In the below example, we’ll get the value of thehref attribute.
Beautifulsoup: Find all by multiple attributes
Let say we want to find all elements that have «setting-up-django-sitemaps» in the href attribute and «link» in the id.
Beautifulsoup: Check if an attribute exists
Return True if the attribute exists, otherwise False.
How to Create Django Sitemaps
''' soup = BeautifulSoup(html_source, 'html.parser') # Find element el = soup.find("a") #check href attribute print(el.has_attr('href')) #check name attribute print(el.has_attr('name'))
Beautifulsoup: Find attribute contains a number
in this last part of this tutorial, we’ll find elements that contain a number in the id attribute value. To do this, we need to use Regex with Beautifulsoup.
How to get attributes of elements in BeautifulSoup
Anyone out there who has gotten into website scraping and web scraping will know the importance of the BeautifulSoup (bs4) library. Parsing data of HTML pages is a common issue while working with web scraping, BeautifulSoup makes this process much easier by adding ‘soup’ to the line of your code. It will identify the tags of the given page, allowing you to scrap that data very easily. If you’re having trouble finding reliable and clean data on the internet, be sure to use bs4 library.
In this article, we will learn how to get the attributes of an element in a BeautifulSoup tree.
Extract attribute from an element
BeautifulSoup allows you to extract a single attribute from an element given its name just like how you would access a Python dictionary.
element[]For example, the following code snippet prints out the first author link from Quotes to Scrape page.
Sometimes, the attribute may or may not be present on all elements. In that case, trying to extract it will raise KeyError .
In [ ----> -> In this situation, you should use the get() method to safely get the attribute out of the element. The method returns the attribute value if it’s found, and None value otherwise.
In order to get all attributes of an element, you have to print out the attrs property of the element like what’s demonstrated below.
In [ Turning the attributes into lists is easy, too, just use keys() and values() to do that. If you absolutely need a Python list, you can also cast the whole result into a list.
In [ If you want to filter HTML/XML tags that has the same attribute, you can pass a dict to attrs dictionary of find() or find_all() .
A common scenario is getting attributes of tags that matches a certain condition. This all boils down to selecting/fitlering the right elements.
You can use the find() and find_all() method with class_ , id , attrs arguments to do that. But did you know that you can even use regex?
The example below use regex to find all elements that contain numbers on id attributes.
soup.find_all(id=re.compile( find() and find_all() method also supports searching by a function, which we can use to our advantage.
