Re: [xsl] limit a string to a certain word count

I am using java to do these transforms.

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

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">

What is the 2.0 equivilant?  Just:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="2.0">

?

Thanks again-
Matt

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.
