Hi Mukul, Thank you for your reply. I know Xalan's extension function mechanism, but my xslt 2.0 function implemention is different with extension function.For example, we have the following XML document:
<?xml version="1.0"?> <doc> <name first="David" last="Marston">David Marston</name> <name first="David" last="Bertoni">David Bertoni</name> <name first="Donald" last="Leslie">Donald Leslie</name> <name first="Emily" last="Farmer">Emily Farmer</name> <name first="Joseph" last="Kesselman">Joseph Kesselman</name> <name first="Myriam" last="Midy">Myriam Midy</name> <name first="Paul" last="Dick">Paul Dick</name> <name first="Stephen" last="Auriemma">Stephen Auriemma</name> <name first="Scott" last="Boag">Scott Boag</name> <name first="Shane" last="Curcuru">Shane Curcuru</name> </doc> If we want to find the guys with first name end with "d",we should use this XPath to get these guys: XPath: /doc/name[ends-with(@first,'d')] --------------------------------[1] And also, if we use Xalan's extension function mechanism to achieve our goal, we can use Xalan's str extensin function (http://exslt.org/strings) to achieve our goal,also, we should offer a expresion like this: expresion: str:endswith(/doc/na...@first],'d') -----------------------------[2] Let's compare [1] and [2], we can find that [1] is the normal XPath expresion in XPath 2.0,but [2] is not. If we google some key words such as "xpath ends-with" or "xpath upper-case", we may found many developers want to know why XPath with functions "ends-with","upper-case"(XPath 2.0 functions) can not execute correctly,especially some junior developers, I think this confuses them. So, this is why i want to implements XPath 2.0 functions for Xalan. And implementing XPath 2.0 functions is just small part of my job. I want to implement XSLT 2.0 datamodel too, and then implement all the XSLT 2.0 recommendation for Xalan. Michael (Michael Glavassevich/E-mail: mrgla...@ca.ibm.com E-mail: mrgla...@apache.org) told me XSLT 2.0 is a large specifications and that could take the developers years to implement correctly,So,I want to achieve this step by step.
