c# - 正则表达式：匹配除 X 之外的所有内容，然后是 X

Question

我会尽量让你容易理解：

我想匹配 <!-- //--> 中的所有内容，找不到正则表达式...第一个匹配项应如下所示：

   <BASIC_INFO>
       KOREAN                      =   ¼®À¯
       ENGLISH                     =   OIL

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

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

编辑

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。

Answer 1

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。打破这个：

• <!--- 匹配<!--
• (?<NodeContent>.*?)- 懒惰匹配.*?，并给它一个组名NodeContent。
• //-->- 匹配//-->

你在这里不需要正则表达式，使用像HtmlAgilityPack这样的 html 解析器

var doc = new HtmlAgilityPack.HtmlDocument();
doc.Load(fname);
var comments = doc.DocumentNode.SelectNodes("//comment()")
                .Select(n => n.InnerText)
                .ToList();
