It’s not superior in any way to the SharePoint web part, but I don’t have the source for the SharePoint web part just laying around either. The code uses the XslCompiledTransform class to transform the xml provided.

using System.Xml.Xsl;

public class XMLWebPart : WebPart
{
[Personalizable, Browsable(true),WebBrowsable(true),Description("Url of Source XML Document")]
public string SourceURL
{
get
{
return (string)ViewState["XmlURL"];
}
set
{
ViewState["XmlURL"] = value;
}
}

public string Document

}
protected override void RenderContents(System.Web.UI.HtmlTextWriter writer)
{
try
{
// get the style sheet
string transformDocument = (!string.IsNullOrEmpty(StyleSheetURL)) ? Utility.GetWebTextFile(Page.ResolveUrl(StyleSheetURL)) : StyleSheet;
// get the xml
string xmlDoc = (!string.IsNullOrEmpty(SourceURL)) ? Utility.GetWebTextFile(Page.ResolveUrl(SourceURL)) : Document;
writer.Write(string.Format("<div id={0}>", UniqueID));
// if we have a style sheet use it to transform the xml
if (!string.IsNullOrEmpty(transformDocument) && !string.IsNullOrEmpty(xmlDoc))
{
XslCompiledTransform transform = new XslCompiledTransform();
transform.Load(XmlReader.Create(new StringReader(transformDocument)));
transform.Transform(XmlReader.Create(new StringReader(xmlDoc)), XmlWriter.Create(writer));
}
else if (!string.IsNullOrEmpty(xmlDoc))
{
writer.Write(xmlDoc);
}
writer.Write("</div>");
}
catch (System.Xml.XmlException)
{
writer.Write("XML error");
}
catch (Exception exception)

Debug.WriteLine(exception.ToString());
