What is Web Scraping

Web scraping is the process of extracting data from websites automatically and converting it into a structured format for further analysis. It involves using software or scripts to access web pages, download their contents, and extract specific information from them. The data retrieved through web scraping can include text, images, URLs, tables, and more.

Why do we need to Web Scrape?

Think of a scenario where you want to find the perfect holiday destination for your upcoming trip. You’re eager to compare hotel prices, check out tourist attractions, and read reviews from fellow travellers. However, the thought of manually visiting each travel website, copying information, and organizing it into a meaningful format sounds daunting and time-consuming. This is where web scraping comes to the rescue.

Imagine having a virtual travel assistant that can swiftly visit various travel websites, scrape hotel prices, tour packages, and user reviews, and present it all in a neat and organized manner. Within minutes, you have a comprehensive overview of different destinations, their offerings, and the experiences of other travelers. With a little help of web scraping, all this could be possible.

Getting Started with Web Scraping

Before delving into web scraping techniques, it’s essential to first determine the type of website you intend to scrape, as there are two main categories: static and dynamic websites. Understanding this distinction will help you choose the appropriate approach and tools for your web scraping endeavor.

Types of Websites

There are two main types of websites:

1. Static:

Static websites are websites that do not change unless they are manually updated. They are typically made up of HTML, CSS, and JavaScript files that are stored on a web server. When a user visits a static website, their browser downloads the files and renders them as a web page.

Here are some examples of static websites:

Portfolio websites that showcase a person’s work
Company websites that provide information about a business
Blogs that are updated infrequently

2. Dynamic:

Dynamic websites are websites that can change depending on the user’s input or the current state of the website. They are typically made using server-side programming languages such as PHP, Python, or Java. When a user visits a dynamic website, their request is sent to the web server, which then executes the appropriate code to generate the web page.

Here are some examples of dynamic websites:

E-commerce websites that allow users to buy and sell products
Social media websites that allow users to interact with each other
News websites that update their content frequently

The best type of website for you will depend on your specific needs. If you need a website that is simple and easy to maintain, then a static website may be a good choice. However, if you need a website that is more interactive or dynamic, then a dynamic website may be a better choice.

Various Approaches to scrape data from websites.

Let’s explore the numerous approaches available to extract data from diverse websites, examining each method in detail.

Use of Web Scraping Libraries for Data Extraction

Web scraping libraries are tools that allow developers to extract data from websites programmatically. These libraries provide convenient methods and utilities to navigate web pages, retrieve data, and parse the content in a structured format. Some popular web scraping libraries include.

NOTE:

When it comes to automated scraping, legality is a significant concern. Some websites explicitly prohibit scraping in their terms of service. Others may allow scraping for personal use but not for commercial purposes. Before performing any scraping, it is essential to review the website’s terms of service and, if necessary, seek permission from the website owner to avoid potential legal issues.

The Use of APIs for Data Extraction

APIs (Application Programming Interfaces) plays a vital role in data extraction by providing a structured and standardized way for different software applications to communicate and exchange information. In the context of data extraction, APIs act as bridges between data sources, such as websites or web services

, and the applications that need to retrieve specific data from them.

When extracting data using APIs, developers can send requests to the API server, specifying the type of data they want and any parameters needed for the query. The API server then processes the request and returns the requested data in a structured format, such as JSON or XML. This data can include text, images, statistics, or any other relevant information available through the API.

Using APIs for data extraction offers several advantages. Firstly, APIs provide a consistent and predictable way to access data, ensuring that the information retrieved is always in a standardized format. Secondly, APIs often come with built-in security mechanisms, such as API keys or authentication tokens, which control access to data and prevent unauthorized usage. Thirdly, APIs can be more efficient than traditional web scraping methods, as they allow direct access to the specific data required without having to parse and navigate through entire web pages.

