XmlNamespaceMapping Class
Assembly: PresentationFramework (in presentationframework.dll)
XML Namespace: http://schemas.microsoft.com/winfx/2006/xaml/presentation
To declare a mapping between a URI and a prefix, create a XmlNamespaceMapping class and add it to a XmlNamespaceMappingCollection object that is used as the XmlNamespaceManager for a binding.
This example shows how to handle namespaces specified in your XMLbinding source.
If your XML data has the following XML namespace definition:
<rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/">
You can use the XmlNamespaceMapping element to map the namespace to a Prefix, as in the following example. You can then use the Prefix to refer to the XML namespace. The ListBox in this example displays the title and dc:date of each item.
<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}" /> <TextBlock Grid.Row="1" Text="{Binding XPath=dc:date}" /> </Grid> </Border> </DataTemplate> </StackPanel.Resources> <ListBox Width="600" Height="600" Background="Honeydew" ItemsSource="{Binding Source={StaticResource provider}}" ItemTemplate="{StaticResource dataTemplate}"/>
Note that the Prefix you specify does not have to match the one used in the XML source; if the prefix changes in the XML source your mapping still works.
In this particular example, the XML data comes from a web service, but the XmlNamespaceMapping element also works with inline XML or XML data in an embedded file.
