How to: Use XML Namespaces in Data Binding

Example

This example shows how to handle namespaces specified in your XML binding 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 xref:System.Windows.Data.XmlNamespaceMapping element to map the namespace to a xref:System.Windows.Data.XmlNamespaceMapping.Prefix%2A, as in the following example. You can then use the xref:System.Windows.Data.XmlNamespaceMapping.Prefix%2A to refer to the XML namespace. The xref:System.Windows.Controls.ListBox in this example displays the title and dc:date of each item.

[!code-xamlXmlnsBindSnippet#XmlNamespaceMapping]

Note that the xref:System.Windows.Data.XmlNamespaceMapping.Prefix%2A 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 xref:System.Windows.Data.XmlNamespaceMapping element also works with inline XML or XML data in an embedded file.