Furthermore, APIs are often maintained and updated by the service providers, ensuring that the data accessed through them is reliable, up-to-date, and compliant with the latest standards. Many websites and platforms offer APIs as part of their services, making it easier for developers to access and integrate data into their applications.

NOTE:

Using APIs for data extraction is generally more acceptable from a legal standpoint compared to web scraping. When you use an API, you are directly cooperating with the data provider and adhering to their terms of service. API providers set rules and restrictions on how their data can be accessed and used, and by using their API, you agree to abide by those rules.

However, it is essential to review the API provider’s terms of service and usage policies to ensure you are in compliance. Some APIs may have usage limits, require attribution, or charge fees for access beyond a certain threshold.

Web Scraping on Python

Let’s explore the fundamentals of web scraping using Python, examining the basic techniques for extracting data from websites. By delving into the basics, you’ll gain a better understanding of the different approaches to web scraping. Let’s get started!

.Let’s get started!

-Loading Necessary Packages

-Scraping for Static Website

-Scraping for Dynamic Website

-Advanced Scraping

1. Understanding Web Scraping

Web scraping involves accessing websites, downloading HTML content, and extracting relevant data. It’s essential to know the basics of HTML, CSS, and HTTP requests to get started.

2. Understanding HTML and CSS

HTML (Hypertext Markup Language) is used to structure the content of a webpage, while CSS (Cascading Style Sheets) is used to style and layout the HTML elements. Understanding these two is crucial for web scraping as it helps you locate and extract the data you need.

HTML (Hypertext Markup Language): HTML is the backbone of web pages and is used to structure the content of a website. It consists of various elements, each represented by tags, which define the structure and layout of the page. Web scrapers use HTML tags to identify and extract specific data from a webpage. For example, a data table on a website may be enclosed within “table” tags, and each row of the table may be represented by “tr” tags.

CSS (Cascading Style Sheets):

CSS is a style sheet language used to control the presentation and layout of web pages. It defines how HTML elements should be displayed on the screen, specifying attributes such as font size, colour, and positioning. While web scraping focuses on data extraction, understanding CSS selectors can be valuable for targeting specific elements within the HTML document efficiently.

3. Installing Required Libraries

Assuming you have chosen BeautifulSoup to web scrape. Firstly, you need to install it, use the following command on your terminal or command prompt.

pip install beautifulsoup4

This command will download and install the BeautifulSoup library on your system. BeautifulSoup is a popular Python library for web scraping, and it simplifies the process of parsing HTML and XML documents, making it easier to extract data from websites. Once installed, you can use the BeautifulSoup library in your Python scripts to navigate and extract information from web pages effortlessly.

Depending on the usage and the website, you can choose to install other necessary packages like

pip install requests
pip install selenium

Let’s explore different situations where you can effectively utilize these in web scraping. Understanding its usage in various scenarios will provide valuable insights into how these libraries can be applied to extract data from websites efficiently and adapt to different web scraping needs.

4. Loading Necessary Packages

We will introduce and explore several packages that we will use one by one for web scraping. Additionally, feel free to utilize any other packages of your choice, as Python offers a wide range of tools that can enhance and streamline the web scraping process.

import requests
from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.chrome.options import Options

Our focus will be on demonstrating the versatility of these packages and how they can be combined to extract valuable data from websites efficiently. So, let’s get ready to explore the world of web scraping with Python and unleash the power of various packages to make our scraping endeavours more effective and enjoyable.

5. Scraping for Static Website

Now that we have understood what are static websites, the simplest way to scrape them is using the ‘requests’ library. Since static websites present all the data directly in the HTML code when the page loads, this makes it easier to extract information using libraries like BeautifulSoup.

