Try to validate your input file with any xml-validator, for example this: Xml validator

You are definitely not parsing that document using DOM you are parsing it using SAX. I'd check the document you are trying to parse as apparently that document is not valid.

UPDATE: Apparently I was wrong. Didn't know that DOM throws that exception too.
