Most PHP programmers will eventually run into an XML data set. The easiest way to deal with this data is using the SimpleXML extension for PHP. In this course, David Powers walks through loading and extracting data from a basic XML document, working with namespaces, and editing XML elements and attributes with SimpleXML and the XPath query language. He also shows practical uses for XML, such as displaying text as well as images from an RSS feed, and the process for generating new XML documents from scratch with SimpleXML.
