parseChannel

protected WireFeed parseChannel(Element rssRoot)

Parses the root element of an RSS document into a Channel bean.

It reads title, link and description and delegates to parseImage, parseItems and parseTextInput. This delegation always passes the root element of the RSS document as different RSS version may have this information in different parts of the XML tree (no assumptions made thanks to the specs variaty)

Parameters: rssRoot the root element of the RSS document to parse.
