Problem using XERCES JAVA 2 DOM

[dorin]

I wonder if anyone can help me with a problem using the DOM
getElementById method.

I am using the Xerces Java 2 library to parse an XML file and create and
validate the DOM Document. I am able to access the Node objects using
the getElementsByTagName method but whenever I try to us getElementsById
the method just returns null.

I'm trying to get a project working quickily for a paper and this is
slowing me down greatly. Any advice would be greatly appreciated.

cheers,
Dorin

You need to have a DTD for the XML which declares attributes of type ID
to be able to use getElementById successfully.

I do have an XML Schema which declares attributes of type ID. Is a
schema not good enough? It seems silly that I should need a DTD when I
already have a Schema. Does getElementById not work with Schemas?
