Python BeautifulSoup equivalent to lxml make_links_absolute

Question

So lxml has a very hand feature: make_links_absolute:

doc = lxml.html.fromstring(some_html_page)
doc.make_links_absolute(url_for_some_html_page)

and all the links in doc are absolute now. Is there an easy equivalent in BeautifulSoup or do I simply need to pass it through urlparse and normalize it:

soup = BeautifulSoup(some_html_page)
for tag in soup.findAll('a', href=True):
    url_data = urlparse(tag['href'])
    if url_data[0] == "":
        full_url = url_for_some_html_page + test_url

Answer 1

In my answer to What is a simple way to extract the list of URLs on a webpage using python? I covered that incidentally as part of the extraction step; you could easily write a method to do it on the soup and not just extract it.

from urllib.parse import urljoin

def make_links_absolute(soup, url):
    for tag in soup.findAll('a', href=True):
        tag['href'] = urljoin(url, tag['href'])

(Python 2: from urlparse import urljoin.)
