In my last article I covered the use of the expat functions available to PHP for parsing XML documents using the SAX method. The sample code was a class that read the XML document and generated the HTML to present the data in a nice table. This example was far from perfect due to the fact that the presentation of the data was not separate from the class code that had to parse the XML document. This meant that a slight modification to the HTML generated by the class could break the actual parsing functionality of the class.
