XmlNode version 0.1
Author: Mike Neugebauer
The following class works only in PHP 5 (tested in PHP5RC2) and is
intended as a supplement to SimpleXML. SimpleXML works well
for parsing and reading through XML documents. The XmlNode class
is intended for developers who need to generate an XML document
on-the-fly in PHP 5.
This class assumes that you are going to setup an XML document from scratch in the
order that the XML elements are supposed to appear. It also assumes that you
know exactly how you want the XML document to be structured. It isn't indended to
support XML Schemas, DTD's, validation or updates and additions to previously
existing XML structures.
