我想匹配  中的所有内容，但找不到正则表达式... 第一场比赛应该看起来像这样:

<!--(?<NodeContent>[^//\-\-\>]*)//-->

这是我试过的，但它匹配每个字符!这意味着如果/、- 和 > 位于  内，它将失败。有人知道如何解决这个问题吗？

这是整个文档结构的样子:http://pastebin.com/cyESrLTB - 我的目标是将其转换为 XML。

请您参考如下方法:

尝试:

<!--(?<NodeContent>.*?)//-->

?将匹配标记为“惰性”，因此它将尝试匹配尽可能少的字符。打破这一点:

<!-- - 匹配<!--
(?<NodeContent>.*?) - 匹配.*?懒惰地，给它一个组名 NodeContent .
//--> - 匹配//-->

c#之正则表达式:匹配除 X 以外的所有内容，然后匹配 X
