Convert Response Body From XML To Json In API Management Policy Expression When Forwarding Response To Different URL

How can I change the response body from XML to Json when forwarding the response to a different URL? I'm specifically forwarding the response to Azure Service Bus. I've tried many

Solution 1:

Here's the solution :) The typical JsonConvert.SerializeXmlNode method isn't allowed in policy expressions.

However good ol' JsonConvert.SerializeObject did the trick.

<send-one-way-request mode="new">
    <set-url>http://requestb.in/xje199xj</set-url>
    <set-method>POST</set-method>
    <set-header name="Content-Type" exists-action="override">
    <value>application/json</value>
    </set-header>
        <set-body>@{
            string xml = context.Response.Body.As<string>(preserveContent: true);
            XmlDocument doc = new XmlDocument();
            doc.LoadXml(xml);

            return JsonConvert.SerializeObject(doc);
            }
        </set-body>
</send-one-way-request>
