如何用漂亮的汤/ python重建xml密钥？

Question

So, using beautiful soup, I am trying to parse through a large xml file and strip out the first string (before .) from each key name.

Just as an example:

currently print key gives me:

<key name="app-suite.multi.port" value="15022"></key>

and print key["name"].split(".")[1:] gives me:

['multicast', 'port']

Stripping out app-suite out of the keyname is the desired result, however I'm not sure how to rebuild this key. Currently the above line just returns a list with the correct elements.

How do I actually turn this into a key or modify the original key by removing 'app-suite'?

Assuming you actually want to keep the . in multi.port , it is better to use split(., 1) so that you only split on the first instance of . . You can use the following:

from bs4 import BeautifulSoup

content = '<key name="app-suite.multi.port" value="15022"></key>'
soup = BeautifulSoup(content)
key = soup.find('key')
key['name'] = key["name"].split(".", 1)[1]
print(key)

Output

<key name="multi.port" value="15022"></key>
