Introduction to XML_Util
XML_Util is a utility class that helps you working with
(and especially creating) XML documents.
All methods of XML_Util can be called statically, that
means you do not have to instantiate an XML_Util object
to use the provided methods.
The funcionality of XML_Util ranges from validating an XML tag name (as there are strict
rules for tag and attribute names) to the creation of namespaced XML tags.
