Re: [xml-dev] matching text with regexp in xpath

Title: Message

If you want "replace" functionality, you could wrap the Jakarta ORO package as Java Extensions in your XSLT code. We found the behavior of the regexp JDK 1.4 to be erratic.  Either the ORO or the Regexp Package from the apache foundation are pretty solid, specially if you want compatibility with Perl syntax.

 

http://jakarta.apache.org/oro

http://jakarta.apache.org/regexp

 

Please keep us informed of your progress. We're working on Regexp support for XSLT ourselves.

This will be available in XPath 2.0. It's not difficult to do by writing extension functions, using any of the Java processors together with the regex libraries in JDK 1.4, especially if all that you want is a boolean "match" function.

Subject: [xml-dev] matching text with regexp in xpath

Hi,

I was wondering if anybody knows of an extension function to XPath which allows me to match text and attribute values in XML documents against regular expressions.  I'd like to be able to write something like:

        /a/b[re:match(@c, '{.}')]

to match all elements where an attribute has a value matching the regexp {.} (AVT) or:

        /a/b/@c[re:match(., '{.}')]

to match the attribute elements themselves.

If there isn't such a thing yet I imagine it shouldn't be to hard to write.  Can somebody give me some hints/directions on how to get started with this?

Thanks,
