在C中解析xml＃

Question

我在努力閱讀這個xml文件作爲朋友列表。 我需要的結果作爲朋友的列表（List<Friend>）其中朋友是

public class Friend 
{ 
    public string UID {get;set;} 
    public string Provider {get;set;} 
    public string PhotoUrl {get;set;} 
    public string ProfileUrl {get;set; 
}

Answer 1

如果你想使用XML序列化，你有兩個選擇：使用類在System.Xml.Serialization命名空間中，並創建一個類結構，它將保存您需要的數據;或者有一個像xsd.exe這樣的工具來爲你生成類。使用前者可以獲得簡明的數據模型，後者可能會獲得比您真正需要的更多的類（自動生成的價格）。

如果你想使用XSD.EXE，你會先救你的XML文件中的（說「file.xml」），然後運行它來創建該文件的架構：

xsd.exe file.xml 

這將創建一個名爲file.xsd的文件，其中包含該XML的架構。然後你XSD.EXE再次運行產生可由XmlSerializer的可用於消費的是XML類：

xsd.exe /c file.xsd

public class FriendList 
    { 
     public List<Friend> friends; 
     public FriendList() 
     { 
     friends= new List<Friend>(); 
     } 
    } 

public class Friend 
{ 
    public string UID {get;set;} 
    public string Provider {get;set;} 
    public string PhotoUrl {get;set;} 
    public string ProfileUrl {get;set;} 
} 

Public class ParseFriends 
{ 
    FriendList p = new FriendList(); 
    public ReadFriends() 
    { 
    DirectoryInfo dir = new DirectoryInfo("../path to your xml file"); 
    FileInfo[] files = dir.GetFiles("*.*"); // read all xml file from a folder 
    XmlDocument doc = new XmlDocument(); 

    foreach (FileInfo f in files) 
      { 
       Friend e = new Friend(); 
       doc.Load(f.FullName); 
       e.UID = doc.GetElementsByTagName("UID")[0].InnerText; 
       e.Provider = doc.GetElementsByTagName("Provider")[0].InnerText; 
       e.PhotoUrl = doc.GetElementsByTagName("PhotoUrl")[0].InnerText; 
       e.ProfileUrl = doc.GetElementsByTagName("ProfileUrl")[0].InnerText; 
       p.empDetails.Add(e); 
      } 
      return p; 
    } 
}

Answer 3

你可以嘗試這樣的事情。

XDocument doc = XDocument.Parse(@" ... XML ... "); 
Func<XElement, string, string> get = 
    (el, name) => (string)el.Element(XName.Get(name, "urn:com:gigya:api")); 
var friends = 
    from el in doc.Descendants(XName.Get("friend", "urn:com:gigya:api")) 
    select new Friend 
     { 
      UID = get(el, "UID"), 
      PhotoUrl = get(el, "photoURL"), 
      ProfileUrl = get(el, "profileURL"), 
     }; 
List<Friend> friendList = friends.ToList();
