XML == eXtensible *Markup* Language. XML itself is for exchanging, 
representing and saving structured data, not for processing (though some 
XML-related technologies like XSLT would allow you to do some basic jobs 
on processing). It depends on your task whether XML and XML-related 
things would be enough for you. Just read [0]. You'll see ;-)

HTH, Igor.
