Testing and Parsing an ASP.NET YSOD (Yellow Screen Of Death) from an XMLHttpRequest.responseText

After a minor bout of forgetfulness regarding legal regexp flags in Javascript, I knocked this one out that parses the comment block at the end of an YSOD.

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] };
}

will find and parse the comment block shown. I am guessing that is why they put it there....

<html>
<!-- omitted -->
    <body bgcolor="white">
		<!-- omitted -->
    </body>
</html>
<!-- 
[ArgumentException]: Unknown web method ValidateUser.
