How to set variables in XML document? 2007-04-04 - By Robert Houben
You could also use an XPath to select "//*[contains(text(),'${foo}')]"
(select all elements with a text node that contains your variable) which
is also a Xalan-J feature. You could then traverse the node-list that
comes back and do the substitutions yourself.

This is a Xalan-J users forum. Your question seems to be related to,
how to use DOM API (with Xerces I guess). You should subscribe to
j-users@(protected) for that.
But I can try to answer your question.
If you have got a XML document wrapped in org.w3c.dom.Document, then
Document interface doesn't provide any method to do something like
doc.setVariable("foo", "bar"). I think XSLT will be more suitable for
this task. And you can use Xalan-J for that.
I think you have to traverse the DOM object, and reach to the
concerned text node (${foo} -- wrapped in org.w3c.dom.Node). Then you
can modify the value of this node.
