Working with a xml string [Solved]

C#

I retrieve the source xml of a web page using the following code:

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("url");
            using (Stream stream = request.GetResponse().GetResponseStream())
            {
                using (StreamReader reader = new StreamReader(stream))
                {
                    string response = reader.ReadToEnd();
                }
            }

Usually when working with xml files I would use the following method to read it:

XmlDocument xmlDoc = new XmlDocument();
                        XmlTextReader xmlReader = new XmlTextReader(string.Format(@"{0}\config.xml", pathToConfig));
                        xmlDoc.Load(xmlReader);
                        int NodeNum = 0;
                        if (xmlDoc.ChildNodes[1].ChildNodes.Count > 0)
                        {
                            XmlNode node = null;
                            for (int i = 0; i < xmlDoc.ChildNodes[1].ChildNodes.Count; i++)
                            {
                                node = xmlDoc.ChildNodes[1].ChildNodes[i];
                                if (node.Name.ToString() == "serverIP")
                                {
                                    checkServer = true;
                                    NodeNum = i;
                                    break;
                                }
                            }
                            if (checkServer)
                            {
                                XmlNodeList nodeList = xmlDoc.ChildNodes[1].ChildNodes[NodeNum].ChildNodes;
                                string serverID = nodeList[0].InnerText.ToString();
                            }
                        }

My question is this, how can I modify the above code to work with the returned string from the web, which is basically one long string of xml, rather than with a file. Any help would be appreciated.

It's okay I figured out how to do it I just use LoadXML of the XmlDocument rather than Load.
