Parse BPEL Output in PL-SQL

Question

Hello,
I am invoking WSDL from PL/SQL and WSDL is returning following output.
+<?xml version="1.0" encoding="UTF-8"?>+
+<SOAP-ENV:Envelope+
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
+<SOAP-ENV:Header+
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"></SOAP-ENV:Header><SO
AP-ENV:Body>
+<ser-root:soapIntefraceASVOutput+
xmlns:ser-root="http://eai.corpit.microsoft.com/microAccountValidation/provider/Acc
ountStringValidator"><acctStringValidateOutput>
+<status>112</status>+
+<message>In+
valid account segment
code</message></acctStringValidateOutput></ser-root:soapIntefraceASVOutput></SOA
P-ENV:Body>
+</SOAP-ENV:Envelope>+
I wanted to parse this XML in my PL/SQL Block and wanted to retrieve <status> and <message> element Value.
Please help me on this.
Thank You

using XPATH and a SQL you can get it.
eg:
-- test with 10gR2
CURSOR grab_one_value(xt IN xmltype, path_to IN VARCHAR2) IS
SELECT extractvalue(xt, path_to, c_namespace)
FROM dual;
OPEN grab_one_value(xml_in, tag_in);
FETCH grab_one_value
INTO v_out;
CLOSE grab_one_value;
RETURN v_out;
