Web Scraping Tools, Libraries, and Frameworks for Data Extraction

Web scraping tools include crawling frameworks, HTML parsing libraries, browser automation tools, and visual scraping software. Before collecting data, review applicable laws, website terms, privacy requirements, and access restrictions. The Robots Exclusion Protocol should also be respected; however, robots.txt does not grant or deny legal authorization by itself.

Scrapy

It has been developed and released under open-source licenses and continues to be developed collaboratively. This is because it is relatively fast, and large-scale web scraping can be customized in the language using performance scaling.

Features:

• Supports CSS and XPath selectors for data extraction.
• Processes and stores data through item pipelines.
• Exports data in formats such as JSON, CSV, and XML.

Beautiful Soup

It is a Python library with a number of unique features, making it suitable for rapid prototyping and quick-and-dirty projects such as screen-scraping. It makes a parse tree of web page source codes, which makes the extraction of data from them easy.

Features:

• Searches and navigates HTML and XML elements.
• Supports multiple parsers.
• Works well with an HTTP client for extracting data from downloaded pages.

Features:

• Automates supported web browsers.
• Supports languages such as Python, Java, C#, and JavaScript.
• Interacts with dynamically rendered web pages.

Puppeteer

Puppeteer is a Node.js . library that offers a set of methods and functions that allow you to manage a headless Chrome or Chrome browser. That is being used in web scraping and testing of web applications.

Octoparse

Octoparse is a visual web scraper, which means one does not need to know any coding to scrape data from websites. It provides a simple and intuitive front-end and highly scalable extraction on the back end, based in the cloud.

Features:

• Visual, no-code extraction workflows.
• Supports extraction from suitable dynamic websites.
• Offers cloud execution and scheduled tasks on eligible plans.

Features:

• Provides visual data extraction.
• Handles supported dynamic pages and interactive elements.
• Supports data export and API access.

WebHarvy

WebHarvy is a web scraping tool that acts like a mouse click for a programmer who does not know how to code. While with Scrapy, developers are able to scrape the data by defining the specific site’s structure, with ContentSpider, it lets the users select the data elements they want to get.

Features:

• Provides visual data selection.
• Supports configurable extraction workflows.
• Offers scripting and data-processing options.

Content Grabber
