           Summary: SAXParser always fails when parsing an xml document
           Product: Xerces-J
           Version: 1.4.3
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: SAX
        AssignedTo: xerces-j-dev@xml.apache.org
        ReportedBy: jacques.theodas@enron.com


Whenever I try to parse an xml file with the code below, I get a 
SAXParseException. The exception is included below as well.
I tried parsing many xml files that were verified to be well formed and the 
same error always occurs. Therefore, I think it could be a bug.
To be sure, I used the SAXParser in the JAXP API and had no problems parsing 
the same files.
