在HttpWebResponse使用DOM/SAX代替的XmlSerializer的

Question

我想用SAX/DOM解析器在這下面的代碼讀取HttpWebResponse一個xml 而不是使用XmlSerializer的。
請問我該怎麼做？

HttpWebRequest request = WebRequest.Create(requestURI) as HttpWebRequest; 
    request.Credentials = _cred; 
    WebResponse response = request.GetResponse(); 

    XmlSerializer ser = new XmlSerializer(typeof(MyXMLClass)); 
    myXMLClassObj = ser.Deserialize(response.GetResponseStream()) as MyXMLClass; 

Answer 1

HttpWebRequest request = WebRequest.Create(requestURI) as HttpWebRequest; 
    request.Credentials = _cred; 
    WebResponse response = request.GetResponse();   
System.Xml.XmlDocument doc = new System.Xml.XmlDocument(); 
    doc.Load(response.GetResponseStream()); 

    var elements = doc.GetElementById("myelement"); 

    foreach (var el in elements) 
    { 
     //Do something 
    } 

這是重定向到一個如下的響應和拉動一些元件出來的一個例子。
