := `<feed xmlns="http://www.w3.org/2005/Atom">
<title>Example Atom</title>
</feed>`
feed, _ := syndfeed.ParseAtom(strings.NewReader(feedData))
fmt.Println(feed.Title)
Parse a RSS feed into syndfeed.Feed
feedData := `<rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/">
<channel>
<dc:creator>[email protected] (Example Name)</dc:creator>
</channel>`
feed, _ := syndfeed.ParseRSS(strings.NewReader(feedData))
fmt.Println(feed.Authors[0].Name)
Extension Modules
In some syndication feeds, they have some valid XML elements but are not specified in either the Atom 1.0 or RSS 2.0 specifications. You can add extension module to process these elements.
The syndfeed build-in supported following modules: Dublin Core, Content, Syndication.
You can implement your own modules to parse any extension element like: iTunes RSS, Media RSS.
iTunes Module
iTunesHandler := func(n *xmlquery.Node, v interface{}) {
item := v.(*syndfeed.Item)
switch n.Data {
case "artist":
item.Authors = append(item.Authors, &syndfeed.Person{Name: n.InnerText()})
case "releaseDate":
item.PublishDate = ParseDate(n.InnerText())
}
}
// Register a new module to the syndfeed module list.
syndfeed.RegisterExtensionModule("https://rss.itunes.apple.com", syndfeed.ModuleHandlerFunc(iTunesHandler))
// Now can parse iTunes feed.
feed, err := syndfeed.LoadURL("https://github.com/zhengchun/syndfeed/blob/master/_samples/itunes.atom")
fmt.Println(feed.Items[0].Authors[0].Name)
// Output author name.
TODO
- Add RSS/Atom format output.
