PHP vs. Perl for XML

Hi, I've been trying to find information on the interaction of XML and PHP recently (for a view of one day writing .cgi scripts that search my xml documents with a knowledge of their hierarchy, etc.) And I came across this recorded roundtable discussion on perl and xml at: http://www.xml.com/lpt/a/av/revised.html Now, I wonder if Perl is a better choice than PHP to interact with XML Any experience on integrating PHP with XML? Santi PS: (The two main speakers are Larry Wall, the developer of the Perl programming language, and Tim Bray, the co-editor of the XML Specification and the technical editor for XML.com)
