If you're asking for a way to use the XPath API of Xalan-J without
using DTM, it's not possible without rewriting large parts of the
processor; the implementation of XPath and XSLT in Xalan-J is built upon
DTM.
Joseph Kesselman did some work on a revised DTM implementation over
DOM which, if I recall correctly, does not rely on a DOM node to be always
the same Java object, but I don't believe that work was ever completed. If
you're interested, you can take a look at the code in the xslt20 branch of
the xml-xalan project, in the org.apache.xml.dtm.dom2dtm2 package.
Thanks,
Henry
