Thanks for replying.
I am ok with parsing up to it. How do you shut down
the parser? I see no shutdown/stop call in XMLReader.

This is the way I had planned to implement looking for
a node, but it will not stop the unnecessary parsing.
In startElement() at the very beginning:

 if (qualifiedName.equalsIgnoreCase("Node")) {
  if(!inRequiredSubtree) {
    if(idToLookFor == id)
      inRequiredSubtree = true;
    else {
         return;
    }
  }
...process
}

In endElement():
if (qualifiedName.equalsIgnoreCase("Node")) {
  if(id == idToLookFor) {
   inRequiredSubtree = false; 
   return;
  }
  if(inRequiredSubtree) {
...process
  }
}

thanks,
Anil
