Well, typically, when you're dealing with XML data and you want to transform that into HTML (for example), the "right way" is to use XSL. XSL is a like a markup language or style sheet (if you will) to define what you want to tranform your XML data into. PHP provides a way to do xslt processing. Another link at Zend.com has an exhaustive example on how to do XSL transformation on XML to produce HTML. w3.org describes XSL in detail.
XSL is a little difficult to wrap your brain around at first. You may think it's too complicated for the result you want. However, this process is the de facto standard when dealing with XML transformations. It will look nice on your resume as well 😃
P.S. If you do not care about your resume, I'm sure you could extract this data with a regular expression using a function like preg_match for example.