Let us consider an example to scrape a static website i.e.,

Input:

import requests
from bs4 import BeautifulSoup

url = 'https://en.wikipedia.org/wiki/Web_scraping'
response = requests.get(url)

print(response.status_code)
print(response.content)

Output:

200
b'<!DOCTYPE html>\n<html class="client-nojs vector-feature-language-in-header-enabled vector-feature-language-in-main-page-header-disabled vector-feature-sticky-header-disabled vector-feature-page-tools-pinned-disabled vector-feature-toc-pinned-enabled vector-feature-main-menu-pinned-disabled vector-feature-limited-width-enabled vector-feature-limited-width-content-enabled vector-feature-zebra-design-disabled" lang="en" dir="ltr">\n<head>\n<meta charset="UTF-8">\n<title>Web scraping - Wikipedia</title>\n<script>document.documentElement.className="client-js vector-feature-language-in-header-enabled vector-feature-language-in-main-page-header-disabled vector-feature-sticky-header-disabled vector-feature-page-tools-pinned-disabled vector-feature-toc-pinned-enabled vector-feature-main-menu-pinned-disabled vector-feature-limited-width-enabled vector-feature-limited-width-content-enabled vector-feature-zebra-design-disabled";(function(){var cookie=document.cookie.match(/(?:^|; )enwikimwclientprefs=([^;]+)/);if(cookie){var featureName=cookie[1];document.documentElement.className=document.documentElement.className.replace(featureName+\'-enabled\',featureName+\'-disabled\');}}());RLCONF={"wgBreakFrames":false,"wgSeparatorTransformTable":["",""],"wgDigitTransformTable":["",""],"wgDefaultDateFormat":"dmy","wgMonthNames"

In this code snippet, we are performing web scraping on the Wikipedia page about “Web scraping.” Let’s break down the steps:

url = ‘https://en.wikipedia.org/wiki/Web_scraping’: We define the URL of the webpage we want to scrape, which is the Wikipedia page on Web scraping.
response = requests.get(url): We use the requests library to make an HTTP GET request to the specified URL. This request is used to fetch the content of the webpage.
print(response.status_code): After making the request, we print the status code of the response. The status code is a three-digit number that indicates the result of the HTTP request. A status code of 200 means the request was successful, while a status code starting with 4 or 5 indicates an error (e.g., 404 for “Not Found” or 500 for “Internal Server Error”). This is an optional step, mainly used for error handling.
print(response.content): We print the content of the response, which contains the HTML content of the webpage. This content is a raw byte-string representation of the HTML page.

Input:

soup = BeautifulSoup(response.content, 'html.parser')
print(soup)

Output:

<!DOCTYPE html>

<html class="client-nojs vector-feature-language-in-header-enabled vector-feature-language-in-main-page-header-disabled vector-feature-sticky-header-disabled vector-feature-page-tools-pinned-disabled vector-feature-toc-pinned-enabled vector-feature-main-menu-pinned-disabled vector-feature-limited-width-enabled vector-feature-limited-width-content-enabled vector-feature-zebra-design-disabled" dir="ltr" lang="en">

Let us break down the following code snippet

soup = BeautifulSoup(response.content, ‘html.parser’): We create a BeautifulSoup object named soup by passing two arguments: response.content and ‘html.parser’. The first argument, response.content, contains the raw HTML content of the webpage obtained from the previous requests.get() call. The second argument, ‘html.parser’, is the name of the parser that BeautifulSoup should use to parse the HTML content. In this case, we are using the built-in HTML parser provided by BeautifulSoup, which is called html.parser.
print(soup): We are just displaying the content further

Let us assume we want to find the title of this page, we need to seach on the HTML page the class that holds the title element.

Input:

title_element = soup.find('span', class_='mw-page-title-main')
print(title_element)
print(title_element.text.strip())

Output:

<span class="mw-page-title-main">Web scraping</span>
Web scraping

7. title_element = soup.find(‘span’, class_=’mw-page-title-main’): We use the soup.find() method to search for an HTML element with the <span> tag and the CSS class mw-page-title-main. The find() method returns the first occurrence of the element that matches the specified tag and class criteria. If no matching element is found, the find() method returns None. The result of this search is assigned to the variable title_element. Depending on the situation use find() or find_all()

8. print(title_element): We print the value of title_element. This will display the entire HTML element (i.e., the <span> element with the class mw-page-title-main).

