/Sharad Singh/:
I am using the SAXParser provided in the xerces.jar through which i am
able to validate xml based on dtd validations. Now I need to extend the
Saxparser functionality so that i can define some additional rules and
perform validations on that rules. Can anyone please tell me how can i
do that?
for EXAMPLE i would like to validate expression : a+(b+c)
on following grammar that the brackets are properly closed and the
operator + must have two operands....
I will have the expression written in the xml as
<mytag> a+(b+c) </mytag>
So you have already written an |org.xml.sax.ContentHandler|
implementation to read the element text content? Then you process it
in whatever fashion you need and you could throw a
|org.xml.sax.SAXException| (you may make a subtype you handle
specifically) from your handler to terminate the parsing if
something is not valid - all handler methods are declared to throw
|org.xml.sax.SAXException|. That content validation of course is
specific to your application and is not something you could get out
of the box using standard XML validation.
