我可以使用Html Agility Pack使输出看起来很好地缩进，不必要的空白区域被剥离了吗？
答案 0 :(得分：8)
HAP不会为您提供您所追求的结果。
尝试为HtmlTidy使用.net包装器，例如找到的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(
"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);
}
}
}
}
结果：

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

<p>
This article covers how to use it but you had to sign up (free) to view it:

答案 1 :(得分：1)
最近已回答了这个问题的一个变体
基本上这样做的结果是，当你可以使用HtmlAgilityPack通过使用修复嵌套标签来清理它时。
最好的解决方案是使用一个名为Tidy的东西，这是一个最初由w3c的一些开发人员创建然后开源的应用程序。它也是为w3c验证器提供动力的引擎。
本文介绍了如何使用它，但您必须注册（免费）才能查看它：
它似乎是一篇合法的文章，但它很有趣，因为在过去的六年中似乎没有其他人覆盖过这个话题......
答案 2 :(得分：1)
在此处查看类似问题：HtmlAgilityPack: how to create indented HTML?和我的回答：
不，这是“按设计”选择。 XML之间存在很大差异 （或XHTML，它是XML，而不是HTML） 在哪里 - 大部分时间 - 空格没有特定的意义， 和HTML。
这不是一个如此微小的改进，因为 改变空格可以改变 一些浏览器呈现给定HTML的方式 块，特别是格式错误的HTML（那个 总的来说，处理得很好 图书馆）。和Html敏捷包 旨在最小化的方式 呈现HTML，而不是像 标记是写的。
我不是说这不可行或 简直不可能。显然你可以 转换为XML和voilà（和你 可以写一个扩展方法 使这更容易）但渲染 输出可能不同，在 一般情况。
