not everyone shares that sentiment. in terms of lowest common denominator
XML is also a string. then there is the question of whether it's actually
marked as XML, whether there is valid DTD and whether the XML itself validates
against the DTD - if any of the answers is 'no' then your looking at tag soup.
there is a lot more tagsoup in this world than there is proper xml.
that said it can't hurt to throw simpleXML at the problem :-)
