Hi,
XSLT provides a way to convert any xml to any other xml (or even text). Or put in (really) simple words, you use XSLT as a kind of template, where you put in the data of your original xml.
how to make that template strongly depends on what your original xml looks like and what your output should be. There is a tutorial for
XSL and
XPath (the 'address system' for xml) at www.w3schools.com (those got me started).
If you could provide (sufficient parts of) your xml (original and result) I can be of more help.
kind regards
PS: if you now the DOM (Document Object Model (used e.g. in html and JavaScript)) chances are that you will find it quite easy.
PPS: to answer your question - yes, there is. pay someone to do it for you (though this won't get You further)
