Transforming XML to fixed format file

Hi

I have a requirement to transform an incoming XML file containing Purchase
Orders into a fixed format file (specifically an SAP IDOC). This will
involve things such as, placing the text value of the node <accountnumber>,
into positions 10-19 of the output file. Is this something I can do easily
with XSLT or is this an instance of the situation where I'd be better off
writing my own parser by extending XMLReader.

Regards
Roger
