求一个正则 抓起指—IV下的H5标签里的内容
样式如下：

HTML code

        <div class="dailyEcont" id="dailyEcont">                        <img class="fl dailyEimg" alt="" src="attachment/2012-05-23.jpg">            <div class="fl dailyEtext">                <h5 class="e">this test.                                <a class="laba" href="javascript:return false;" title="123">123</a>                                </h5>                <h5>测试 </h5>              ....              ....            </div>        </div>

要得到id为dailyEcont下的 this test. 和 测试

[解决办法]

C# code

            string str = @"<div class=""dailyEcont"" id=""dailyEcont"">                        <img class=""fl dailyEimg"" alt="""" src=""attachment/2012-05-23.jpg"">            <div class=""fl dailyEtext"">                <h5 class=""e"">this test.                                <a class=""laba"" href=""javascript:return false;"" title=""123"">123</a>                                </h5>                <h5>测试 </h5>              ....              ....            </div>        </div>";            Regex reg = new Regex(@"(?is)<div[^>]*?id=""dailyEcont""[^>]*?>(?:.*?<h5[^>]*?>([^<>]+).*?</h5>)*.*?</div>");            foreach (Capture c in reg.Match(str).Groups[1].Captures)                Console.WriteLine(c.Value);/*this test.测试*/
