Data scraping typically involves the following steps:
1. Retrieving the HTML: The first step is to fetch the HTML code of the web page(s) from which you want to extract data. This can be done using tools or libraries that can send HTTP requests to the website and receive the HTML content in response.
2. Parsing the HTML: Once the HTML content is obtained, it needs to be parsed to extract the relevant data. Parsing involves analyzing the HTML structure to identify the specific elements, such as tags, classes, or IDs, that contain the desired data.
3. Extracting the data: After identifying the relevant HTML elements, the data can be extracted by applying techniques like using XPath or CSS selectors to target specific elements and retrieving their content. This could include text, images, links, tables, or any other data present on the web page.
4. Extracting the data: After identifying the relevant HTML elements, the data can be extracted by applying techniques like using XPath or CSS selectors to target specific elements and retrieving their content. This could include text, images, links, tables, or any other data present on the web page.
It's important to note that while data scraping can be a useful technique for collecting data, it is crucial to respect the legal and ethical considerations. It is essential to check the website's terms of service, understand any restrictions, and ensure compliance with applicable laws and regulations.
