Ever had badly formatted XML that you wanted to have looking clean? Here is a little bit of C# that cleans up the XML indentation and makes a pretty printed XML for you.

using System;

using System.IO;

using System.Xml;

class CMain

{

    static void Main(string[] files)

    {

        if (files.Length == 0)

            Console.WriteLine("Syntax:\n\txmlpp <filename> [<outfilename>]");

        XmlDocument doc = new XmlDocument();

        XmlTextReader rd = new XmlTextReader(files[0]);

        rd.WhitespaceHandling = WhitespaceHandling.None;

        doc.Load(rd);

        rd.Close();

        XmlTextWriter wr = new XmlTextWriter(files.Length == 1 ? files[0] : files[1], null);

        wr.Formatting = Formatting.Indented;

        doc.Save(wr);

        wr.Close();

    }

}

I wrote this down because I was doing some XML manipulation with the REXML library for Ruby yesterday and REXML seemed to dump relatively ugly XMLs no matter what formatting options I gave it.

Usage Examples:

            xmlpp file.xml

            xmlpp file.xml outfile.xml
