C#解析html库

网上查找有如下几个库

• SGMLReader (好久不更新了)
• html-agility-pack(活跃)
• AngleSharp(活跃)
• CsQuery(好久不更新)

选择AngleSharp

原因:能向写js一样获取元素
安装AngleSharp 1.2.0-beta.431

using AngleSharp.Html.Parser;

namespace HtmlParse01;

class Program
{
    static void Main(string[] args)
    {
        var htmlPart =
            @"<td>
    <div class='cell'>
        <div>编码</div>
    </div>
</td>
<td>
    <div class='cell'>
        <div>
            <div>1234567</div>
        </div>
    </div>
</td>";
        var parser = new HtmlParser();
        var htmlDocument = parser.ParseDocument(htmlPart);
        var cellDivs = htmlDocument.QuerySelectorAll(".cell");
        Console.WriteLine(cellDivs.Length);
        foreach (var cellDiv in cellDivs)
        {
            Console.WriteLine(cellDiv.TextContent.Trim());
        }
    }
}

结果如下

也可以向原生js一样操作dom，参考下面的文章
