Oracle DBMS_XMLQUERY - Remove <?xml version = '1.0'?> Tag

I am using the DBMS_XMLQUERY package to generate some XML from a query.  I am interested in turning off the <?xml version = '1.0'?> header tag that is returned with the XML document.  I attempted the following unsuccessfully:

DBMS_XMLQUERY.setencodingtag (v_xml_query, '')

The document still comes back with the <?xml version = '1.0'?> header tag.

Can anyone tell me how to turn this off?

Thanks.

Using DBMS_XMLQUERY.setencodingtag (v_xml_query, '') will only clear out the encoding part of the header text, which would be the "encoding = 'UTF-8'" part in the example below:
<?xml version = '1.0' encoding = 'UTF-8'?>

There is no way to not generate this, all you can do is manipulate the returned CLOB to remove the tag, for example:

CREATE OR REPLACE FUNCTION get_xml(queryStr VARCHAR2) RETURN CLOB AS
    v_ctx_handle DBMS_XMLQUERY.ctxType;
      v_results CLOB;
      v_instr INTEGER;
BEGIN
       v_ctx_handle := DBMS_XMLQUERY.newContext(queryStr);
       v_results := DBMS_XMLQUERY.getXML(v_ctx_handle);
       DBMS_XMLQUERY.closeContext(v_ctx_handle);

       v_instr := INSTR(v_results, '<ROWSET>') - 1;
       IF (v_instr > 0) THEN
             DBMS_LOB.ERASE(v_results, v_instr);
       END IF;
       RETURN v_results;
END;

I'm sorry for not following up sooner...I got wrapped up in another project and completely forgot about the question I posted.  I've increased the point level 100 points (from 300 to 400) for my oversight.

Thanks
