XPathNavigator.WriteSubtree Method

Note: This method is new in the .NET Framework version 2.0.

Streams the current node and its child nodes to the XmlWriter object specified.

Namespace: System.Xml.XPath
Assembly: System.Xml (in system.xml.dll)

public virtual void WriteSubtree (
	XmlWriter writer
)
public void WriteSubtree (
	XmlWriter writer
)
public function WriteSubtree (
	writer : XmlWriter
)

Parameters

writer

The XmlWriter object to stream to.

Return Value

An XmlWriter object that contains the current node and its child nodes.

Namespace declarations for the in-scope namespaces of the current node are inserted into the XML streamed to the XmlWriter object specified.

For example, if the WriteSubtree method is called on the first book element of the books.xml file, the http://www.contoso.com/books namespace declaration made at the top of the XML document will appear in the XML streamed to the XmlWriter object specified as shown in the following example.

<?xml version="1.0" encoding="utf-8"?>
<book genre="autobiography" publicationdate="1981" ISBN="1-861003-11-0" xmlns="http://www.contoso.com/books">
    <title>The Autobiography of Benjamin Franklin</title>
    <author>
        <first-name>Benjamin</first-name>
        <last-name>Franklin</last-name>
    </author>
    <price>8.99</price>
</book>
NoteNote

The WriteSubtree method does not affect the position of the XPathNavigator.

The following example illustrates using the WriteSubtree method on the first book element of the contosoBooks.xml file.

XPathDocument document = new XPathDocument("contosoBooks.xml");
XPathNavigator navigator = document.CreateNavigator();

navigator.MoveToChild("bookstore", "http://www.contoso.com/books");
navigator.MoveToChild("book", "http://www.contoso.com/books");

XmlWriter writer = XmlWriter.Create("contosoBook.xml");
navigator.WriteSubtree(writer);

writer.Close();

The example takes the contosoBooks.xml file as an input.
