Question

ASP.NET讀取外部XML我想讀位於here

一個XML文件中的數據看起來像這樣

<profile> 
    <steamID64>76561197967256555</steamID64> 
    <steamID><![CDATA[snivfbo]]></steamID> 
    <onlineState>offline</onlineState> 
    <stateMessage><![CDATA[]]></stateMessage> 
    <privacyState>private</privacyState> 
    <visibilityState>1</visibilityState> 
    <avatarIcon><![CDATA[http://media.steampowered.com/steamcommunity/public/images/avatars/9d/9d13f8f8061b7adaa9e9c2766e2bb2b3d82f911c.jpg]]></avatarIcon> 
    <avatarMedium><![CDATA[http://media.steampowered.com/steamcommunity/public/images/avatars/9d/9d13f8f8061b7adaa9e9c2766e2bb2b3d82f911c_medium.jpg]]></avatarMedium> 
    <avatarFull><![CDATA[http://media.steampowered.com/steamcommunity/public/images/avatars/9d/9d13f8f8061b7adaa9e9c2766e2bb2b3d82f911c_full.jpg]]></avatarFull> 
    <vacBanned>0</vacBanned> 
    <isLimitedAccount>0</isLimitedAccount> 
</profile> 

而我只是希望能夠訪問這些值。我對XmlTextReaders的有限知識已經導致我沒有地方。謝謝。

Answer 1

 XDocument doc = XDocument.Load("http://steamcommunity.com/profiles/76561197967256555/?xml=1"); 
     string steamID64 = doc.Root.Descendants("steamID64").First().Value; 
     string steamID = doc.Root.Descendants("steamID").First().Value; 
     string onlineState = doc.Root.Descendants("onlineState").First().Value; 
     string stateMessage = doc.Root.Descendants("stateMessage").First().Value; 
     string privacyState = doc.Root.Descendants("privacyState").First().Value; 
     string visibilityState = doc.Root.Descendants("visibilityState").First().Value; 
     string avatarIcon = doc.Root.Descendants("avatarIcon").First().Value; 
     string avatarMedium = doc.Root.Descendants("avatarMedium").First().Value; 
     string avatarFull = doc.Root.Descendants("avatarFull").First().Value; 
     string vacBanned = doc.Root.Descendants("vacBanned").First().Value; 
     string isLimitedAccount = doc.Root.Descendants("isLimitedAccount").First().Value;

要獲取XML，請查看HttpWebRequest。使用它在該URL處獲取XML流，然後像jarrett建議的那樣獲取所需的內容，使用Linq獲取所需的數據。

Answer 3

class Program 
{ 
    static void Main(string[] args) 
    { 
     var doc = XDocument.Load("http://steamcommunity.com/profiles/76561197967256555/?xml=1"); 
     foreach (XElement node in doc.Root.Nodes()) 
     { 
      Console.WriteLine("name:{0} | value:{1}", node.Name, node.Value); 
     } 
    } 
}

using System; 
using System.Text; 
using System.Xml.Serialization; 

[Serializable] 
[XmlRoot("profile")] 
public class Profile 
{ 
    [XmlElement("steamID64")] 
    public string SteamId64 { get; set; } 
    [XmlElement("steamID")] 
    public string SteamId { get; set; } 
    [XmlElement("onlineState")] 
    public string OnlineState { get; set; } 
    [XmlElement("stateMessage")] 
    public string StateMessage { get; set; } 
    [XmlElement("privacyState")] 
    public string PrivacyState { get; set; } 
    [XmlElement("visibilityState")] 
    public string VisibilityState { get; set; } 
    [XmlElement("avatarIcon")] 
    public string AvatarIcon { get; set; } 
    [XmlElement("avatarMedium")] 
    public string AvatarMedium { get; set; } 
    [XmlElement("avatarFull")] 
    public string AvatarFull { get; set; } 
    [XmlElement("vacBanned")] 
    public string VacBanned { get; set; } 
    [XmlElement("isLimitedAccount")] 
    public string IsLimitedAccount { get; set; } 

    public override string ToString() 
    { 
     StringBuilder sb = new StringBuilder(); 
     sb.Append("steamID64 : ").Append(this.SteamId64).Append("\n"); 
     sb.Append("steamID : ").Append(this.SteamId).Append("\n"); 
     sb.Append("onlineState : ").Append(this.OnlineState).Append("\n"); 
     sb.Append("stateMessage : ").Append(this.StateMessage).Append("\n"); 
     sb.Append("privacyState : ").Append(this.PrivacyState).Append("\n"); 
     sb.Append("visibilityState : ").Append(this.VisibilityState).Append("\n"); 
     sb.Append("avatarIcon : ").Append(this.AvatarIcon).Append("\n"); 
     sb.Append("avatarMedium : ").Append(this.AvatarMedium).Append("\n"); 
     sb.Append("avatarFull : ").Append(this.AvatarFull).Append("\n"); 
     sb.Append("vacBanned : ").Append(this.VacBanned).Append("\n"); 
     sb.Append("isLimitedAccount : ").Append(this.IsLimitedAccount).Append("\n"); 
     return sb.ToString(); 
    } 
} 

class Program 
{ 
    static void Main(string[] args) 
    { 
     XmlReader reader = new XmlTextReader("http://steamcommunity.com/profiles/76561197967256555/?xml=1"); 

     XmlSerializer xs = new XmlSerializer(typeof(Profile), string.Empty); 
     Profile p = xs.Deserialize(reader) as Profile; 

     Console.WriteLine(p.ToString()); 
    } 
} 

這種方式，你有一個配置文件對象，可以使用屬性訪問其值。
