SOAP implementation of UPnP architecture

I am trying to implement UPnP AV control point. i completed till description phase of the architecture. To get the contents of the server from browse action, I am using CURL command as below.

curl -o response.xml -H "Host: 192.168.1.47:2869" -H "Content-Type: text/xml; Charset="UTF-8"" -H "SOAPAction: "http://192.168.1.47:2869/upnphost/udhisapi.dll?content=uuid:67240e36-10e0-45f6-9c4b-e18cdd53360e"" -d @request.xml -X POST http://192.168.1.47:2869/upnphost/udhisapi.dll?control=uuid:99261858-3c45-41b5-87fd-3f30b4700005+urn:upnp-org:serviceId:ContentDirectory

The URL under SOAPAction is the service description url of the server. The URL after POST is the control URL of the server.

My request.xml is as below:

   <?xml version = "1.0" encoding="utf-8"?>
   <s:Envelope
        xmlns:s = "http://schemas.xmlsoap.org/soap/envelope">
        s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding">
        <s:Body>
           <u:Browse xmlns:u="urn:schemas-upnp-org:Service:ContentDirectory:1">
                   <ObjectID>"0"</ObjectID>
                   <BrowseFlag>"BrowseDirectChildren"</BrowseFlag>
                   <Filter>"*"</Filter>
                   <StartingIndex>0</StartingIndex>
                   <RequestedCount>3</RequestedCount>
                   <SortCriteria>""</SortCriteria>

           </u:Browse>
    </s:Body>
    </s:Envelope>

The response XML that I get does not contain the body content that i require. The response xml is:

    <s:Envelope s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
    <s:Body>
       <s:Fault>
           <faultcode>s:Client</faultcode>
           <faultstring>UPnPError</faultstring>
           <detail>
              <UPnPError>
                  <errorCode>401</errorCode>
                   <errorDescription>Invalid Action</errorDescription>
              </UPnPError>
           </detail>
    </s:Fault>
    </s:Body>
    </s:Envelope>

How do I get the contents of the server.

Solution

Soapaction should be the fully specified identifier of the action you want to call. You are sending a URL to the service description instead. The following should work better:

SOAPACTION: "urn:schemas-upnp-org:service:ContentDirectory:1#Browse"

Your xml may also be invalid, the angle brackets don't seem to match. I would also check the quoting of the Browse argument values: I believe none of them should be quoted.
