(* For example, I want to skip all links, skip charts, etc.)
Use the .extract () and .replace_with () functions in Python BeautifulSoup.
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.'
