Select 带有 beautifulsoup 点的标签

Question

如何使用 beautifulsoup select 并用其他文本修改标签 <Tagwith.dot>？如果 beautifulsoup 不可能，那么 xml 文档编辑和创建的下一个最佳库是 lxml?

from bs4 import BeautifulSoup as bs

stra = """
<body>
<Tagwith.dot>Text inside tag with dot</Tagwith.dot>
</body>"""
soup = bs(stra)

想要XML：

<body>
<Tagwith.dot>Edited text</Tagwith.dot>
</body>

Answer 1

您可以使用xml.etree.elementtree实现您想要的效果如下

import xml.etree.ElementTree as ET

stra = """
<body>
<Tagwith.dot>Text inside tag with dot</Tagwith.dot>
</body>"""

#Read xml string and convert to xml object
xml_obj = ET.fromstring(stra)

#Iterate through elements
for elem in xml_obj:
    #If tag is found, modify the text
    if elem.tag == 'Tagwith.dot':
        elem.text = 'Edited text'

#Print updated xml object as a string
print(ET.tostring(xml_obj).decode())

输出将是

<body>
<Tagwith.dot>Edited text</Tagwith.dot>
</body>

Answer 2

BS4 假定并将所有标签转换为小写。下面的代码工作正常。提供小写的标签名称。

from bs4 import BeautifulSoup as bs

stra = """
<body>
<Tagwith.dot>Text inside tag with dot</Tagwith.dot>
</body>"""
soup = bs(stra, 'html.parser')

print(soup.find_all('tagwith.dot'))

输出：

[<tagwith.dot>Text inside tag with dot</tagwith.dot>]
