Perform an XSL Transform
<source lang="csharp"> using System; using System.Xml; using System.Xml.Serialization; using System.IO; using System.Xml.Xsl;
public class TransformXml {
private static void Main() {
XslTransform transform = new XslTransform();
// Load the XSL stylesheet.
transform.Load("orders.xslt");
// Transform orders.xml into orders.html using orders.xslt.
transform.Transform("orders.xml", "orders.html", null);
}
}
</source>
Read command line input and do the xml xsl translation
<source lang="csharp"> using System; using System.Xml.Xsl; public class Transform {
public static void Main(string [] args) {
string source = args[0];
string stylesheet = args[1];
string destination = args[2];
XslTransform transform = new XslTransform();
transform.Load(stylesheet);
// for .NET v 1.0
//transform.Transform(source, destination);
// for .NET v 1.1
transform.Transform(source, destination, null);
}
}
</source>
Use XslCompiledTransform
<source lang="csharp"> using System; using System.Xml.Xsl; class MainClass {
public static void Main() {
XslCompiledTransform transform = new XslCompiledTransform();
transform.Load("orders.xslt");
transform.Transform("orders.xml", "orders.html");
}
}
</source>
XML transformation: transform XML file to HTML file
<source lang="csharp"> using System; using System.Xml; using System.Xml.Xsl; using System.Xml.XPath; using System.IO;
public class XSLDemo
{
[STAThread]
static void Main(string[] args)
{
XslTransform xslt = new XslTransform();
xslt.Load("XSLTemplate.xsl");
XPathDocument xDoc = new XPathDocument("Books.xml");
XmlTextWriter writer = new XmlTextWriter("Books.html", null);
xslt.Transform(xDoc, null, writer, new XmlUrlResolver());
writer.Close();
StreamReader stream = new StreamReader("Books.html");
Console.Write(stream.ReadToEnd());
}
}
