Hi Yeah, i have checked out PsychoPath source code,i think it is a good idea to merge PsychoPath with Xalan, it will support nearly all the XPath 2.0 implemention for Xalan. After that, my task is to implement the other XSLT 2.0 specification for Xalan,this solution really speed this project up much.

It is already being used by Xerces-J for XSD 1.1 Assertion support. Why re-invent the wheel if you can leverage something that already exists. http://wiki.eclipse.org/PsychoPathXPathProcessor PsychoPath already is XML Schema Aware, leverages Xerces-J 2 and passes about 99.9% of the Xpath 2.0 test suite.

If i finish it first,may be some guys can go it into service. Months ago,i was working with a XSLT project based on Xalan, i need some XPath 2.0 functions,but i have to finished them by Xalan extension mechanism one by one, it is a boring work, so ,i think, if some one implements these XPath 2.0 functions already, how beautiful the world is! But i want to say that implementing functions is just a pre-handler job for Xalan's XSLT 2.0 implemention job, it must be done sooner or later, so i have started it,it won't go wrong. Then start with which parts,schema change,sequences change or some utility parts, i am not very sure, so,i need your help,all of you can give me some advises. 2010-03-27 ustbcoder 发件人： Michael Ludwig 发送时间： 2010-03-27 04:39:44 收件人： xalan-j-us...@xml.apache.org 抄送： 主题： Re: Re: implement XPath 2.0 function for xalan xunlong gui schrieb am 26.03.2010 um 23:27:15 (+0800): > 1.implements all the XSLT 2.0 functions which do not need sequences > and XSLT 2.0 schema support Leaving aside (W3C XML) schema awareness, the new type system of XPath 2.0 seems the most fundamental change from 1.0 to 2.0, so I wonder whether focussing on the utility parts would be a good start for any effort to go to 2.0? -- Michael Ludwig
