获取页面[美汤]中所有标签的所有属性

Question

我想通过数组中的美丽汤获取html页面中每个标签的所有属性

例如我有一个 html 页面我想要一个字符串数组中的所有标签属性

<div att0="content1">
<a href="link1">link data</a>
</div>

结果将是：[content1, link1]

Answer 1

查找所有元素并从.attrsattribute获取属性：

attrs = []
for elm in soup():  # soup() is equivalent to soup.find_all()
    attrs += list(elm.attrs.values())

print(attrs)

演示：

>>> from bs4 import BeautifulSoup
>>> 
>>> data = """
... <div att0="content1">
... <a href="link1">link data</a>
... </div>
... """
>>> 
>>> soup = BeautifulSoup(data, 'lxml')
>>> 
>>> attrs = []
>>> for elm in soup():
...     attrs += list(elm.attrs.values())
... 
>>> print(attrs)
['content1', 'link1']
