今回はBeautifulSoupで特定のHTMLタグ要素を削除・置換するメソッドについてメモしておきます。

BeautifulSoupで特定のHTMLタグ要素を削除・置換する

PythonのBeautifulSoupでは、.extract(), .replace_with() 関数を使うことで特定のHTMLタグ要素を削除・置換が行えます。

from bs4 import BeautifulSoup

txt = """<p>I have a dog.  His name is <span class="secret">Ken</span>.</p>"""

soup = BeautifulSoup(txt)

# This keeps "unwanted" information
soup.get_text()
#: u'I have a dog.  His name is Ken.'


# remove an element by tag matching 
soup.find("span", {"class":"secret"}).extract()
soup.get_text()
#: u'I have a dog.  His name is .'


# or you can replace that with something
soup = BeautifulSoup(txt)
soup.find("span", {"class":"secret"}).replace_with("confidential")
soup.get_text()
#: u'I have a dog.  His name is confidential.'
