How can I fix this?

Question

As a learning resource, I want to convert the Page.Resources and Grid.DataContext to a class structure. Unfortunately I have no idea what route to take. I have looked at the MSDN documentation and found 3 possible ways I could approach this, although each
one confuses me for varous reasons. One, databinding using IObservableCollection<>, two, databinding using the INotifyPropertyChanged interface, and three, creating a class to convert the xml to string objects.
There is also the IValueConverter interface that could be used as well, but I think that is well outside of my current scope of knowledge.
       <Page.Resources>
            <XmlDataProvider x:Key="XmlData"
                       Source="DictionaryData.xml"
                       XPath="WordList/Word"/>
        </Page.Resources>
        <Grid>
            <Grid.DataContext>
                <XmlDataProvider x:Name="XmlData" Source="DictionaryData.xml" XPath="WordList/Word"/>
            </Grid.DataContext>
So far, I have tried using Observable collection and have yielded a result of the C# programming gods telling me NO!
My listbox is completely empty when I run the program.
Here is the code from what i've done so far:
    using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.IO;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;
    using System.Xml.Linq;
    using System.Xml.Serialization;
    namespace EJCReWrite
        public class Data : INotifyPropertyChanged
            private string chinese;
            private string pinyin;
            private string english;
            private const string filePath = @"https://onedrive.live.com/redir?resid=20c5e1cad5eac97f!22900&authkey=!AAjCLv_ozEqrdAY&ithint=file%2cxml";
            public string Chinese
                get
                { return this.chinese; }
                set
                    if (this.chinese != value)
                        this.chinese = value;
                        this.NotifyPropertyChanged("Chinese");
            public string Pinyin
                get { return this.pinyin; }
                set
                    if (this.pinyin != value)
                        this.pinyin = value;
                        this.NotifyPropertyChanged("Pinyin");
            public string English
                get { return this.english; }
                set
                    if (this.english != value)
                        this.english = value;
                        this.NotifyPropertyChanged("English");
            public event PropertyChangedEventHandler PropertyChanged;
            public void NotifyPropertyChanged(string propName)
                if (this.PropertyChanged != null)
                    this.PropertyChanged(this, new PropertyChangedEventArgs(propName));
            public void deserializeXML()
                if (File.Exists(filePath))
                    XmlSerializer deserializer = new XmlSerializer(typeof(Data));
                    TextReader reader = new StreamReader(filePath);
                    object obj = deserializer.Deserialize(reader);
                    Data XmlData = (Data)obj;
                    reader.Close();
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;
    using System.Windows;
    using System.Windows.Controls;
    using System.Windows.Data;
    using System.Windows.Documents;
    using System.Windows.Input;
    using System.Windows.Media;
    using System.Windows.Media.Imaging;
    using System.Windows.Navigation;
    using System.Windows.Shapes;
    using System.ComponentModel;
    using System.Collections.ObjectModel;
    using System.Xml.Linq;
    namespace EJCReWrite
        /// <summary>
        /// Interaction logic for MainWindow.xaml
        /// </summary>
        public partial class MainWindow : Window
            private ObservableCollection<Data> calledData = new ObservableCollection<Data>();
            public MainWindow()
                InitializeComponent();
                Data data = new Data();
                data.deserializeXML();
                listBox.ItemsSource = data.Chinese;
    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <!--This is a generated XML File-->
    <WordList>
      <Word>
        <English>able</English>
        <Pinyin>Néng</Pinyin>
        <Chinese>能</Chinese>
      </Word>
      <Word>
        <English>aboard</English>
        <Pinyin>Chuánshàng</Pinyin>
        <Chinese>船上</Chinese>
      </Word>
      <Word>
        <English>about</English>
        <Pinyin>Dàyuē</Pinyin>
        <Chinese>大约</Chinese>
      </Word>
      <Word>
        <English>above</English>
        <Pinyin>Yǐshàng</Pinyin>
        <Chinese>以上</Chinese>
      </Word>
      <Word>
        <English>accept</English>
        <Pinyin>Jiēshòu</Pinyin>
        <Chinese>接受</Chinese>
      </Word>
      </WordList>
So, as it stands right now, I am at a loss for what I am doing wrong with the code. Any pointers (ha! I crack myself up with puns) in the right direction would be greatly appreciated.

Hello Sozee and welcome to the BlackBerry Support Community Forums.
Sorry to hear you're having an issue downloading applications.
Did you check the requirement at www.blackberry.com/blackberryworld for each application to ensure your device model, software version, mobile service provider and country of origin are all met?
Can you provide the name of one the apps in question? Who's your mobile provider? In what country do you live?
Thanks!
