How to Efficiently Extract HREF Attributes from HTML Using BeautifulSoup?

Extracting HREF from BeautifulSoup

When working with HTML documents using BeautifulSoup, extracting specific attributes like href can be essential. This article provides solutions to retrieve href values efficiently, even in scenarios where multiple tags are present.

Using find_all for HREF Retrieval

To target only a tags with href attributes, employ the find_all method as follows:

<code class="python"># Python2
from BeautifulSoup import BeautifulSoup

html = '''<a href="some_url">next</a>
<span class="class"><a href="another_url">later</a></span>'''

soup = BeautifulSoup(html)

for a in soup.find_all('a', href=True):
    print "Found the URL:", a['href']</code>

This approach allows you to iterate through all the found a tags and print their href values. Note that for BeautifulSoup versions before 4, the method name was findAll.

If you wish to obtain all tags possessing href attributes, you can simply omit the name parameter:

<code class="python">href_tags = soup.find_all(href=True)</code>
