[thelist] php and xpath

[Tim Stickland]

There are two things that really drive me mad - regular expressions and
XPath expressions. This week it's XPath's turn...

I'm trying to parse an RSS feed using Xpath. Here's a simplified version of
the XML:

<rss>
  <channel>
    <title>feed name</title>
  <channel>
  <item>
    <category>Music</category>
    <category>Youth</category>
    <description>blah blah</description>
  </item>
  <item>
    <category>Transport</category>
    <category>Cars and Bikes</category>
    <category>Automotive</category>
  </item>
</rss>

What I want to be able to do is select all item nodes (and child nodes) that
contain a category node with a value of 'Transport'. How would I do that?
Something along the lines of:

//item[category=Transport]

Any help greatly appreciated...

Thanks
Tim
