使用PHP从XML中删除命名空间

I have an XML document that looks like this:

<Data 
  xmlns="http://www.domain.com/schema/data" 
  xmlns:dmd="http://www.domain.com/schema/data-metadata"
>
  <Something>...</Something>
</Data>

I am parsing the information using SimpleXML in PHP. I am dealing with arrays and I seem to be having a problem with the namespace.

My question is: How do I remove those namespaces? I read the data from an XML file.

Thank you!

    If you're using XPath then it's a limitation with XPath and not PHP look at this explanation on xpath and default namespaces for more info.

    More specifically its the xmlns="" attribute in the root node which is causing the problem. This means that you'll need to register the namespace then use a QName thereafter to refer to elements.

    $feed = simplexml_load_file('http://www.sitepoint.com/recent.rdf');
    $feed->registerXPathNamespace("a", "http://www.domain.com/schema/data");
    $result = $feed->xpath("a:Data/a:Something/...");
    

    Important: The URI used in the registerXPathNamespace call must be identical to the one that is used in the actual XML file.
