Requesting data from a WCF Service

Hey.
I just finished making a WCF service for a little hobby project.
http://dev.berfenfeldt.com/ScrabbleSolver/ScrabbleSolver.svc?wsdl

I want to send the following XML to the GetPossibleWords Method and view the returned XML.

[XML]
<soapenv:Envelope xmlns:soapenv=“http://schemas.xmlsoap.org/soap/envelope/”>
<soapenv:Header/>
<soapenv:Body>
<tem:GetPossibleWords>
<tem:Word>testletters</tem:Word>
<tem:Contains></tem:Contains>
<tem:BeginsWith></tem:BeginsWith>
<tem:EndsWith></tem:EndsWith>
<tem:SortByWordLength>false</tem:SortByWordLength>
</tem:GetPossibleWords>
</soapenv:Body>
</soapenv:Envelope>
[/XML]

How do I do this in AS3?
