分享正则表达式的问题
有一个字符串如下：
<html>
<head/>
<body>
<table width="520" cellspacing="1" cellpadding="5" border="0" bgcolor="#cccccc" align="center" bordercolordark="#ffffff">
<tbody>
<tr bgcolor="#e9f8d7">
<td align="center" colspan="4">身份证号码查询解读、验证和升级结果</td>
</tr>
<tr bgcolor="#ffffff">
<td colspan="4">
<script type="text/javascript">
</script>
<script src="http://images.sohu.com/cs/jsfile/js/cpc.js" type="text/javascript" language="JavaScript">
</script>
<iframe width="468" scrolling="no" height="42" frameborder="0" src="http://sogou.com/cpc_ads?pid=123cha&fmt=h_468_60&iw=468&ih=42&charset=gb2312&c_bo=FFFFFF&c_bg=FFFFFF&c_li=0055E5&c_te=000000&c_bt=000000&c_hl=FF0900&sv=0&sl=1&hl=0&tnt=0&sohuurl=http://localhost/index_test.php" allowtransparency="true" marginheight="0" marginwidth="0">
</iframe>
</td>
</tr>
<tr>
<td width="120" bgcolor="#f6f6f6" align="center">出生日期</td>
<td width="240" bgcolor="#ffffff" align="center">1982 年 02 月 13 日</td>
<td width="80" bgcolor="#f6f6f6" align="center">性别</td>
<td width="80" bgcolor="#ffffff" align="center">男</td>
</tr>
<tr>
</tr>
<tr>

<tr>

<tr height="28">
