Michael,
In ErrorHandler, I tried to implement to query the property but at run time it
gave me belwo error. It looks like that I am querying the wrong property. I
tried to find the appropriate property but could not .
What property should I use so that I can get the current element node when
validator throws error ? Please find the attached file for reference .
Progrma started
instance error org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid
content was found starting with element 'Doc:Id1'. One of
'{"urn:swift:xsd:swift.eni$camt.028.001.02":Id}' is expected.
org.xml.sax.SAXNotRecognizedException:
http://apache.org/xml/properties/dom/current-element-node
Program ended
Thanks
ajay.
