Is there a concise description somewhere as to how they differ, are
there a large number of xslt regular expressions that are compatible
with Java regular expressions or are they basically incompatible? I
would suppose the main difference is that XSL-T regular expressions
are Unicode compatible regex's - correct?
Cheers,

Java regular expressions and XPath regular expressions are not the same
thing!
