Azure APIM - XML to JSON Conversion - json

Question

I am trying to figure out how to properly use the XML to JSON conversion in the Azure APIM Policy Editor. I've seen dozens of examples where all that's identified is this:
<xml-to-json kind="direct" apply="always" consider-accept-header="false" />
However, I cannot find the appropriate place within my policy to place the code to make it do what I'm expecting. Here is my Outbound policy, which is where I am looking to use this:
<outbound>
<base />
<choose>
<when condition="#(context.Response.StatusCode < 400)">
<set-body template="liquid">
{% if body.envelope.body.GetProjectsByQueryResponse.GetProjectsByQueryResult %}"{{body.envelope.body.GetProjectsByQueryResponse.GetProjectsByQueryResult | Replace: '\r', '\r' | Replace: '\n', '\n' | Replace: '([^\\](\\\\)*)"', '$1\"'}}"{% else %} null {% endif %}
</set-body>
</when>
<otherwise>
<set-variable name="old-body" value="#(context.Response.Body.As<string>(preserveContent: true))" />
<!-- Error response as per https://github.com/Microsoft/api-guidelines/blob/master/Guidelines.md#7102-error-condition-responses -->
<set-body template="liquid">{
"error": {
"code": "{{body.envelope.body.fault.faultcode}}",
"message": "{{body.envelope.body.fault.faultstring}}"
}
}
</set-body>
<choose>
<when condition="#(string.IsNullOrEmpty(context.Response.Body.As<JObject>(preserveContent: true)["error"]["code"].ToString()) && string.IsNullOrEmpty(context.Response.Body.As<JObject>(preserveContent: true)["error"]["message"].ToString()))">
<set-body>#{
var newResponseBody = new JObject();
newResponseBody["error"] = new JObject();
newResponseBody["error"]["code"] = "InvalidErrorResponseBody";
if (string.IsNullOrEmpty((string)context.Variables["old-body"]))
{
newResponseBody["error"]["message"] = "The error response body was not a valid SOAP error response. The response body was empty.";
}
else
{
newResponseBody["error"]["message"] = "The error response body was not a valid SOAP error response. The response body was: '" + context.Variables["old-body"] + "'.";
}
return newResponseBody.ToString();
}</set-body>
</when>
</choose>
</otherwise>
</choose>
<set-header name="Content-Type" exists-action="override">
<value>application/json</value>
</set-header>
<xml-to-json kind="direct" apply="always" consider-accept-header="false" />
</outbound>
As you can see I've tried placing the conversion line at the very end of the outbound policy, but it's not doing what I expect; I still have an xml document returned.
Any help here in understanding how to revise my policy to work would be wonderful.
