正则表达式来替换多个html属性 [英] Regular expression to replace several html attributes

问题描述

我有这个HTML：

<table style="width: 128px;" border="0" cellspacing="0" cellpadding="0">
<colgroup span="1"><col span="2" width="64"></col></colgroup>
<tbody>
<tr height="20">
<td width="64" height="20">&nbsp;</td>
<td class="xl65" dir="rtl" width="64"><strong></strong></td>
</tr>
<tr height="20">
<td class="xl67" dir="rtl" width="64" height="20">&nbsp;</td>
<td class="xl66" dir="ltr" width="64">T3500&nbsp;</td>
</tr>
<tr height="20">
<td class="xl68" width="64" height="20">&nbsp;</td>
<td>&nbsp;</td>
</tr>
<tr height="20">
<td height="20">&nbsp;</td>
<td class="xl65" dir="rtl" width="64"><strong></strong></td>
</tr>
<tr height="48">
<td class="xl67" dir="rtl" width="64" height="48">&nbsp;</td>
<td class="xl66" dir="ltr" width="64">Intel&reg; X58 Chipset&nbsp;</td>
</tr>
<tr height="33">
<td class="xl70" dir="rtl" width="64" height="33">&nbsp;</td>
<td class="xl69" dir="ltr" width="64">10/100/1000&nbsp;</td>
</tr>
<tr height="20">
<td class="xl68" width="64" height="20">&nbsp;</td>
<td>&nbsp;</td>
</tr>
<tr height="20">
<td height="20">&nbsp;</td>
<td class="xl65" dir="rtl" width="64"><strong></strong></td>
</tr>
<tr height="96">
<td class="xl67" dir="rtl" width="64" height="96">&nbsp;</td>
<td class="xl66" dir="ltr" width="64">One Intel Xeon W3503(2.4GHz,4.8GT/s,4MB,DC)&nbsp;</td>
</tr>
<tr height="20">
<td class="xl68" width="64" height="20">&nbsp;</td>
<td>&nbsp;</td>
</tr>
</tbody>
</table>

我想将所有样式，目录，高度，宽度和类替换为空白

i want to replace all style, dir, height, width and class with nothing so it will be removed

这是我为其中的一些人尝试的，它在在线测试程序中工作，但在记事本++中无效

this is what i have tried for some of them and it worked in an online tester but didn't work in notepad++

( class=\"([^\"]*)\"){0,} (width=\"([^\"]*)\"){0,} (height=\"([^\"]*)\"){0,}

推荐答案

试试

Try

\s*(?:style|dir|height|width|class)\s*=\s*"[^"]*"\s*

当然，这将删除文本，比如 style =hello，无论它们出现在哪里，也都在标签之外。

Of course this will remove texts like style="hello" wherever they may occur, also outside of tags.

可能Notepad ++不支持 \ s 简写。尝试使用

It may be that Notepad++ doesn't support the \s shorthand. Try using

[ ]*(?:style|dir|height|width|class) *= *"[^"]*" *

改为看看是否有效。 [] 在开始时可以被替换为一个空格。

instead and see if that works. The [ ] at the start can be replaced by a single space.
