问题描述

我有一个这种格式的 plist:

I have a plist in this format:

<plist version="1.0">
<array>
    <dict>
        <key>Title</key>
        <string>Chapters</string>
        <key>Items</key>
        <array>
            <dict>
                <key>Title</key>
                <string>XYZ</string>

            </dict>
            <dict>
                <key>Title</key>
                <string>ABC</string>

            </dict>
              </array>
    </dict>
    <dict>
        <key>Title</key>
        <string>ChaptersONE</string>
        <key>Items</key>
        <array>
            <dict>
                <key>Title</key>
                <string>ASDF</string>

            </dict>
               </array>
    </dict>
</array>

我有一个带有 String 和 List 的 Class Chapters 类:

I have a Class Chapters class with String and List :

我需要这样的:章节包含诸如 XYZ 和 ABC 等子主题的列表......ChaptersONE 包含 ASDF 等子主题列表...

i need it like this: Chapters contains list of subtopics like XYZ and ABC and so on... ChaptersONE contains list of subtopics like ASDF and so on...

现在我已经这样尝试了:

Now i have tried it like this:

XDocument doc = XDocument.Load(FileName);// plist file name
XElement plist = doc.Element("plist");
XElement array = plist.Element("array");

Chapters chapters = null;
String keyValue = String.Empty;

chapters.listOfItems = new List<Chapters>();

using (XmlReader reader = array.CreateReader())
{
    reader.MoveToContent();
    while (reader.Read())
    {
        if (reader.NodeType == XmlNodeType.Element)
        {
            if (reader.Name == "dict")
            {
                chapters = new Chapters();
                listOfItems.Add(chapters);
            }
            else if (reader.Name == "key")
            {
                if (!reader.Read())
                {
                    break;
                }
                else if (reader.NodeType == XmlNodeType.Text || reader.NodeType == XmlNodeType.CDATA)
                {
                    keyValue = reader.Value;
                }
            }
            else if (reader.Name == "string")
            {
                if (!reader.Read())
                {
                    break;
                }
                else if (highwayCode != null && reader.NodeType == XmlNodeType.Text || reader.NodeType == XmlNodeType.CDATA)
                {
                    switch (keyValue)
                    {
                        case "Title":
                            chapters.Header = reader.Value;
                            break;
                        case "Items":
                            break;
                        default:
                            break;
                    }
                }
            }
        }
    }
}

但是我所有的主标题(像 Chapters 和 ChaptersOne 这样的标题)以及子主题都只是分配给字符串，我在这里做错了什么?

But i all the Main title (Headers like Chapters and ChaptersOne) and also the subtopics are just assigning to only the string, what am i doing wrong here ?

如何解决这个问题?

编辑章节应包含 XYZ 和 ABC 等子主题列表...ChaptersONE 应包含 ASDF 等子主题列表...

EDIT Chapters should contains list of subtopics like XYZ and ABC and so on... ChaptersONE should contains list of subtopics like ASDF and so on...

推荐答案

是的，有一个更简单的方法:

Yes, there is an easier way:

XDocument doc = XDocument.Load("input.xml");// plist file name

var chapters = (from d in doc.Root.Element("array").Elements("dict")
                select new Chapter
                {
                    Title = (string)d.Element("string"),
                    SubTitles = d.Element("array")
                                 .Elements("dict")
                                 .Elements("string")
                                 .Select(s => (string)s)
                                 .ToList()
                }).ToList();

你没有展示你的课程，所以我认为它看起来像这样:

You didn't show your classes, so I assumed it looks like that:

class Chapter
{
    public string Title { get; set; }
    public List<string> SubTitles { get; set; }
}
