Hi everyone,
I posted a question asking about dynamically generating XSL
definitions for XML (versus having a physical XSL file).
I recieved a few emails from people asking me to let them know if I find a
solution. I'm happy to say that I have. Thanks to Steve Maring who works
with me (dont look too far from home for answers huh? :)
Excuse the long code fragment that is to follow:
Note to run this.
1) Just give it a name of an output file (something.html)
2) Make sure that you have j2ee.jar, xerces.jar, and xalan.jar in ur
classpath.
I hardcoded the XML and XSL definitions inside the code but you can see how
these can be dynamically generated as Strings from a java class.
Hope this helps :)
