Loading xml document and filter it with xpath

Question

Im using PHP to load a XML document:

$xmlDocument = file_get_contents($url, false, $context);
$xmlString = simplexml_load_string($xmlDocument);

XmlString and $url : http://testing.zwiink.us/getPurchased.php

Now im trying to filter out each element, which contains:

[u] => /zwinky/fds/creations/

I tried to use xpath, but always failed, i guess i used a wrong search value. Does anyone hava a idea how I would get this working?

You need to make an xpath query first with using contains() :

$xmlDocument = file_get_contents($url, false, $context);
$xmlString = simplexml_load_string($xmlDocument);

// target elements with that attribute
$u = $xmlString->xpath('//*[contains(@u, "/zwinky/fds/creations/")]');

echo '<pre>';
print_r($u);
