How do I select all parenting items based on a given node's attribute in php's xPath?
- by bakkelun
I have an XML feed that looks something like this (excerpt):
<channel>
<title>Channel Name</title>
<link>Link to the channel</link>
<item>
<title>Heading 1</title>
<link>http://www.somelink.com?id=100</link>

<category domain="http://www.somelink.com/?category=4">Category 1</category>
</item>
<item>
<title>Heading 2</title>

That's the rough of it. I'm using this piece of PHP (excerpt):
$xml = simple_xml_load_file($xmlFile);
$xml->xpath($pattern);
Now I want to get all ITEM-nodes (with their children) based on that pesky "domain" attribute in the category node, but no matter what I try it does-not-work.
The closest I got was "//category[@domain= 'http://www.somelink.com/?category=4']"
The expression I tried gave me this result:
[0] => SimpleXMLElement Object
(
[@attributes] => Array
(
[domain] => http://www.somelink.com/?category=4
)
[0] => Category 1
[1] => SimpleXMLElement Object
(
[@attributes] => Array
(
[domain] => http://www.somelink.com/?category=4
)
[0] => Category 1
The expression should contain all childrens of the two items in the example, but as you can see only the info in the category node is present, I want all the item nodes.
Any help would be highly appreciated.
