code is as follows :
public partial class MainPage: PhoneApplicationPage
{
HttpWebRequest request = null;
HttpWebResponse response = null;
/ / constructor
public MainPage ()
{
InitializeComponent ();
string uri = "http://fpad.ce.cn/hg/news_list.xml" ;

request = (HttpWebRequest) WebRequest.Create (uri);
request.Method = "POST";
request.BeginGetResponse (new AsyncCallback (GetResponseCallBack), null);
}

private void GetResponseCallBack (IAsyncResult ar)
{
List newList = new List ();

response = (HttpWebResponse) request.EndGetResponse (ar);
using (Stream stream = response.GetResponseStream ())
{
StreamReader reader = new StreamReader (stream, new ; Gb2312Encoding ());

using (XmlReader xmlReader = XmlReader.Create ( reader))
{
string title = ; " " ;
string intro = ; " " ;

while (xmlReader.Read ( ) )
{
try
{
if (xmlReader.ReadToFollowing ("a"))
{
title = xmlReader.ReadElementContentAsString ();
}
if (xmlReader.ReadToFollowing ("summary"))
{
intro = xmlReader.ReadElementContentAsString ();
}
}
catch (Exception ex)
{
MessageBox.Show (ex.ToString ());
}

if (title = "!" | |! intro = "")
{
newList.Add (new News {Title = title, Intro = intro});
}
}

} ;
}
Dispatcher.BeginInvoke (() =>
{
NewsList.ItemsSource = newList;
});
}
}

class News
{
public string Title {set; get;}
public string Intro {set; get;}
}

Whatever the title is , every single step debugging to third on the error, that is to say in the first two xml data can be read successfully , the third if (xmlReader.ReadToFollowing (" ; a ")) was catch the
