What are you using to pass the XML? Which PHP library?

[lonestar23]

I am using SimpleXML, but can use DOM if that is what your recommend.

I am able to parse xml namespaces but have problems parsing data from namespace attributes found in the above file. Would like to parse/ retrieve "CA" from Line 15 "<ac:localization ac:country="CA" ac:language="en">"

Thanks for help!
