Parsing Soap

I am getting the following SOAP response from a server call - have it inlined for testing:

var t:XML =
<s:Envelope xmlns:s=“http://schemas.xmlsoap.org/soap/envelope/”>
<s:Body>
<GetTotalPointsResponse xmlns=“http://tempuri.org/”>
<GetTotalPointsResult>
<return>858000</return>
</GetTotalPointsResult>
</GetTotalPointsResponse>
</s:Body>
</s:Envelope>;

I can get the Body using:

var n:Namespace = t.namespace();
var body:XML = t.n::Body[0];
trace(body);

But I need to get the 85800 inside the <return> tags. Anyone? I’m new to using namespaces in XML, so am banging my head on this one.

thanks
