Re: limit a string to a certain word count

Not sure if it supports 1 or 2, but I noticed that my XSL has the
following XML header:

Thanks again-

Depends if your 1.0 parser supports str:tokenize (a EXSLT function). If
it does, then it not a "fair bit harder" but it will be "a wee bit
harder" :)

See here:

I think Xalan supports this function if you are using it.
