将XML数据绑定到WPF树视图控件

Question

我花了很多时间试图弄清楚如何将我的XML文件中的数据绑定到TreeView控件,但我不知道从哪里开始.我甚至尝试过将Xml数据双向绑定到代码项目上的WPF TreeView和Josh Smith的代码示例,但仍然无法理解如何开始!

我在文件"C:\ SPDependencies.xml"中有XML(如果需要我可以更改格式)!!!:

  <node type="SPDependencies" Name="SPDependencies">
        <node type="StoredProc" Name="SP1">
                <node type="OperationType" Name="Type1">
                        <node type="TableName" Name="Table1"/>
                        <node type="TableName" Name="Table2"/>
                </node>
                <node type="OperationType" Name="Type2">
                         <node type="TableName" Name="Table1"/>
                        <node type="TableName" Name="Table2"/>
                </node>
                 .....
        </node>
        <node type="StoredProc" Name="SP2">
              <node type="OperationType" Name="Type1">
              ...
              ...
        </node>
</node>

我需要以下列格式在Treeview控件中显示它:

<SP1>
   <Type1>
      <Table1>
      <Table2>
      <Table3>
   <Type2>
      <Table1>
      <Table2>
      <Table3>
<SP2>
    <Type1>
........

谢谢,阿比.

给出以下xml文件:

<node type="SPDependencies" Name="SPDependencies">
  <node type="StoredProc" Name="SP1">
    <node type="OperationType" Name="Type1">
      <node type="TableName" Name="Table1"/>
    </node>
    <node type="OperationType" Name="Type2">
      <node type="TableName" Name="Table1"/>
    </node>
  </node>
  <node type="StoredProc" Name="SP2">
    <node type="OperationType" Name="Type1">
    </node>
  </node>
</node>

视图:

<Window x:Class="Tree.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:Tree"
        Title="MainWindow" Height="350" Width="525">
    <Window.DataContext>
        <local:ViewModel />
    </Window.DataContext>
    <Window.Resources>
        <HierarchicalDataTemplate x:Key="template">
            <TextBlock Text="{Binding XPath=@Name}" />
            <HierarchicalDataTemplate.ItemsSource>
                <Binding XPath="node" />
            </HierarchicalDataTemplate.ItemsSource>
        </HierarchicalDataTemplate>
    </Window.Resources>
    <Grid DataContext="{Binding Path=XmlData}">
        <TreeView ItemsSource="{Binding}" ItemTemplate="{StaticResource template}">
        </TreeView>
    </Grid>
</Window>

查看型号:

public class ViewModel
{
    public XmlDataProvider XmlData { get; set; }

    public ViewModel()
    {
        XmlData = new XmlDataProvider();
        XmlData.Source = new Uri(@"C:\input.xml");
        XmlData.XPath = "node";
    }
}

输出:

如果你只是想显示的节点下面的根,只需更改XPath来:

XmlData.XPath = "/node/node";
