You have both missed my point. I want an XSLT stylesheet to compared
or merge XML(XBEL)/XHTML files resulting in XHTML or XBEL output
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 fun 
at all to implement a longest common string algorithm in XSL 1.0. So, it

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.
