Jay,
Wow. Lots of code there. Thank you though...just wish there were an
easier way to accomplish the task!
Thanks

We had a very similar question last week, except that that person was
getting the string from a node in the document and didn't care about a
string-compare function. Assuming you also don't care about a
string-compare function, here's a modification of last week's answer that
does the job with a recursive template. If you really do want to use a
string-compare function, someone else will have to answer your question,
as I don't use MSXSL.
Note that my solution is case-sensitive, so Hello, hello, cat and Cat are
all different words.

Subject
[xsl] duplicate occurances within strings
If i have a variable $thestring containing the following string:
"Hello, Hello, Hello, test, dog, cat, cat"
Is there a way to use the string-compare function to parse it and
check for duplicates within the string, and then possibly remove those
extra occurrances...resulting in the string "Hello, test, dog, cat"
Thanks
Chris
