例

次の例は、 WriteSubtree ファイルの最初の要素に対してメソッドを使用する方法を示してい book contosoBooks.xml ます。The following example illustrates using the WriteSubtree method on the first book element of the contosoBooks.xml file.

    XPathDocument^ document = gcnew 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();

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();

Dim document As XPathDocument = New XPathDocument("contosoBooks.xml")
Dim navigator As XPathNavigator = document.CreateNavigator()

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

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

writer.Close()

この例は、contosoBooks.xml ファイルを入力として使用します。The example takes the contosoBooks.xml file as an input.

注釈

現在のノードのスコープ内の名前空間の名前空間宣言は、指定されたオブジェクトにストリーミングされる XML に挿入され XmlWriter ます。Namespace declarations for the in-scope namespaces of the current node are inserted into the XML streamed to the XmlWriter object specified.

たとえば、 WriteSubtree ファイルの最初の要素に対してメソッドが呼び出された場合、 book books.xml http://www.contoso.com/books xml ドキュメントの先頭で作成された名前空間宣言は、 XmlWriter 次の例に示すように、指定されたオブジェクトにストリーミングされる xml に表示されます。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"?>
