PHP正则表达式从HTML表格中提取数据

问题描述

我现在得到的代码是：

 < table> 
< tr> 
< td> quote1< / td> 
< td>是否尝试关闭并再次开启？< / td> 
< / tr> 
< tr> 
< td> quote65< / td> 
< td>你不会偷一个警察的头盔< / td> 
< / tr> 
< / table> 
  

这个我想替换为：

quote1：你有试过它吗？

quote65：你不会偷一个警察的头盔

我已经写过的代码是这样的：

 ％< td>（（？s）。* ？）< / td>％
  

但现在我被卡住了。

解决方案

Tim的正则表达式可能有效，但您可能需要考虑使用PHP的DOM功能而不是正则表达式，因为它可能在处理次要标记的变化。

I'm trying to make a regex for taking some data out of a table.

the code i've got now is:

<table>
   <tr>
     <td>quote1</td>
     <td>have you trying it off and on again ?</td>
   </tr>
   <tr>
     <td>quote65</td>
     <td>You wouldn't steal a helmet of a policeman</td>
   </tr>
</table>

This I want to replace by:

quote1:have you trying it off and on again ?

quote65:You wouldn't steal a helmet of a policeman

the code that I already have written is this:

%<td>((?s).*?)</td>%

But now I'm stuck.

解决方案

Tim's regex probably works, but you may want to consider using the DOM functionality of PHP instead of regex, as it may be more reliable in dealing with minor changes in the markup.
