如何在Silverlight中使用XSLT格式化并输出XML文档

// Load XML Document
XPathDocument xmlXPathDoc = new XPathDocument(HttpContext.Current.Server.MapPath("sample.xml");

// Load XSLT Document
XslCompiledTransform xslTransform = new XslCompiledTransform();

// Add parameters to XSLT Document (optional)
XsltArgumentList xslArg = new XsltArgumentList();
xslArg.AddParam("param1",  string.Empty, "value1");
xslArg.AddParam("param2",  string.Empty, "value2");

// Output
TextWriter writer = new StringWriter();
xslTransform.Transform(xmlXPathDoc, xslArg, writer);
Response.Write(writer.ToString());

HtmlPage.Window.Eval(@ "function transform(xml, xsl)
 {
     var xmlDOM = new ActiveXObject("MSXML2.DOMDocument.6.0");
     xmlDOM.LoadXML(xml);

     xslDOM.LoadXML(xsl);

     return xmlDOM.transformNode(xslDOM);
 }");
