I am trying to extract 2 nd value in the the sting sunil;1000;kumar
SQL> select regexp_substr('sunil;1000;kumar','[^;]+',1,2) from dual;

REGE

1000
This works fine.
But, when the second field is null, ie., sunil;;kumar
I want the out put to be null only. 
SQL> select regexp_substr('sunil;;kumar','[^;]+',1,2) from dual;

REGEX

kumar

i know the beta won't work with dtds. Is this feature
gone for good from jaxb or just the beta? I read the
FAQ http://java.sun.com/xml/jaxb/faq.html. and it
seems like it says dtd is gone, but doesn't come out
and clearly say so.
Hi,
The dtd feature support is no longer there in JAXB. The beta release does not support dtds and also the FCS will not be supporting it.

Thanks,
