[fw-general] Zend_Dom

[Jaggi]

I've been trying to use zend dom but i've been having some issues so was
wondering if someone could tell me if this was possible...

XML:

  <channel>
  .....
    <item>
      <title>Flu drugs 'unhelpful' in children</title>
      <description>Experts are questioning the policy of giving
      antiviral drugs to children for swine flu saying it may do
      more harm than good.</description>

This is taken off the bbc so i just grab the xml feed and then run it...
this is the PHP:

$dom = new Zend_Dom_Query();
$dom->setDocumentXml($xml);
$results = $dom->queryXpath( 'channel/item' );

this returns all the item elements which is correct. Now what i wish to do
is loop through those and run some xpath queries on that to get the
individual tags(e.g. category, title, link). Can't seem to figure this out
as if i loop through the results all i get is the string which i can't
navigate anymore.
