就想把引号里面的内容提取出来，怎么这么难啊..........
Match mc = Regex.Match(strXML, "\ "(? <content> [\s\S]*?)\ " ",RegexOptions.IgnoreCase);

大概想这样，就是出错~~~

[解决办法]
Match mc = Regex.Match(strXML, "\ "(? <content> [\\s\\S]*?)\ " ",RegexOptions.IgnoreCase);
或者
Match mc = Regex.Match(strXML,@ " " "(? <content> [\s\S]*?) " " ",RegexOptions.IgnoreCase);
