You can make the code from earlier version of Beautiful Soup compatible with the lates version by making following change in the import statement −
Example
from BeautifulSoup import BeautifulSoup #becomes this: from bs4 import BeautifulSoup
If you get the ImportError “No module named BeautifulSoup”, it means you”re trying to run Beautiful Soup 3 code, but you only have Beautiful Soup 4 installed. Similarly, If you get the ImportError “No module named bs4″, because you”re trying to run Beautiful Soup 4 code, but you only have Beautiful Soup 3 installed.
Beautiful Soup 3 used Python”s SGMLParser, a module that has been removed in Python 3.0. Beautiful Soup 4 uses html.parser by default, but you can also use lxml or html5lib.
Although BS4 is mostly backwards-compatible with BS3, most of its methods have been deprecated and given new names for PEP 8 compliance.
Here are a few examples −
replaceWith -> replace_with findAll -> find_all findNext -> find_next findParent -> find_parent findParents -> find_parents findPrevious -> find_previous getText -> get_text nextSibling -> next_sibling previousSibling -> previous_sibling
