C# 在C中解析具有Html灵活性的表、单元格#
我需要解析Html代码。更具体地说，解析所有表中每行的每个单元格。每行表示一个对象，每个单元格表示不同的属性。我想解析这些，以便能够编写一个包含所有数据的XML文件（没有无用的HTML代码）。我已经成功地解析了HTML文件中的每一列，但现在我不知道将其写入XML文件的选项是什么。我很困惑 HTML:C# 在C中解析具有Html灵活性的表、单元格#,c#,html-agility-pack,xml-parsing,html-parsing,C#,Html Agility Pack,Xml Parsing,Html Parsing,我需要解析Html代码。更具体地说，解析所有表中每行的每个单元格。每行表示一个对象，每个单元格表示不同的属性。我想解析这些，以便能够编写一个包含所有数据的XML文件（没有无用的HTML代码）。我已经成功地解析了HTML文件中的每一列，但现在我不知道将其写入XML文件的选项是什么。我很困惑 HTML: 1. 矿井 C 39 32 33 65 20 29 10 1. 3. 0 154 20.8 21:54 22.6 55.7 C#： 使用HtmlAgilityPack； 命名空间统计信息 { 类
