ID/IDREF DocumentReader

["Hookom, Jacob John" <ho...@uwec.edu>]

How can I get IDREF linking if I read in an XML file (with proper dtd) as a DOM?  Will using a Transformer link the nodes properly for me?  Thus far I haven't found a way to get it to work.
 
Thanks!

If the DOM was built with validation turned on, so the DOM knows which 
attributes are IDs, I believe we should be able to retrieve nodes by ID. 
Just retrieve the IDREF's string value and pass it into the XPath id() 
function (see http://www.w3.org/TR/xpath#section-Node-Set-Functions).

If the DOM was build with validation turned off, it doesn't know where and 
what the IDs are and we don't either.
