Combining XML Parsers
Once the parser gets through the XML tags describing the podcast feed as a whole, it gets into a series of <item> tags that describe individual episodes. If we think of the XML as a tree structure, the contents of each episode are one level down from the top-level metadata. Let’s look at what an episode item looks like in the XML (we’ve added some line breaks and omitted a huge block of HTML in the <description>tag to fit the book’s formatting):
| | <item> |
| | <title>Episode 1: The Pilot Episode</title> |
| | <pubDate>Tue, 27 May 2014 16:50:00 +0000</pubDate> |
