SQL & PL/SQL

We get a XML response from a WEB-SERVICE.

I convert it to VARCHAR2.

Now, I want to get the actual reponse which is in the Response tag.

I tried this:

DECLARE

  v_1 VARCHAR2(30000) := '<soap:Body><ns:ProcessArgusFeedsResponse xmlns:ns="urn:PegaRULES:SOAP:ArgusToPegaFeeds:Services">' ||

                          '<Response>Good</Response></ns:ProcessArgusFeedsResponse></soap:Body>';

  v_response VARCHAR2(100);

BEGIN

   DBMS_OUTPUT.PUT_LINE(V_1);

   v_response := REGEXP_SUBSTR(v_1, '/<Response>(.+?)<\/Response>/');

   dbms_output.put_line(v_response);

END;

This does not work.

Any help would be greatly appreicated.
