Remarks

The XmlXapResolver is the default resolver for the XDocument , XmlReader and the XmlReaderSettings.

Examples

The following example loads an XML file from your application's XAP file.

Dim output As StringBuilder = New StringBuilder()

' XmlXapResolver is the default resolver. 
Using reader As XmlReader = XmlReader.Create("book.xml")

    ' Moves the reader to the root element.
    reader.MoveToContent()

    reader.ReadToFollowing("book")
    ' Note that ReadInnerXml only returns the markup of the node's children
    ' so the book's attributes are not returned.
    output.AppendLine("Read the first book using ReadInnerXml...")
    output.AppendLine(reader.ReadInnerXml())

    reader.ReadToFollowing("book")

    ' ReadOuterXml returns the markup for the current node and its children
    ' so the book's attributes are also returned.
    output.AppendLine("Read the second book using ReadOuterXml...")
    output.AppendLine(reader.ReadOuterXml())
End Using

OutputTextBlock.Text = output.ToString()

StringBuilder output = new StringBuilder();

// XmlXapResolver is the default resolver.
using (XmlReader reader = XmlReader.Create("book.xml"))
{
    // Moves the reader to the root element.
    reader.MoveToContent();

    reader.ReadToFollowing("book");
    // Note that ReadInnerXml only returns the markup of the node's children
    // so the book's attributes are not returned.
    output.AppendLine("Read the first book using ReadInnerXml...");
    output.AppendLine(reader.ReadInnerXml());

    reader.ReadToFollowing("book");

    // ReadOuterXml returns the markup for the current node and its children
    // so the book's attributes are also returned.
    output.AppendLine("Read the second book using ReadOuterXml...");
    output.AppendLine(reader.ReadOuterXml());

}

OutputTextBlock.Text = output.ToString();

The example uses bool.xml file as input.
