Need some SOAP help

[jonsjava]

Ok, I suck at soap.  I have no idea how to implement a SOAP client.  Could someone help me? This is how my soap request should wind up when I post:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ws="http://ws.*******************">
   <soapenv:Header>
      <username xmlns="http://****************">*************</username>
      <password xmlns="http://****************">*************</password>
   </soapenv:Header>
   <soapenv:Body>
      <ws:LookupSubscribersRequest>
         <Debug>false</Debug>
         <SubscriberKeys>
            <SubscriberKey>
               <SubscriberRealmKey>
                  <Name>DEFAULT</Name>
               </SubscriberRealmKey>
               <Name>$variable</Name>
            </SubscriberKey>
         </SubscriberKeys>
         <ResponseGroups>
         </ResponseGroups>
      </ws:LookupSubscribersRequest>
   </soapenv:Body>
</soapenv:Envelope>

of course, I sanitized it, and $variable will be filled in by my script. Aside from that, this is the request.  Can someone point me in the right direction?

I'm not sure what else I can add to this post to get some help.  I'm not one to ask for help (I usually try to figure things out on my own). I believe that to date, I've only asked for help 3 times.  I've tried figuring out NuSOAP, and using the PHP-SOAP built-in handlers, but I'm just not getting it.  Give me a switch, or custom function any old day *sigh*.  If someone can just tell me the transmission method used in SOAP, I'll build my own connector (rather than learn how to add fully custom SOAP headers).  I just need some direction.
