Examples

En el ejemplo siguiente se carga y edita un documento XML antes de realizar una transformación XSLT.The following example loads and edits an XML document before performing an XSLT transform.

XmlDocument^ doc = gcnew XmlDocument;
doc->Load( "books.xml" );

// Modify the XML file.
XmlElement^ root = doc->DocumentElement;
root->FirstChild->LastChild->InnerText = "12.95";

// Create an XPathNavigator to use for the transform.
XPathNavigator^ nav = root->CreateNavigator();

// Transform the file.
XslTransform^ xslt = gcnew XslTransform;
xslt->Load( "output.xsl" );
XmlTextWriter^ writer = gcnew XmlTextWriter( "books.html", nullptr );
xslt->Transform( nav, nullptr, writer, nullptr);
XmlDocument doc = new XmlDocument();
doc.Load("books.xml");

// Modify the XML file.
XmlElement root = doc.DocumentElement;
root.FirstChild.LastChild.InnerText = "12.95";

// Create an XPathNavigator to use for the transform.
XPathNavigator nav = root.CreateNavigator();

// Transform the file.
XslTransform xslt = new XslTransform();
xslt.Load("output.xsl");
XmlTextWriter writer = new XmlTextWriter("books.html", null);
xslt.Transform(nav, null, writer, null);
Dim doc as XmlDocument = new XmlDocument()
doc.Load("books.xml")

' Modify the XML file.
Dim root as XmlElement = doc.DocumentElement
root.FirstChild.LastChild.InnerText = "12.95"

' Create an XPathNavigator to use for the transform.
Dim nav as XPathNavigator = root.CreateNavigator()

' Transform the file.
Dim xslt as XslTransform = new XslTransform()
xslt.Load("output.xsl")
Dim writer as XmlTextWriter = new XmlTextWriter("books.html", nothing)
xslt.Transform(nav,nothing, writer, nothing)

Remarks

El XPathNavigator proporciona acceso aleatorio de solo lectura a los datos.The XPathNavigator provides read-only, random access to data. Dado que está optimizado para las transformaciones XSLT, proporciona ventajas de rendimiento cuando se usa como mecanismo de entrada para el método XslTransform.Transform.Because it is optimized for XSLT transformations, it provides performance benefits when used as an input mechanism to the XslTransform.Transform method.

Este método es una extensión de Microsoft para el Document Object Model (DOM).This method is a Microsoft extension to the Document Object Model (DOM).
