I'm trying to put together a simple test application for xpath now and I've 
noticed, there doesn't seem to be a way in fpc xml implementation to simply save 
to a string, an xml document or node.

ReadXML()
ReadXMLFile()

All have no implementation to write a value to a string, only Text, Stream and 
File.  I have to create an intermediary stream, save it to that and then convert 
that to string or use TStringStream in order to convert them to a string.  Odd.

Also the wiki page:
http://wiki.freepascal.org/XML_Tutorial#Create_a_TXMLDocument_from_a_string

Is incorrect.  The example will error out because the string passed in is 
interpreted as a file path, not as a string representation of an xml document.
