我正在开发Windows Phone 8应用程序。

我有一个像下面这样的xml:

<array>
    <dict>
        <key>SubTopics</key>
        <array>
            <dict>
                <key>ID</key>
                <array>
                    <string>CD1</string>
                    <string>CD2</string>
                    <string>CD3</string>
                    <string>CD4</string>    
                </array>
                <key>Title</key>
                <string>Miscellaneous</string>
                <key>Desc</key>
                <string> this is just a text</string>
                <key>HasItems</key>
                <true/>
            </dict>
            <dict>
                <key>ID</key>
                <array>
                    <string>DDC1</string>
                    <string>DDC2</string>
                    <string>DDC3</string>
                    <string>DDC4</string>
                    <string>DDC5</string>
                </array>
                <key>Title</key>
                <string>Miscellaneous One</string>
                <key>Desc</key>
                <string> this is just a text</string>
                <key>HasItems</key>
                <true/>
            </dict>
      </array>
      <key>MainTitle</key>
      <string>Data</string>
    </dict>
    <dict>
        <key>SubTopics</key>
        <array>
            <dict>
                <key>ID</key>
                <array>
                    <string>SSD1</string>
                    <string>SS2</string>
                    <string>SS3</string>
                    <string>SS4</string>    
                </array>
                <key>Title</key>
                <string>Goblins</string>
                <key>Desc</key>
                <string> this is just a text</string>
                <key>HasItems</key>
                <true/>
            </dict>
            <dict>
                <key>ID</key>
                <array>
                    <string>ADC1</string>
                    <string>ADC2</string>
                    <string>ADC3</string>
                    <string>ADC4</string>
                    <string>DDC5</string>
                </array>
                <key>Title</key>
                <string>Tracks</string>
                <key>Desc</key>
                <string> this is just a text</string>
                <key>HasItems</key>
                <true/>
            </dict>
      </array>
      <key>MainTitle</key>
      <string>Data Two</string>
    </dict>
</array>

如何解析这个?

就像这样:

MainTitle 

   --SubTitle // list of title 

  ---ID

  ---Desc

  ---Boolean Value
 MainTitle 

   --SubTitle //list of values

  ---ID

  ---Desc

  ---Boolean Value

现在在第一个屏幕中,我显示所有主要标题

现在点击第一个屏幕中的主要图块,我需要该主标题的所有值。

那我怎样才能存储这些Dictionary<string, List<MyObject>>

修改

我试过这个:

var dict = (from plist in doc.Root.Element("array").Elements("dict")
                          select new MyObject
                          {
                              MainTitle = (string)plist.Element("string"),
                              ListOfSubTitles = plist.Element("array")
                                                   .Elements("dict")
                                                   .Elements("string")
                                                   .Select(s => (string)s)
                                                   .ToList(),
                          })
                         .ToDictionary(a => a.MainTitle, a => a.ListOfSubTitles);

但是这里它也在ListOfSubTitles

中存储了Desc标签值

答案 0 :(得分:1)

我建议使用辅助方法。第一个是从您的奇怪的xml数据格式创建值的字典(它使用key元素值作为字典条目键,下一个节点作为字典条目值):

static Dictionary<string, XElement> GetValues(XElement dict)
{
    return dict.Elements("key")
               .ToDictionary(k => (string)k, k => (XElement)k.NextNode);
}

第二个是解析MyObject

static MyObject ParseMyObject(XElement dict)
{
    var values = GetValues(dict);

    return new MyObject
    {
        MainTitle = (string)values["Title"],
        ListOfSubTitles = values["ID"].Elements().Select(s => (string)s).ToList()
    };
}

所有解析都将如下所示:

XDocument xdoc = XDocument.Load(path_to_xml);
var result = 
    xdoc.Root.Elements("dict")
        .Select(GetValues)
        .ToDictionary(v => (string)v["MainTitle"],
                      v => v["SubTopics"]
                              .Elements("dict").Select(ParseMyObject).ToList());

解析结果:

{
  "Data": [
    {
      MainTitle: "Miscellaneous",
      ListOfSubTitles: [ "CD1", "CD2", "CD3", "CD4" ]
    },
    {
      MainTitle: "Miscellaneous One",
      ListOfSubTitles: [ "DDC1", "DDC2", "DDC3", "DDC4", "DDC5" ]
    }
  ],
  "Data Two": [
    {
      MainTitle: "Goblins",
      ListOfSubTitles: [ "SSD1", "SS2", "SS3", "SS4" ]
    },
    {
      MainTitle: "Tracks",
      ListOfSubTitles: [ "ADC1", "ADC2", "ADC3", "ADC4", "DDC5" ]
    }
  ]
}
