python - Beautiful Soup and extracting a div and its contents by ID

asked Oct 17, 2021 in Technique[技术] by 深蓝 (71.8m points)

python - Beautiful Soup and extracting a div and its contents by ID

soup.find("tagName", { "id" : "articlebody" })

Why does this NOT return the <div id="articlebody"> ... </div> tags and stuff in between? It returns nothing. And I know for a fact it exists because I'm staring right at it from

soup.prettify()

soup.find("div", { "id" : "articlebody" }) also does not work.

(EDIT: I found that BeautifulSoup wasn't correctly parsing my page, which probably meant the page I was trying to parse isn't properly formatted in SGML or whatever)

You should post your example document, because the code works fine:

>>> import BeautifulSoup
>>> soup = BeautifulSoup.BeautifulSoup('<html><body><div id="articlebody"> ... </div></body></html')
>>> soup.find("div", {"id": "articlebody"})
<div id="articlebody"> ... </div>

Finding <div>s inside <div>s works as well:

>>> soup = BeautifulSoup.BeautifulSoup('<html><body><div><div id="articlebody"> ... </div></div></body></html')
>>> soup.find("div", {"id": "articlebody"})
<div id="articlebody"> ... </div>
