Re: attribute closest match

Hello all,
  I am comparing a series of attribute (called 'id') values in one xml file
with same in a second xml file.  If there is an id value in the the second
file which matches, I grab the value of the element and use it.  If there is
no match, I use the Xalan redirect extension element to emit a log file
entry essentially stating that there wasn't a match for that id but can't
provide much more information.  It could be that there is a _nearly_
matching id, e.g. maybe two characters are accidentally transposed.
  I believe that use of computers should make our lives easier.  So what I'd
like to know is if anyone knows of any XSLT templates which can essentially
find a _closest match_ which I could then emit to the log file or do I have
to resort to writing an extension function?

thank you for any suggestions,
