RE: Converting Document object (DOM) into inputsource for XSL processing in XT

---

---

  You could write a "DOM to SAX tree walker", i.e. a class
that implements org.xml.sax.Parser and that traverses a DOM
tree in pre order, and for each Element node visited : 

 1) call the 'startElement' method on the DocumentHandler

 2) visit all children elements

 3) call the 'endElement' method on the DocumentHandler

 I've started to write such a class, but I didn't
need it so it is untested, if you want the source,
send me a mail...
