Then save whole xml locally over there and then read it in dataset that's all.

Sounds like you answered your own question. Create a serialization class that knows what each of the records looks like that will create an NSString containing the xml that holds the data from your NSData object. You can the append that into the appropriate part of the envelope body and call the service that way.

Pseudo Code:

public class MyDataSerialization
{
 /* maybe static, depends on you */
    public string TurnDataToXml(NSData theData)
    {
      /* maybe static, depends on you */
        foreach (dataUnit in theData)
        {
            //create the appropriate xml nodes in a string you are returning
        }
    return myStringOfXmlNodes;
    }
}

I haven't looked at it yet, but another idea is to use the NSXml object to create your entire envelope programmatically. This is probably the better option as it is specific to what we are trying to do. Using the static strings above is just a simple way to show what we are all trying to accomplish. You can abstract the hell out of what's up there and make it as complex as you like.

Here's some more info about the NSXml object.

Here's the wiki article about serialization. It even has an Objective-C sample (though it looks like they are talking about binary serialization as opposed to xml).
