Html Agility Pack: make code look neat

Question

Can I use Html Agility Pack to make the output look nicely indented, unnecessary white space stripped?

Answer 1

HAP is not going to give you the results you are after.

Try using a .net wrapper for HtmlTidy such as the one found here

using System;
using System.IO;
using System.Net;
using Mark.Tidy;

namespace CleanupHtml
{
    /// 

    /// http://markbeaton.com/SoftwareInfo.aspx?ID=81a0ecd0-c41c-48da-8a39-f10c8aa3f931
    /// 
    internal class Program
    {
        private static void Main(string[] args)
        {
            string html =
                new WebClient().DownloadString(
                    "http://stackoverflow.com/questions/2593147/html-agility-pack-make-code-look-neat/2610903#2610903");

            using (Document doc = new Document(html))
            {
                doc.ShowWarnings = false;
                doc.Quiet = true;
                doc.OutputXhtml = true;
                doc.OutputXml = true;
                doc.IndentBlockElements = AutoBool.Yes;
                doc.IndentAttributes = false;
                doc.IndentCdata = true;
                doc.AddVerticalSpace = false;
                doc.WrapAt = 120;

                doc.CleanAndRepair();

                string output = doc.Save();
                Console.WriteLine(output);
                File.WriteAllText("output.htm", output);
            }
        }
    }
}

                        A variation of this question has been answered recently

                        Basically the outcome of this was that while you can use HtmlAgilityPack to
                        clean it up a bit by using the fix nested tags.
                      
                      

                        The best solution is to use something called Tidy which is an application that was originally
                        created by some developers at w3c and then made open source. Its the engine that powers the w3c
                        validator as well.
