Well, If you are free to change the XML structure at any time - where's the point in wondering if an element is a parameter, a CDATA or an element? You can change everything to element and CDATA and that's all. If you have a fixed XML structure, that's not supposed to change, having a DTD is obligatory in orther to maintain consistency of the format. So, you can either work without using getType (since you define the XML structure yourself), or use a more complex API that will serve you well. > > <?php > //These are my 2 XML documents.
