解决方法
HAP不会给你你想要的结果.
尝试使用HtmlTidy的.net包装器,例如找到的一个here
using System; using System.IO; using System.Net; using Mark.Tidy; namespace CleanupHtml { /// <summary> /// http://markbeaton.com/SoftwareInfo.aspx?ID=81a0ecd0-c41c-48da-8a39-f10c8aa3f931 /// </summary> internal class Program { private static void Main(string[] args) { string html = new WebClient().DownloadString( "https://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); } } } }
结果:
