我使用下面的代碼閱讀XML ..

XDocument xDoc = XDocument.Load("willowcreekassociationblog.wordpress.xml"); 

     var list = xDoc.Descendants("Occurrence") 
     .Select(o => new List.XMLList 
     { 
      title = (string)o.Element("title"), 
      URL = (string)o.Element("link"), 
      Descr = (string)o.Element("Description"), 
      StartDate = (DateTime)o.Element("pubdate"), 
     }) 
     .ToList(); 

但我不知道如何讀的WP：我上面的代碼註釋...有人能幫助我如何做到這一點？

Answer 1

你還沒有說過你想對數據做什麼，這使得問題很難回答。您還沒有表現出wp命名空間別名定義在哪裏，但嘿...

你想要的東西像這個，你Select調用內：

Comments = o.Elements(wp + "comment") 
      .Select(comment => Comment.FromXElement(comment)) 
      .ToList(); 

我發現它有助於給靜可以執行從XElement轉換的域對象中的方法 - 它使事情更清晰。

FromXElement那麼會是這樣的：

public static Comment FromXElement(XElement x) 
{ 
    return new Comment((int) x.Element(wp + "comment_id"), 
         (string) x.Element(wp + "author"), 
         ...); 
}
