No problem here. You should use org.apace.xpath.XPathAPI or CachedXPathAPI.

This is unfortunetely not possible in the moment. Please refer to:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=18684
<http://nagoya.apache.org/bugzilla/show_bug.cgi?id=18684>
for the proposed extension mechanism that would allow this functionality.
To try this, you'll have to retrieve CVS state on 2003-04-04 to apply these
changes and recompile Xalan.
You can contact me via Xalan's mail list (as I originated this report) to
clarify ideas used in it.
Thanks,
Dimitry

Subject: XPath extension functions
Hello everyone,
First I will say that I'm totally new to Xalan.
Here is my question.
In fact, I would like to use Xalan only for its Xpath capabilities.
I have an XML file and would like to use the Xpath functions to 'query' this
document without using any XSL capabilities (so without any stylesheet). I
just to use the Xalan XPath API from myu own Java code.
I don't think it should be a problem ???
However, in my case, I need to have an ends-with() functions. As it does not
exist in the XPath specification I assume it does not exist in Xalan either
(I may be wrong since I haven't used Xalan yet but I read many times that
Xalan followed the W3C specs,so..).
More, I've read on the Xalan web-site that it was possible to extend the
core library of functions that XPath provides.
I was wondering if it was possible to 'declare' my ends-with() function and
use it in my XPath expression using the Xalan Xpath APIs as well as if it
was a native function (like for example /doc/param[ends-with(@(protected),'lan')])
?
Thanks in advance,
Jérôme.
