Hello all,
I have the following stylesheet which essentially performs an identity transform on a given xml instance, producing a copy with only slight changes (the e.g. below has one of these -- stripping out the concluding punctuation from element 'onlyNum' -- but the actual stylesheet will have more). I would like to produce another document that records these changes, at least as a list containing the original and changed node. this can be either text or xml, something on the lines of:
<onlyNum>E345.</onlyNum> changed to <onlyNum>E345</onlyNum>
I have a feeling this could be done with xsl:result-document, but am not sure how to proceed. Any suggestions would be most welcome. 

Thanks in advance,

Munna
