从内嵌样式中删除高度和宽度 [英] Remove height and width from inline styles

问题描述

我使用BeautifulSoup从我的元素中删除内联高度和宽度。解决它的图像很简单：

  def remove_dimension_tags（tag）：
 for [width，高度]：
 del标签[属性] 
返回标签
  

'不知道如何处理这样的事情：

 < div id =attachment_9565class =wp- caption aligncenterstyle =width：2010px; background-color：red> 
  

当我想要保留背景色（例如）或任何其他样式属性高度或宽度。

我能想到的唯一方法就是使用正则表达式，但是上次我提出这样的想法时，StackOverflow的精神从我的计算机中出来，出生。

解决方案

完整的步骤是：

  from bs4 import BeautifulSoup 
 import re 
 
 string =
< div id =attachment_9565class =wp-caption 
< p> 
< p / gt; 
< p>> 
< p> < / p> 
< / div> 

 
＃寻找宽度或高度，然后不是a; 
 rx = re.compile（r'（？：width | height）：[^;] + ;?''）
 
 soup = BeautifulSoup（string，html5lib）
 
 for soup.findAll（'div'）：
 div ['style'] = rx.sub（，string）
  

正如其他人所说的，在实际值上使用正则表达式不是问题。

I'm using BeautifulSoup to remove inline heights and widths from my elements. Solving it for images was simple:

def remove_dimension_tags(tag):
    for attribute in ["width", "height"]:
        del tag[attribute]
    return tag

But I'm not sure how to go about processing something like this:

<div id="attachment_9565" class="wp-caption aligncenter" style="width: 2010px;background-color:red">

when I would want to leave the background-color (for example) or any other style attributes other than height or width.

The only way I can think of doing it is with a regex but last time I suggested something like that the spirit of StackOverflow came out of my computer and murdered my first-born.

解决方案

A full walk-through would be:

from bs4 import BeautifulSoup
import re

string = """
    <div id="attachment_9565" class="wp-caption aligncenter" style="width: 2010px;background-color:red">
        <p>Some line here</p>
        <hr/>
        <p>Some other beautiful text over here</p>
    </div>
    """

# look for width or height, followed by not a ;
rx = re.compile(r'(?:width|height):[^;]+;?')

soup = BeautifulSoup(string, "html5lib")

for div in soup.findAll('div'):
    div['style'] = rx.sub("", string)

As stated by others, using regular expressions on the actual value is not a problem.
