Generating Request/Response XML from a WSDL
Try this online tool: https://www.wsdl-analyzer.com. It appears to be free and does a lot more than just generate XML for requests and response.
There is also this: https://www.oxygenxml.com/xml_editor/wsdl_soap_analyzer.html, which can be downloaded, but not free.
I use SOAPUI 5.3.0, it has an option for creating requests/responses (also using WSDL), you can even create a mock service which will respond when you send request. Procedure is as follows:
- Right click on your project and select New Mock Service option which will create mock service.
- Right click on mock service and select New Mock Operation option which will create response which you can use as template.
EDIT #1:
Check out the SoapUI link for the latest version. There is a Pro version as well as the free open source version.
