Example

The following example uses the make_request function to invoke a SOAP style Web service that returns movie listings. The result is stored in an XMLTYPE.

DECLARE
    l_envelope  CLOB;
    l_xml       XMLTYPE;
BEGIN
	    l_envelope := ' <?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"

        </tns:GetTheatersAndMovies>
    </soap:Body>
</soap:Envelope>';

l_xml := apex_web_service.make_request(
    p_url => ' http://www.ignyte.com/webservices/ignyte.whatsshowing.webservice/moviefunctions.asmx',
   p_action => ' http://www.ignyte.com/whatsshowing/GetTheatersAndMovies',
