参考 Binding.XPath: http://msdn.microsoft.com/en-us/library/system.windows.data.binding.xpath.aspx
How To Use XPath and an XML Data Island in a WPF Application: http://vbcity.com/blogs/xtab/archive/2010/12/22/how-to-use-xpath-and-an-xml-data-island-in-a-wpf-application.aspx
根据的描述，我做了个例子：
<Window x:Class="WpfApplication3.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Window.Resources> <XmlDataProvider x:Key="XMLData" Source="Data.xml" XPath="Node"/> <DataTemplate DataType="Node"> <TreeViewItem x:Name="item" Header="{Binding XPath=NodeName}"/> <DataTemplate.Triggers> <DataTrigger Binding="{Binding Path=Count, XPath=SubNodes/Node}" Value="0"> <Setter TargetName="item" Property="ItemsSource" Value="{Binding XPath=Params/Param}"/> </DataTrigger> <DataTrigger Binding="{Binding Path=Count, XPath=Params/Param}" Value="0"> <Setter TargetName="item" Property="ItemsSource" Value="{Binding XPath=SubNodes/Node}"/> </DataTrigger> </DataTemplate.Triggers> </DataTemplate> <DataTemplate DataType="Param"> <StackPanel> <TextBlock Text="{Binding XPath=ParamName, StringFormat={}Param Name: {0}}"/> <TextBlock Text="{Binding XPath=ParamDetails, StringFormat={}Param Details: {0}}"/> <TextBlock Text="{Binding XPath=ParamUnits, StringFormat={}Param Units: {0}}"/> <TextBlock Text="{Binding XPath=ParamDefaultValue, StringFormat={}Param Default Value: {0}}"/> <TextBlock Text="{Binding XPath=ParamUserValue, StringFormat={}Param User Value: {0}}"/> </StackPanel> </DataTemplate> </Window.Resources> <Grid> <TreeView ItemsSource="{Binding Source={StaticResource XMLData}}"/> </Grid> </Window>