9. print(title_element.text.strip()): We access the text content of the title_element using the .text attribute. The .text attribute returns the text content of the HTML element, excluding any HTML tags. The strip() method is then applied to remove any leading or trailing whitespaces from the extracted text content. Finally, we print the result, which is the main title of the web page without any unwanted whitespace.

This is how you can scrape a static website, lets now look into how we could scrape dynamic websites.

6. Scraping for Dynamic Website

We will scrape data from a dynamic website, where content is loaded using JavaScript. For this purpose, we will use Selenium. There are times when the scraping requires you to interact with the websites dynamically, hence we use webdrivers to achieve this.

options = Options()
options.add_argument('--headless')
browser = webdriver.Chrome(options=options)
browser.get(url)

page_source = browser.page_source

browser.quit()

soup = BeautifulSoup(page_source, 'html.parser')

In this code snippet, we are using Selenium to scrape data from a dynamic website, where content is loaded using JavaScript. Here’s an explanation of the steps:

options = Options(): We create an instance of the Options class from Selenium. This allows us to set various options and preferences for the web browser we are using with Selenium.
options.add_argument(‘–headless’): We set the option –headless, which runs the browser in headless mode. Headless mode means the browser runs without displaying a graphical user interface (GUI), providing a more efficient and faster way to scrape data without the need for a visible browser window.
browser = webdriver.Chrome(options=options): We create an instance of the Chrome WebDriver using the webdriver.Chrome() method and pass the options object we created earlier. This sets up the Chrome browser in headless mode with the specified options.
browser.get(url): We use the get() method to navigate to the URL of the dynamic website. The browser will load the webpage and execute any JavaScript code, which may load additional content dynamically.
browser.quit(): Once the details are extracted, we can close the browser, since no more interactions with the website is necessary.
page_source = browser.page_source: We retrieve the page source of the loaded webpage using the page_source attribute. The page source contains the entire HTML content of the webpage after JavaScript execution, including any dynamically loaded content.
We later use BeautifulSoup to parse the details, same as the previous procedure

7. Advanced Scraping

This section will cover more advanced techniques, such as handling pagination

options = Options()
options.add_argument('--headless')
browser = webdriver.Chrome(options=options)
browser.get(url)

button = WebDriverWait(browser, 10).until(EC.visibility_of_element_located((By.XPATH, “XPath_Class”)))

button.click()

page_source = browser.page_source

browser.quit()

soup = BeautifulSoup(page_source, 'html.parser')

In web scraping, pagination refers to the practice of dealing with websites that display data across multiple pages. Instead of showing all the information on a single page, the website splits the data into several pages to improve readability and load times. Handling pagination is essential when you want to scrape data from all the pages of a website.

All steps are similar to the previous codes, but here we have added a button,

button: Here, we create an instance of WebDriverWait, which allows us to set a maximum waiting time of 10 seconds (10 in the code) for an element to become visible on the page. We pass two arguments to WebDriverWait: the browser object, which represents the current browser instance, and the expected condition (EC) that we want to wait for. In this case, we are waiting for the element located by the XPath “XPath_Class” to become visible on the page.
button.click(): Once the button element is visible (and the WebDriverWait stops waiting), we use the click() method on the button object to simulate a click on the button. This will trigger any associated JavaScript actions on the webpage, such as loading additional content or navigating to another page.

Hence with the various use cases and techniques covered in web scraping, you gain the ability to accomplish remarkable tasks. However, it is crucial to remember that the success of your web scraping endeavours depends on understanding when to employ the appropriate approach for different scenarios. In this blog I have covered only the necessary aspects. Being mindful of these aspects will ensure that you choose the right tools and methods, making your web scraping process more effective, efficient, and responsible.

Conclusion
