I haven't found any other way than just use XSLT to add new tag or remove
the tag from XML file and then reread it in Xalan.
Or You can construct new tree right in the memory using Xalan methods.
One more way: Use Xercer (DOM) and implement Your own XPath.
If You don't need too complicated regex XPath expressions, it shouldn't be
too hard.
