Hello,
Im sure that many of you would have encountered the
problem I would describe, 
I have an input file xml file 

<Name>
<FirstName>
Joe 
</FirstName>
<SecondName>
Somebody 
</SecondName>
</Name>

and this does not have any mention of DTD or Xml
schema in it.
I would have a xml schema file named (name.xsd) 
which specifies that <FirstName> and <LastName> cannot
contain any numbers!

Now,I am using a SAX parser and am using xerces 2.2.1
I tried with the Counter.java file that comes alog
with in the /sax directory.
I also created my own EntityResolver called
MyEntityResolver() and added a System.out.println("
Entity Resolver called") in the resolveEntity()
method..

In Counter.java , I added the below code
parser.setEntityResolver(new MyEntityResolver())
and the respective flags in Counter.java are all set
to true and the parser is the
org.apache.xml.parser.SAXParser ( which is the
DEFAULT_PARSER in Counter.java) 

I expected the resolveEntity method to be called..
but it is not happening...
Whats missing ?? 

DO any of you have some code example,
that would validate my plain xml file ,
against a schema or an dtd , which is specfied at 
runtime ???

Thanks
Harish
