bs4 select 用style

如果要使用BeautifulSoup模块中的select方法来查找带有特定样式的元素，可以使用CSS选择器语法中的属性选择器。例如，要查找所有class属性为"myclass"的元素，可以使用以下代码：

from bs4 import BeautifulSoup

html = """
<div class="myclass">This is a div element with class="myclass".</div>
<div class="otherclass">This is a div element with class="otherclass".</div>
<div class="myclass">This is another div element with class="myclass".</div>
"""

soup = BeautifulSoup(html, 'html.parser')

# 通过class属性查找元素
elements = soup.select('div[class="myclass"]')
for element in elements:
    print(element.text)

输出结果为：

This is a div element with class="myclass".
This is another div element with class="myclass".

如果要查找带有特定style属性的元素，可以使用类似的方法。例如，要查找所有style属性为"color:red;"的元素，可以使用以下代码：

from bs4 import BeautifulSoup

html = """
<div style="color:red;">This is a div element with style="color:red;".</div>
<div style="background-color:blue;">This is a div element with style="background-color:blue;".</div>
<div style="color:red;">This is another div element with style="color:red;".</div>
"""

soup = BeautifulSoup(html, 'html.parser')

# 通过style属性查找元素
elements = soup.select('div[style="color:red;"]')
for element in elements:
    print(element.text)

输出结果为：

This is a div element with style="color:red;".
This is another div element with style="color:red;".
