How to detect the Invalid XML Character ?

[sachinik19]

Hi,

We are using SAXParser (xerces) for parsing an xml with utf-8 encoding.
For some special character it gives SAXException with error message -
"The invalid character is found in the document ". But for other errors
also it gives the same Exception only with different message.
Is there any way to detect that the error is because of the invalid
character in xml ?

Or

if there is any profile to check whether the xml contains any invalid
character or not??

thanks in advance

Run a standalone parser that gives you line number and character number,
eg onsgmls, rxp, etc.

Unfortunately, SAXExceptions don't carry any sort of standard code to
describe the failure. Check your specific parser implementation; it
_might_ have added this information... but that will be a nonportable
solution, if so.

Simplest answer may in fact be to implement your own parser which does
present that information, or to get hold of an open-source parser like
Xerces and add this feature to it. Again, the problem is that this isn't
portable to other parsers unless they have the same tweak.
