Tag


The Tag object represents different tags of HTML and XML documents. The creation of Tag objects is done when parsing the documents. The different HTML/XML tags identified during parsing are represented as corresponding Tag objects and these objects will have attributes and contents of the HTML/XML tag. The Tag objects can be used for searching and navigation within the HTML/XML document.

Accessing the Tag object from BeautifulSoup

BeautifulSoup allows us to access any Tag object. For example, we can access the first occurrence of the <a> tag in the next example by simply calling the name of the tag <a>.

html_atag = """<html><body><p>Test html a tag example</p>

<a href="http;//www.packtpub.com/books'>Books</a>
</body>
</html>"""
soup  = BeautifulSoup(html_atag,'lxml')
atag = soup.a
print(atag)

The previous script will print the first <a> tag in the document. We can see...
