Property Value

Type: System.Xml.XmlNamespaceManager
The XmlNamespaceManager used to run XPath queries. The default value is null.

Setting the following properties will implicitly cause this XmlDataProvider object to refresh: Source, Document, XmlNamespaceManager, and XPath. When changing multiple refresh-causing properties, the use of DeferRefresh is recommended.

The following example demonstrates how to use this property.

<StackPanel.Resources>
  <XmlNamespaceMappingCollection x:Key="mapping">
    <XmlNamespaceMapping Uri="http://purl.org/dc/elements/1.1/" Prefix="dc" />
  </XmlNamespaceMappingCollection>

  <XmlDataProvider Source="http://msdn.microsoft.com/subscriptions/rss.xml"
                   XmlNamespaceManager="{StaticResource mapping}"
                   XPath="rss/channel/item" x:Key="provider"/>

  <DataTemplate x:Key="dataTemplate">
    <Border BorderThickness="1" BorderBrush="Gray">
      <Grid Width="600" Height="50">
        <Grid.RowDefinitions>
          <RowDefinition Height="25"/>
          <RowDefinition Height="25"/>
        </Grid.RowDefinitions>
        <TextBlock Grid.Row="0" Text="{Binding XPath=title}" />
