XML SAX well-formedness Error Reporting.
Hi,
We are developing an module which reads data from XML File & we are using
SAX Parser for parsing.
Below is the pseudo code for the same:
XMLReader xmlReader = XMLReaderFactory.createXMLReader(
"org.apache.xerces.parsers.SAXParser" );
xmlReader = XMLReaderFactory.createXMLReader();
SAXXMLHanlder handler = new SAXXMLHanlder();
xmlReader.setContentHandler(handler);
xmlReader.setFeature("http://xml.org/sax/features/validation",true);
SAXXMLValidator errorHandler = new SAXXMLValidator();
xmlReader.setErrorHandler(errorHandler);
xmlReader.parse(...);
We also have SAXXMLValidator Class implementing ErrorHandler, which just
prints error messages to Logs.
The issue is, when the XML Document is malformed, errors are reported in
the logs and the execution proceeds ahead. There is no Exception thrown out
for any well-formedness error.
Is this the usual behavior? Or are we missing anything out, as we want the
processing to halt if XML is not well-formed.
Any ideas in this regards would be highly appreciated.
Thanks,
Khyati

Hi,
Yes you are right, as am new to XML, I realized that there is a confusion
between Validity Errors and well-formedness Errors.
For Validation Errors no Exception was thrown out by our ErrorHandler
Implementation, and hence the parsing continued.
Only for Fatal Errors i.e. well-formedness Errors it used to stop parsing.
Now we rethrow the Exception for Validity Errors, hence the parsing halts.
Thank you very much for the reply !
Thanks,
Khyati

That's very strange and shouldn't happen. Does parsing continue, or does
parsing stop with no exception? Are you sure you aren't confusing
well-formedness and validity errors? They aren't the same, and don't
have the same effect.
If nothing else, you could always just rethrow the exception from your
error handler. You have to do this for validity errors. I don't think
you should have to do it for well-formedness errors though, but maybe
that's changed. Do you have a reproducible test case?
