c# - Parsing inner tag with its value

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>

I have a Class Chapters class with String and List :

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...

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;
                    }
                }
            }
        }
    }
}

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 ?

How to fix acheive this ?

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...

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();

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; }
}
