Parsing XML in JServer

Question

I appologize for my XML ignorance up front. We've got an application with which we store a bunch of different file types in Oracle BLOBS. Some of these files are XML documents which are primarily used by an external application. There is a component to our app where we need to parse these documents and do some lightweight processing. I've done the following so far:
1. Loaded xmlparserv2.jar into the database using loadjava.
2. Written a java stored procedure that reads an XML document from a BLOB and attempts to parse it.
The problem is the DOCTYPE element in the XML document. It typically looks like this:
<!DOCTYPE Screen SYSTEM "c:\loc\screen.dtd" >
This DTD location makes sense only to the external application which uses this XML document (outside the scope of our database). I can't use a DTD in this location. Currently, I massage the xml doc as I read it out of the database so that it points to a DTD I can actually access. I hate this solution. Is there a way to tell Oracle's parser to ignore the DTD component in the xml document, or to use a different one?
Thanks in advance,
Tom

Answer 1

I was totally ignorant on this one. For those just as ignorant, here is the answer:
Before parsing the XML document; parse the DTD document (the one in your known location) beforehand:
parser.parseDTD(dtd_location, nodename);
dtd = parser.getDoctype();
parser.setDoctype(dtd);
parser.setValidationMode(true);
parser.parse(xml_location);
BTW, I recommend the new offering from Oracle Press: ORACLE XML Handbook.
