讀取RSS時出錯

Question

嘗試讀取ARSTECHNICA RSS供稿時，我不斷收到此錯誤。我收到以下錯誤：

System.Xml.XmlException: '', hexadecimal value 0x10, is an invalid character. Line 96, position 1129.

我知道這是因爲XML中的無效字符，它需要刪除。我確實在查看this以刪除無效的字符。

XmlReader readXML; 
    readXML = XmlReader.Create(URL); 
    SyndicationFeed News= SyndicationFeed.Load(readXML); 
    readXML.Close(); 
    return News; 

我不知道如何從RSS提要中刪除無效字符。有什麼建議麼？

感謝

你可以嘗試加載RSS提要作爲一個字符串，刪除無效字符和負載作爲新聞源。希望有所幫助：

HttpWebRequest httpWebRequest = 
(HttpWebRequest)WebRequest.Create("http://feeds.arstechnica.com/arstechnica/index"); 
HttpWebResponse httpWebesponse = (HttpWebResponse)httpWebRequest.GetResponse(); 

Stream dataStream = httpWebesponse.GetResponseStream(); 
StreamReader streamreader = new StreamReader(dataStream, Encoding.UTF8); 
string response = streamreader.ReadToEnd(); 
streamreader.Close(); 

response = response.Replace((char)0x10, ' '); 

XmlTextReader reader = new XmlTextReader(new System.IO.StringReader(response)); 
reader.Read(); 

SyndicationFeed News = SyndicationFeed.Load(reader);
