Jeremy Johnstone has come up with a simple plist xml parser. The plist format is what iTunes (and some other application) uses for its library files.
Normally SimpleXML is enough to handle most XML parsing needs, but the plist XML format is just broken enough to make parsing it with SimpleXML virtually impossible. Since I hadn't played with XMLReader much, I thought it would be a good chance to give it a spin. For the anxious types, the code is available on github in my php_class_lib project, so dig right in.
His parser takes in the name of the file to fetch and a parser() method is called to do the actual work. The contents of the file are returned as an array (he includes a print_r() of that output too).
