SQL & PL/SQL

Hi All,

I am trying to replace key words with some html tag wrapped around it. The match for keywords needs to be case insensitive but should retain the original keywords case.

So far I have this:

WITH DATA AS
(SELECT 'I seek aN anSwer please' val, 'An Answer' keyw FROM DUAL)
SELECT REGEXP_REPLACE(val,keyw,'<a href="answer_url">'||keyw||'</a>',1,0,'i')rslt,val,keyw
FROM data;

The result is

I seek <a href="answer_url">An Answer</a> please

Is it possible to get the following (i.e retaining the original case of the source)

I seek <a href="answer_url">aN AnSwer</a> please

Thank you

Ligon
