Unsuccessfully attempting to capture XML being sent to a WebService

Question

So I am having an issue with data passed to a webservice mapping correctly. I am attempting to capture the XML from a .net C# application as it is passed to the webservice. I have tried using Fiddler and system.diagnostics in the web.config but I only get a result in the file created by the system.diagnostics. I am running via localhost, over a VPN (proxy server) to the webservice. Below is the code from the web.config and what it returned. Any assistance getting this returning the data would be awesome.

Code:

<system.diagnostics>
    <trace autoflush="true">
    </trace>
    <sharedListeners>
      <add name="console"
      type="System.Diagnostics.ConsoleTraceListener" traceOutputOptions="DateTime" />
      <add name="file"
      type="System.Diagnostics.TextWriterTraceListener" initializeData="testrequest.log"
          traceOutputOptions="DateTime, Callstack" />
    </sharedListeners>
    <sources>
      <source name="LowLevelDesign" switchValue="Verbose">
        <listeners>
          <add name="file" />
        </listeners>
      </source>
      <source name="System.Net.Http" switchValue="Verbose">
        <listeners>
          <add name="file" />
        </listeners>
      </source>
      <source name="System.Net.HttpListener" switchValue="Verbose">
        <listeners>
          <add name="file" />
        </listeners>
      </source>
      <source name="System.Net" switchValue="Verbose">
        <listeners>
          <add name="file" />
        </listeners>
      </source>
      <source name="System.Net.Sockets" switchValue="Verbose">
        <listeners>
          <add name="file" />
        </listeners>
      </source>
    </sources>
  </system.diagnostics>

Result from the generated file.
