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>
</tr>
<tr>
</tr>
<tr>
</tr>
<tr height="28">
</tr>
</tbody>
</table>
</body>
</html>
我想把 <tr bgcolor="#ffffff"> 数据挖掘研究院
<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> 这段代码给去掉，正则表达式怎么写？？
- PHP code
- $ptn="/<tr +bgcolor="#ffffff">.*?</tr>/is"; $str=preg_replace($ptn,"",$str);数据挖掘研究院
- PHP code
- $ptn="/<tr +bgcolor="#ffffff">[sS]*</tr>/is"; $str=preg_replace($ptn,"",$str);
试试呢？
好像"."不匹配回车什么的薄荷脑，你的方法不行。不过还是谢谢你
- PHP code
- $search = "/<tr(.*?)<iframe (.*?)</tr>/is"; preg_replace($search,"------------",$str);数据挖掘研究院
- PHP code
- $search = "/<tr(.*?)<iframe (.*?)</tr>/is"; $y = preg_replace($search,"",$str);数据挖掘研究院
为什么我试用了可以??
- PHP code
- <?php $str = "<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> </tr> <tr> </tr> <tr> </tr> <tr height="28"> </tr> </tbody> </table> </body> </html> "; $search = "/<tr(.*?)<iframe (.*?)</tr>/is"; $result = preg_replace($search,"",$str); echo htmlspecialchars($result); ?>
$handle = fopen("http://www.123cha.com/idcard/352601198202134013/", "rb");
$contents = stream_get_contents($handle);
$contents = eregi_replace(".* <table id="tb"", " <table", $contents);
$contents = eregi_replace(" </table> .*", "", $contents);
//$contents = eregi_replace(" <tr +bgcolor="#ffffff"> (.*?) </iframe> </td> </tr> ", "", $contents);
//$ptn = "/ <tr +bgcolor="#ffffff"> (.*?) </iframe> </td> </tr> /is";
//$contents=preg_replace($ptn,"",$contents);
echo $contents;
?>
可能是我没说清楚，不好意思，我会适当加分
代码如上，我要去掉那个广告
