Xml Transformer

[serkansendur]

I wanted to share my little xml transformer tool that gets xml and xsl input visually and outputs the transformation in a third textbox again visually. i will attach the project so anyone can use it on the fly. i kind of combined the two code snippets from the following two websites :
http://www.knowdotnet.com/articles/indentxml.html
http://www.codeproject.com/KB/cs/xsltrafo.aspx

Transformer.cs :

using System;
using System.IO;
using System.Text;
using System.Xml;
using System.Xml.Xsl;
using System.Xml.XPath;
using System.Windows.Forms;

namespace XMLTransformer
{
	public class Transformer
	{
		public Transformer()
		{
		}

		/// <summary>
		/// transforms XML via XSLTransformation
		/// </summary>
		/// <param name="XMLPage"></param>
		/// <param name="XSLStylesheet"></param>
		/// <returns>The transformed Page</returns>
		public static string Trafo(string XMLPage, string XSLStylesheet, out string ErrMsg)
		{
			//the outputs	
			string result = "";
			ErrMsg = "";

			try
			{
				//read XML
				TextReader tr1 = new StringReader(XMLPage);
				XmlTextReader tr11 = new XmlTextReader(tr1);
				XPathDocument xPathDocument = new XPathDocument(tr11);

				//read XSLT
				TextReader tr2 = new StringReader(XSLStylesheet);
				XmlTextReader tr22 = new XmlTextReader(tr2);
				XslTransform xslt = new XslTransform();
				xslt.Load(tr22);

				//create the output stream
				StringBuilder sb = new StringBuilder();
				TextWriter tw = new StringWriter(sb);

				//xsl.Transform (doc, null, Console.Out);
				xslt.Transform(xPathDocument, null, tw);

				//get result
				result = sb.ToString();
			}
			catch (Exception ex)
			{
				//Console.WriteLine (ex.Message);
				ErrMsg = ex.Message;
			}
			return result;
		}//Trafo

		public static string IndentXMLString(string xml)
		{
			string outXml = string.Empty;
			MemoryStream ms = new MemoryStream();
			// Create a XMLTextWriter that will send its output to a memory stream (file)
			XmlTextWriter xtw = new XmlTextWriter(ms, Encoding.Unicode);
			XmlDocument doc = new XmlDocument();

			try
			{
				// Load the unformatted XML text string into an instance 
				// of the XML Document Object Model (DOM)
				doc.LoadXml(xml);

				// Set the formatting property of the XML Text Writer to indented
				// the text writer is where the indenting will be performed
				xtw.Formatting = Formatting.Indented;

				// write dom xml to the xmltextwriter
				doc.WriteContentTo(xtw);
				// Flush the contents of the text writer
				// to the memory stream, which is simply a memory file
				xtw.Flush();

				// set to start of the memory stream (file)
				ms.Seek(0, SeekOrigin.Begin);
				// create a reader to read the contents of 
				// the memory stream (file)
				StreamReader sr = new StreamReader(ms);
				// return the formatted string to caller
				return sr.ReadToEnd();
			}
			catch (Exception ex)
			{
				MessageBox.Show(ex.ToString());
				return string.Empty;
			}
		}
	}
}

Form1.cs :

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Xml;
using System.Xml.Xsl;
using System.IO;
using System.Xml.XPath;


namespace XMLTransformer
{
	public partial class Form1 : Form
	{
		public Form1()
		{
			InitializeComponent();
		}

		private void button1_Click(object sender, EventArgs e)
		{
			string error = string.Empty;
			try
			{
				textBox1.Text = textBox1.Text.Replace(Environment.NewLine, string.Empty);
				textBox1.Text = Transformer.IndentXMLString(textBox1.Text);
				textBox2.Text = textBox2.Text.Replace(Environment.NewLine, string.Empty);
				textBox2.Text = Transformer.IndentXMLString(textBox2.Text);
				textBox3.Text = Transformer.Trafo(textBox1.Text, textBox2.Text, out error);
			}
			catch (Exception ex)
			{
				MessageBox.Show(ex.Message);
				MessageBox.Show(error);
			}

		}
	}
}

By the way, i was in Manhattan two weeks ago, i would love to visit by Dani to say hi and maybe Julienne Walker if she was around, but i did not have time :)
i think i am no longer as creepy as i used to be :)

Thanks for sharing the transformer tool. I will try these two websites.
