Webscraper Package Python How To Build A
Content = urllib.request.urlopen('')In this section, we will look at the step by step guide on how to build a basic web scraper using python Beautiful Soup module. The URL of this web page is passed as the parameter to this request. We will make use of this request function send an HTML GET request to Wikipedia server to render us the webpage. Also, for our web scraper, we will use the Python packages BeautifulSoup (for selecting specific data) and Selenium (for rendering dynamically loaded content).Will import the urllib package’s request function into our Python program. In such a case, the python library request would not work and it would.Let us now fetch this web page using Python library urllib by issuing the following command: import urllib.requestTo check if you already have Python installed on your device, run the following command: python3 -v If you have Python installed, you should receive an output like this: Python 3.8.2.
However, as a web scraper we are mostly interested only in human readable content and not so much on meta content. This also includes certain HTML meta tags that are used as directives to web browser such as tags. It is this content that is stored in the Python program’s “ content” variable.The content variable will hold all the HTML content sent back by the Wikipedia server.

It is now time to extract individual data elements of the web page. Read_content = content.read()The above line of Python code will give us only those HTML elements which contain human readable contents.At this point in our program we have extracted all the relevant HTML elements that we would be interested in. We achieve this in the next line of the program by calling the read() function of urllib package.
We are now going to pass this variable along with the flag ‘html.parser’ to Beautifulsoup to extract html elements as shown below: from bs4 import BeautifulSoupSoup = BeautifulSoup(read_content,'html.parser')From this point on wards, our “soup” Python variable holds all the HTML elements of the webpage. Hope you remember that we had earlier stored our web content in the Python variable “ read_content“. Using this library, we will be able to extract out the exact HTML element we are interested in.We can install Python Beautifulsoup package into our local development system by issuing the command: pip install bs4Once Beautifulsoup Python package is installed, we can start using it to extract HTML elements from our web content. Beautifulsoup is a Python package that can understand HTML syntax and elements.
Webscraper Package Python How To Extract All
How To Extract All The H2 Elements Of A Web PageExtracting H2 elements of a web page can also be achieved in a similar way as how we did for the paragraphs earlier. In a similar way, we can extract other HTML elements too as shown in the next section. What if we try the next index? pAll.textWe again get a newline! Now what about the third index? pAll.text"A comet is an icy, small Solar System body that."And now we get the text of the first paragraph of the article! If we continue further with indexing, we can see that we continue to get access to every other HTML element of the article. So in order to access the first paragraph, we issue the command: pAll.textSo the first paragraph only contained a new line. Now pAll contains a list of all paragraphs, so each individual paragraphs can be accessed through indexing. How To Extract All The Paragraphs Of A Web PageFor example, if we want to extract the first paragraph of the wikipedia comet article, we can do so using the code: pAll = soup.find_all('p')Above code will extract all the paragraphs present in the article and assign it to the variable pAll.
We can extract any type of HTML elements using similar approach – be it images, links, tables etc. By making use of these functions, we can address individual elements of the web page.So far we have seen how we could extract paragraphs and h2 elements from our web page. Beautifulsoup will then provides us with many useful functions (find_all, text etc) to extract individual HTML elements of the web page. By making use of the two important libraries – urllib and Beautifulsoup.We first pull the web page content from the web server using urllib and then we use Beautifulsoup over the content. This is how we extract data from website using Python.
