Re: [xsl] searching for occurrences of unique string-value and replacing with string value of another node

[Julie <julie.newcome@xxxxxxxxx>]

Thank you for your reply, Michael.

I put this code in but I do not get a result for the link, just ".html".

I can evaluate the xpath expressions through xmlspy, but this is a
function so that doesn't work...is there any other way to evaluate
what is in the key?
