. Чистый читатель XML не обнаруживает всех узлов

Я не могу заставить читателя .NET XML сотрудничать во всем. Вот мой код:. Чистый читатель XML не обнаруживает всех узлов

public void downloadfile(string reqURL) 
{ 
    HttpWebRequest webreq = (HttpWebRequest)WebRequest.Create(reqURL); 
    // Set some reasonable limits on resources used by this request 
    webreq.MaximumAutomaticRedirections = 4; 
    webreq.MaximumResponseHeadersLength = 4; 
    //==================== 
    // Set credentials to use for this request. 
    webreq.Credentials = CredentialCache.DefaultCredentials; 
    HttpWebResponse response = (HttpWebResponse)webreq.GetResponse(); 
    //==================== 
    // Get the stream associated with the response. 
    XMLStream = response.GetResponseStream(); 
    Console.WriteLine("Response gotten"); 
    readStream = new StreamReader(XMLStream, Encoding.UTF8); 

    XmlReaderSettings settings = new XmlReaderSettings(); 
    settings.ConformanceLevel = ConformanceLevel.Fragment; 
    settings.IgnoreWhitespace = true; 
    settings.IgnoreComments = true; 
    XmlReader reader = System.Xml.XmlReader.Create(readStream, settings); 

    String title; 
    String link; 
    String descrip; 
    int cut; 
    for (; ;) 
    { 
     //get data 
     reader.ReadToFollowing("title"); 
     title = reader.ReadInnerXml(); 
     reader.ReadToFollowing("link"); 
     link = reader.ReadInnerXml(); 
     reader.ReadToFollowing("description"); 
     descrip = reader.ReadInnerXml(); 
     //check if end of file. 
     if (reader.EOF == true) { break; } 
     if (title != "SimpleVoiceCenter message") 
     { 
      String istribox; 
      istribox = descrip.Substring(0, 20); 
      if 
       (
       istribox != "Voicebox number: 99." && 
       istribox != "Voicebox number: 88." && 
       istribox != "Voicebox number: 77." 
       ) 
      { 
       //Title ===== 
       Console.WriteLine("title: " + title); 
       //Link ===== 
       Console.WriteLine("link: ..."); 
       //Descrip ===== 
       cut = descrip.IndexOf("."); 
       if (cut < 0) 
       { 
        cut = 20; 
       } 
       descrip = descrip.Remove(cut); 
       if (descrip.EndsWith(".")) 
       { 
        descrip = descrip.Remove(cut - 1); 
       } 
       descrip = descrip.Replace("Voicebox number: ", "     "); 
       descrip = descrip.Trim(); 
       Console.WriteLine("voicebox: " + descrip); 
       Console.WriteLine(""); 
      } 
      else { Console.WriteLine("skipping tribox"); } 
     } else { Console.WriteLine("skipping title");} 
    } 
}

Возможно, вам стоит попытаться объяснить, что именно вы пытаетесь прочитать из этого файла RSS и каков ожидаемый результат. –

(продолжение комментария Дарина) ... выделение, где фактический отличается от ожидаемого –

Зачем использовать XML-сериализацию для того, что это такое. Перемещение по узлам не похоже на правильный способ справиться с этим. Попробуйте создать класс для информации, необходимой (быстрый макет):

[Serializable] 
[XmlRoot("rss")] 
public class MyRss 
{ 
    [XmlAttribute("version")] 
    public string Version { get; set; } 

    [XmlElement("channel")] 
    public Channel Channel { get; set; } 

    ... 
} 

[Serializable] 
public class Channel 
{ 
    [XmlElement("version")] 
    public string Title { get; set; } 

    [XmlArrayItem("item")] 
    public List<Item> Items { get; set; } 

    ... 
}

, а затем десериализации строки в этот класс и использовать, чтобы создать свой вывод:

public static MyRss Deserialize(string xmlString) 
{ 
    var obj = new XmlSerializer(typeof(MyRss)).Deserialize(new StringReader(xmlString)); 
    return (MyRss)obj; 
}

затем использовать объект для вывода того, что вам нужно.

Надеюсь, это поможет!

После большего исследования, я думаю, что это то, что я буду делать. –

Для анализа и чтения XML LinqToXml является отличным улучшением по сравнению с XmlReader.

. Чистый читатель XML не обнаруживает всех узлов
