MikeWo declared March 8-14 "CodeShareWeek." my code-mate, CarpDeus posted a few things and i finally figured i'd join in, too.

so here's my contribution to CodeShareWeek. it's an XSLT helper class. i do lots of work w/ XSLT and get tired of rewriting the same functions. over time, i've tweaked this class to do things like:

• Cache the XmlDocument
• Cache the XslCompiledTransform class
• Return results as a MemoryStream or as a String (XmlDocument + StringWriter = EVIL)
• Properly handle BOM (byte-order marks are evil, dangit!)
• Use XPathNavigator for fast transforms

here's couple examples of my Xslt.cs class in action:

Amundsen.Utilities.Xslt xslt = new Amundsen.Utilities.Xslt();

System.Xml.Xsl.XsltArgumentList XsltArgs = new System.Xml.Xsl.XsltArgumentList();
XsltArgs.AddParam("run-date", "", System.DateTime.Now);

// test #1
Console.Out.WriteLine("*** using two paths");
Console.Out.Write(xslt.Transform(args[0], args[1], XsltArgs));

// test #2
Console.Out.WriteLine("\n*** using memory stream");
System.IO.MemoryStream ms = new System.IO.MemoryStream();
xslt.Transform(args[0], args[1], XsltArgs, ms);
using (System.IO.StreamReader sr = new System.IO.StreamReader(ms))
{
  Console.Out.Write(sr.ReadToEnd());
  sr.Close();
}

there are a lot more options. you can download the source code and a sample app from my Codeplex space. feel free to leave me feedback there, too.

oh, yeah. thanks to MikeWo for the cool idea!
