Which approaches can be used for extracting data from a SOAP body and returning it...

Use XSLT to transform the XML payload and then use a XML to JSON policy

Use XML to JSON policy first to convert to JSON and then ExtractVariables with a JSONPath to extract the body from the converted SOAP envelope

Use ExtractVariables with an XPath first to extract the SOAP body and then use XML to JSON policy

Use an AssignMessage policy to convert the SOAP response to a JSON response, using XPath expressions to retrieve the data
