Question

我正在搜索几个小时，我正在尝试将XML文件绑定到treeView。通常，我想在ListBox中选择XML文件，在树视图中打开XML文件。

XML看起来像这样：

<test>
  <communication>
    <global>
      <server id="Server" ip="172.17.10.50" port="5072" />
    </global>
    <devices>
      <device id="Server" ip="172.18.100.50" port="3451" />
      <device id="cInterface" ip="172.17.12.52" port="3567" />
      <device id="caServer" ip="172.17.12.52" port="3000" />
    </devices>
    <groups>
      <group id="group_cInterface">
        <device id="cInterface" />
        <device id="Server" />
      </group>
    </groups>
  </communication>
</test>

非常感谢。如果需要我的全部代码，请随时提问！

可以达到此输出： Output

使用此XAML代码：

<Window x:Class="Communication.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="693.55" Width="780">

<Window.Resources>
    <HierarchicalDataTemplate x:Key="NodeTemplate"
        ItemsSource="{Binding XPath=./*}">
        <TextBlock x:Name="nodetext"/>
        <HierarchicalDataTemplate.Triggers>
            <DataTrigger Binding="{Binding Path=NodeType}"
                Value="Element">
                <Setter TargetName="nodetext" Property="Text"
                    Value="{Binding Path=Name}" />
            </DataTrigger>
        </HierarchicalDataTemplate.Triggers>
    </HierarchicalDataTemplate>
</Window.Resources>

<Grid>
    <Button Content="loadData" HorizontalAlignment="Left" Height="31" Margin="10,246,0,0" VerticalAlignment="Top" Width="63" Click="Button_Click"/>
    <ListBox x:Name="listBoxKonsole" HorizontalAlignment="Left" Height="214" Margin="10,27,0,0" VerticalAlignment="Top" Width="752" SelectionChanged="listBoxKonsole_SelectionChanged" />
    <TreeView x:Name="treeView" Height="214" Margin="10,282,0,0" Width="752"  ItemTemplate="{StaticResource NodeTemplate}"
        HorizontalAlignment="Stretch"
        VerticalAlignment="Stretch"
        ItemsSource="{Binding}"
        VirtualizingStackPanel.IsVirtualizing="False"
        VirtualizingStackPanel.VirtualizationMode="Standard" />

</Grid>
</Window>

和这段代码：

public void listBoxKonsole_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {          

        // Get the file's location.
        string filename = listBoxKonsole.SelectedItem.ToString();

        // Make an XmlDataProvider that uses the file.
        XmlDataProvider provider = new XmlDataProvider();
        provider.Source = new Uri(filename, UriKind.Absolute);
        provider.XPath = "./*";

        // Make the TreeView display the XmlDataProvider's data.
        treeView.DataContext = provider;



    }

现在我的Pproblem是我还要显示xml属性而不仅仅是XML节点名称。属性可以在一行中与节点的名称，但我不知道如何实现它。

谢谢

我为这样的XML文档创建了一个TreeView。 XAML：

<Window.Resources>
    <DataTemplate x:Key="AttributeTemplate">
        <StackPanel Orientation="Horizontal"
        Margin="3,0,0,0"
        HorizontalAlignment="Center">
            <TextBlock Text="{Binding Path=Name}" />
            <TextBlock Text="=&quot;" />
            <TextBlock Text="{Binding Path=Value, Mode=TwoWay}" />
            <TextBlock Text="&quot;" />
        </StackPanel>
    </DataTemplate>

    <HierarchicalDataTemplate x:Key="NodeTemplate">
        <StackPanel Orientation="Horizontal" Focusable="False">
            <TextBlock x:Name="tbName" Text="Root" FontFamily="Consolas" FontSize="8pt" />
            <ItemsControl
        ItemTemplate="{StaticResource AttributeTemplate}" HorizontalAlignment="Center"
        ItemsSource="{Binding Converter={StaticResource AttrConverter}}">
                <ItemsControl.ItemsPanel>
                    <ItemsPanelTemplate>
                        <StackPanel Orientation="Horizontal" />
                    </ItemsPanelTemplate>
                </ItemsControl.ItemsPanel>
            </ItemsControl>
        </StackPanel>
        <HierarchicalDataTemplate.ItemsSource>
            <Binding Path="Elements" />
        </HierarchicalDataTemplate.ItemsSource>
        <HierarchicalDataTemplate.Triggers>
            <DataTrigger Binding="{Binding Path=NodeType}" Value="Element">
                <Setter TargetName="tbName" Property="Text" Value="{Binding Path=Name}" />
            </DataTrigger>
            <DataTrigger Binding="{Binding Path=FirstNode.NodeType}" Value="Text">
                <Setter TargetName="tbName" Property="Text">
                    <Setter.Value>
                        <MultiBinding StringFormat="{}{0} = {1}">
                            <Binding Path="Name"/>
                            <Binding Path="FirstNode.Value"/>
                        </MultiBinding>
                    </Setter.Value>
                </Setter>
            </DataTrigger>
        </HierarchicalDataTemplate.Triggers>
    </HierarchicalDataTemplate>
</Window.Resources>
...
<TreeView x:Name="LizenzAnsicht"
                      ItemsSource="{Binding Path=Root.Elements, UpdateSourceTrigger=PropertyChanged}"
                      ItemTemplate="{StaticResource ResourceKey=NodeTemplate}"
                      />

XML与XDocument（linq）一起使用，只是设置为TreeView的DataSource。
