Re: [xsl] XSLT Saxon Transformation in JSP pages ?

thanks a lot Rob, this is exactly what I was looking for. I will have a
look at the code to try to adapt it so I can use saxon engine.

Hi,

You will probably want to create a Templates object to cache and create
you Transformer off of that. You will get better performance.

Also, before you write your own taglib, you might want to check out:

http://jakarta.apache.org/taglibs/doc/xsl-doc/intro.html

If you don't like it, at least you can use it as a starting point.

best,
