XML Transformation

poornewbie

Hi experts,

imagine you have the following xml file which tags have to be changed into another structure. i.e. an xml file has to be transformed into another xml file using patricular tags. the output should be rendered containing the new xml-tags as an xml tree and neither as text nor as html???
how can this be done??

I would appreciate every mini tipp.......
thank you in advance!!!!
Markus
