关于属性正则表达式的匹配
我想匹配所有的属性ID=\"Content1\" ContentPlaceHolderID=\"head\" runat=\"Server\"

 string html= "<asp:Content ID=\"Content1\" ContentPlaceHolderID=\"head\" runat=\"Server\">";
string pattern = "\\s*(?<key>[^=]+)=\"(?<value>[^\"]+?)\"";
        foreach (Match item in Regex.Matches(html, pattern))
        {
            Response.Write("key=" + item.Groups["key"].Value+"<br/>");
            Response.Write("value=" + item.Groups["value"].Value + "<br/>");
            Response.Write("================================<br/>");
        }
        Response.End();

我写的匹配结果为:

key=value=Content1
================================
key=ContentPlaceHolderID
value=head
================================
key=runat
value=Server
================================

ID匹配不到，求大神解决方案?
[解决办法]

 string pattern = "\\s+(?<key>[^=]+)=\"(?<value>[^\"]+?)\"";
