XPath transformation

[wjfang]

Hi all,

I come across this problem.

I have an XML file A.xml, which follows the schema A.xsd. Then I can
use XSLT to transform A.xml to B.xml that follows the schema B.xsd.

In my case, A.xml is users' view, but it is actually saved as B.xml.

Then users use XPath to query over A.xml. Now what I need to do is to
tranform A.xpath to B.xpath which is valid according to B.xsd, evaluate
B.xpath over B.xml, and transform the result back to one following
A.xsd.

Are there any available solutions towards this problem? Any
suggestions? Thanks a lot!

Cheers,
