Subject: Send query.
Hello everyone.
How I can send query width this xml for example:

<iq type='get'>
 <query xmlns='...'>
   <methodCall>
     <methodName>getStopName</methodName>
     <params>
       <param><value><string>somestring</string></value></param>
       <param><value><i4>3</i4></value></param>
     </params>
   </methodCall>
  </query>
</iq>

I use the agsXMPP.protocol.client.IQ class:

IQ myIq=new IQ(IqType.get);
myIq.Query.SetTag("MethodCall");
//send this query
con.Send(myIq);

How paste other elements in <methodCall> element, such as <methodName>,<params>...?

I think what you are looking for is XEP-0009 Jabber-RPC. This is already included with agsXMPP.

Alex, please help me build a typical request with agsxmpp:

<iq type='set'
    from='requester@company-b.com/jrpc-client'
    to='responder@company-a.com/jrpc-server'
    id='rpc1'>
  <query xmlns='jabber:iq:rpc'>
    <methodCall>
      <methodName>examples.getStateName</methodName>
      <params>
        <param>
          <value><i4>6</i4></value>
        </param>
      </params>
    </methodCall>
  </query>
</iq>

Thank you.
I send correct query now. But response incoming with error:

<error xmlns="jabber:client" code="501" type="cancel"><feature-not-implemented xmlns="urn:ietf:params:xml:ns:xmpp-stanzas" /></error>

What means this error?

please post the complete request including the complete response.
feature-not-implemented means that the receiver of this IQ does not support this protocol or namespace.

I write this code for get all values:

                    Rpc rpc = new Rpc();
                    rpc = (Rpc)iq.Query;
                    MethodResponse resp = new MethodResponse();
                    resp = rpc.MethodResponse;
                    ArrayList arr = resp.GetResponse();
Response:

<methodResponse>
 <params>
   <param>
     <value><i4>5</i4></value>
   </param>
   <param>
     <value><string>string_1</string></value>
     <value><string>string_2</string></value>
     <value><string>string_3</string></value>
   </param>
 </params>
</methodResponse>

In array list writed <5> and <string_1>.
 What I do not correctly?

I find bug in your library. It was in MethodResponse.ParseResponse.
Look at part code where bug:

        private ArrayList ParseResponse()
        {
           ...
                //incorrect code I place in comment
                foreach (Element p in nl)
                {
                    //Element value = p.SelectSingleElement("value");
                    //if (value != null)
                    //    al.Add(ParseValue(value));

                    //correct
                    ElementList list = p.SelectElements("value");
                    for (int i = 0; i < list.Count; i++)
                    {
                        al.Add(ParseValue(list.Item(i)));
                    }
                }
            }
            return al;
        }

Good luck.

no, IMHO your response is wrong according to the XML-RPC specs. If you want to return a string array you have to embed it in a data element.
See: http://www.xmlrpc.com

Alex, I agree with you but I needed to make it just like that.
Now I have question again:
Application is receiving different types of responses which must have to processed differently.
How to know in what way I must process response?
I read your document "creating own packet types" but if I will use this method then I will need to refuse from xml rpc standard of packet.
What will way be better?

I would use jabber:iq:rpc only if you have to reuse or integrate with existing rpc code and services.

Hi.
I read your document "creating own packet types" and want to write class for getting informations from iq like this:
  1. <iq type="result" id="111" to="some">
  2.    <query xmlns="someNamespace">
  3.       <methodResponse>
  4.          <params>
  5.            <param>
  6.              <value><i4>7</i4></value>
  7.           </param>
  8.          <param>
  9.          <value>
  10.              <array>
  11.                 <data>
  12.                   <value><i4>-1</i4></value>
  13.                    <value><i4>1</i4></value>
  14.                </data>
  15.             </array>
  16.         </value>
  17.        </param>
  18.        <param>
  19.         <value>
  20.          <array>
  21.           <data>
  22.             <value><string>one</string></value>
  23.             <value><string>two</string></value>
  24.           </data>
  25.         </array>
  26.       </value>
  27.    </param>
  28. </params>
  29. </methodResponse>
  30. </query>
  31. </iq>

In document "creating own packet types" you did it for this xml

  1. <message xmlns="jabber:client" to="romeo@montage.net">
  2.  <weather xmlns="agsoftware:weather">  
  3. <humidity>90</humidity>
  4.  <temperature>57</temperature>  
  5. </weather>
  6.  </message>
there is no elements with type of param, only name of param.
How do it without names, but with types?
Please, help me write this class.

to me it looks like you want to add RPC. This is already in the SDK in the agsXMPP.protocol.iq.rpc namespace.

Yes, I successfully send any query using agsXMPP.protocol.iq.rpc.
 Now I take respose:

                                Rpc rpc = new Rpc();
                                rpc = (Rpc)iq.Query;
                                MethodResponse resp = new MethodResponse();
                                resp = rpc.MethodResponse;
                                ArrayList arr = resp.GetResponse();

But then I must correct processed arr. To do it I  must know what packed incoming.
And I know that it was like this

   1.
      <iq type="result" id="111" to="some">
   2.
         <query xmlns="someNamespace">
   3.
            <methodResponse>
   4.
               <params>
   5.
                 <param>
   6.
                   <value><i4>7</i4></value>
   7.
                </param>
   8.
               <param>
   9.
               <value>
  10.
                   <array>
  11.
                      <data>
  12.
                        <value><i4>-1</i4></value>
  13.
                         <value><i4>1</i4></value>
  14.
                     </data>
  15.
                  </array>
  16.
              </value>
  17.
             </param>
  18.
             <param>
  19.
              <value>
  20.
               <array>
  21.
                <data>
  22.
                  <value><string>one</string></value>
  23.
                  <value><string>two</string></value>
  24.
                </data>
  25.
              </array>
  26.
            </value>
  27.
         </param>
  28.
      </params>
  29.
      </methodResponse>
  30.
      </query>
  31.
      </iq>


or like this

<iq type="result" id="111" to="some">

<query xmlns="someNamespace">
<methodResponse>

<params><param>

<value><boolean>1</boolean></value>

</param></params>

</methodResponse></query></iq>

How I may to know what in query?

Thank you.
