You have both missed my point. I want an XSLT stylesheet to compared

files. Maybe I shouldhave not said "Visual".
I am wondering how to do a visual diff of two XHTML files, one newer
one and a second older one, showing new text in green and
old text in
red strike through.
I need to do this in XSLT 1.0 if it is at all possible, although I
would have thought it was as its a Turin computable problem.
Many thanks in advance,
Anyone give me any clue how to approach this problem ?
Michael,
Thanks for the reply.
Apparently this is not a task that would be very easy to do in XSL,
depending on the level of detail you want in the result. >It would be no

Right, I thought it would be a tough problem if possible at all.
I am currently evaluating those options to handle the diff task:
* http://nwalsh.com/java/diffmk/ [not under development]
* http://xmlunit.sourceforge.net/ [active development]
These are Java and I am not running Java on our servers so is not a
solution for me :(
* http://www.xmldifftool.com/ [author says a new version is under
development]
This is closed source.
Okay, please let me know what you find. I will have a look too, when I
get the time and right head on.
I had been considering a DOM based solution too.
I think a DOM solution in PHP or Javascript is what I am going to have
to consider.
Javascript solution would be better if you want to open source it
afterward, in case it ends up to be general diff
I am looking at a possible DOM + Hashing + LCS solution. What I am
going to code it in I have not descided yet, probably PHP.
