    body.stringValue = message;
    NSXMLElement *msg = [NSXMLElement elementWithName:@"message"];
    [msg addAttributeWithName:@"type" stringValue:@"chat"];
    NSString *to = [NSString stringWithFormat:@"%@@shenqi",user];
    [msg addAttributeWithName:@"to" stringValue:to];
    [msg addChild:body];
    [_xmppStream sendElement:msg];

}

    NSString *messageBody =  [message elementsForName:@"body"][0];
    NSLog(@"messageBody = %@",messageBody);
