c# - HTML敏捷包: how to create indented HTML?

Question

所以，我正在使用 HtmlAgilityPack 生成 html，它运行良好，但 html 文本没有缩进。然而，我可以获得缩进的 XML，但我需要 HTML。有办法吗？

HtmlDocument doc = new HtmlDocument();

// gen html
HtmlNode table = doc.CreateElement("table");
table.Attributes.Add("class", "tableClass");
HtmlNode tr = doc.CreateElement("tr");
table.ChildNodes.Append(tr);
HtmlNode td = doc.CreateElement("td");
td.InnerHtml = "—";
tr.ChildNodes.Append(td);

// write text, no indent :(
using(StreamWriter sw = new StreamWriter("table.html"))
{
        table.WriteTo(sw);
}

// write xml, nicely indented but it's XML!
XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;
settings.Indent = true;
settings.ConformanceLevel = ConformanceLevel.Fragment;
using (XmlWriter xw = XmlTextWriter.Create("table.xml", settings))
{
        table.WriteTo(xw);
}

快速、可靠、纯 C#、.NET Core 兼容的 AngleSharp

你可以用 AngleSharp 解析它它提供了一种自动缩进的方法:

var parser = new HtmlParser();
var document = parser.ParseDocument(text);
using (var writer = new StringWriter())
{
    document.ToHtml(writer, new PrettyMarkupFormatter
                            {
                                Indentation = "\t",
                                NewLine = "\n"
                            });
    var indentedText = writer.ToString();
}
