我尝试在C＃中使用以下正则表达式。

var reg1 = Regex.Replace(node.InnerText, @"\t|\n|,|<!--(.*?)-->|(&nbsp.), " ");

var reg2 = Regex.Replace(node.InnerHtml, @"/\t+/|/\n+/|", "*");

问题是多个\ t只是被空格替换，我想用一个空的空格替换大量的\ t，最终目标是将整个东西导出到csv，同时具有一定的可读性。

Answer 1

你可以说：

result = Regex.Replace(node.InnerText, @"\t{2,}", @"\t");

这会将多个标签替换为一个标签。

Answer 2

您可以尝试：

Regex.Replace(node.InnerText, @"(\\t|\\n|&nbsp;)+", "");

参见 Live demo 。

替换多个选项卡和c＃regex中的单个选项卡
