Subject: Help in validating.
Hi All,
I'm using xerces to validate my xml document with schema. I'm setting
ErrorHandler and i;m able to validate. When i get a exception, i'm able to
get the error message and the line number. Even though it gives me the
element name in the error message, is there any way i can get the element
name alone where the error has occured. I mean just like the line number, i
would like to get the element name.
Your help in this is highly appreciated!!!!
Thanks
Ragu
