Hi Shah,

The output of your first xslt policy will always be saved into the API Gateway Context's message.body.  On the invoke policy that follows, you have the option to save the response to some context message using the output property, with "message" being the default message, ie, message.body, message.headers, and message.status will be updated by the invoke policy.  If you're using the default, then you have effectively overwritten the result of the first xslt policy.  Instead, specify a different message on the output property of the invoke, for example, specify "invokeResponse" then the invoke will update invokeResponse.body, invokeResponse.headers, invokeResponse.status.  Now message.body from the first xslt will be available for your second xslt policy.  The second xslt can consume message.body by using the input check box on the xslt policy, or within the xslt policy using the apigw:read-payload extension function, specifying the message name of "message" for message.body or "invokeResponse" for  invokeResponse.body.  Documentation on this extension function can be found at https://www.ibm.com/docs/en/datapower-gateway/10.5.0?topic=functions-apigwread-payload.  The output of your second xslt policy will also be message.body, overwriting  your first xslt policy output, so if you need that further, you'll need to use either use a set variable policy to copy message.body to some other context variable, or you could also within your first xslt stylesheet use a set-payload extension element, see https://www.ibm.com/docs/en/datapower-gateway/10.5.0?topic=elements-apigwset-payload, to save the same output so it doesn't get overwritten.

Steve
