我在http://regextester.com建立了这个正则表达式来解析 YSOD，但 VS 抱怨语法错误。我确定我在某个地方错过了逃生机会，但我却一无所获。

这是原始形式。任何帮助表示赞赏。

var rxYSOD = /<!--\s*\[(.*?)]:(\s*.*\s(.*\n)*?)\s*(at(.*\n)*)-->/gs;

更新： 科比指出了显而易见的事情，让我再次动起来。对于那些感兴趣的人来说，这是一个有效的 JavaScript 来测试和解析 ASP.net 黄屏死机 (YSOD) 的 XMLHttpRequest.responseText。

var rxYSOD = /<!--\s*\[(.*?)]:(\s*.*\s(.*[\n\r]*)*?)\s*(at(.*[\n\r]*)*)-->/;
if (rxYSOD.test(text)) {
    // looks like one..
    var ysod = rxYSOD.exec(text);
    errObj = { Message: ysod[2], StackTrace: ysod[4], ExceptionType: ysod[1] };
}

@Kobi - 这是我想要解析 html 的结果和原因，即使我得到 500：

火狐 说：

Error: invalid regular expression flag s
Source Code:
var rxYSOD = /<!--\s*\[(.*?)]:(\s*.*\s(.*\n)*?)\s*(at(.*\n)*)-->/gs;

删除后s似乎没问题（当然，它没有经过测试，只是正确解析）。

该标志s在 Javascript 中无效。要替换，请使用该replace方法。
