How do I use data scraper in Chrome?
I am new to web scraping and I have searched for the answer to this question but haven't been able to find any good information. I would like to scrape a URL from the page of my current web browser using data scraper in Chrome (I am using Windows 10) and have it download a file to a given location on my hard drive. I am currently using an online data scraper to scrape URLs from a website I own, but the website is behind a paywall so I can't use that to scrape directly from the webpage. I have searched for ways to do this but haven't found a good resource that works in the current version of Chrome.
As far as I know Chrome doesn't support Data Scraping API. But there are couple of ways to scrape.
Download chrome extension called Page Scraper and scrape the URL by default.
How do you use data scraper?
How to Build a Web Scraper. We're going to walk you through the process of building a web scraper using the Python programming language. We're not going to go into too much detail in the first part of this article, but we will start to explain the fundamentals of web scraping and how to write your own web scraper. In Part 2 of this tutorial series, we'll discuss what makes a good web scraper, learn about the fundamentals of scraping HTML data, and learn how to build a web scraper using Python.
If you've never scraped data from a website before, it's important to understand that a scraper is different from simply grabbing some text from a website and storing it in a file. A scraper is actually an automated process that uses code to interact with websites, extract data from the site, and then save the data to a file. This data can then be processed or analyzed using other tools. You might want to read our previous article for more information on why web scraping is so useful in business.
Before you start scraping data from a website, it's important to understand the difference between web scraping and simply grabbing data from a website. The first thing you need to do is decide whether you'd like to scrape HTML or just grab text data from a website. For most people, it's easiest to use a combination of Python and Selenium. Selenium is a web driver that allows you to control the browser using Python. There are two approaches to building a web scraper: you can either use a simple web crawler or use Selenium and PhantomJS. The method you choose really depends on how much you want to automate your scraping process and how much time you have to dedicate to learning how to use these tools.
For this tutorial, we're going to focus on using Python, but it's worth noting that many other programming languages exist that allow you to scrape data from websites. If you're interested in learning how to scrape data from a website using Python and Selenium, check out the links at the end of this article.
Getting Started with Python. You'll need to first download and install Python.
Is instant data scraper safe?
There are a lot of reasons to use an instant data scraper. You could do it from one or a series of windows one or several computers in your office without fear that you would run out of processing power to finish the scraping for all those computer(s).
But, this type of data scraping may turn out to be a problem, especially if you try to scrape data too much. It might be even more difficult for you to stop when the scraping becomes too noisy - you might risk a crash of your whole data scraper. This is when you start getting into scraping errors and you wonder: Will my real, live data scrape ever crash? And should I bother with a backup plan just in case? The answer is: yes. Always make sure you have some back up plan in place before attempting to scrape (and, if not, at least start by testing your data scraper first in a safe virtual environment so you don't waste a lot of time scrapping data).
Do I want to scrap data and store it in MongoDB, SQL Server or Google Drive? Or do I just want to export a local copy of the data right away for archiving purposes (backup purposes)? If you just want to export your scraped data to local folders, Google's Datastore or Amazon's S3 cloud services could be good alternatives. In this case, data scraping means importing or scraping into Google's or Amazon's datastore and then downloading to a local storage folder or S3 bucket. To be honest, this is almost as easy as using an instant data scraper and you don't have to worry too much about the performance of your scraping operation itself, only of the data export afterwards, either directly or after a delay.
In case you actually want to store your scraped data (by either creating a web app or using an API), your choice will come down to one of two options: either you store it in a Google's document-centric database (Datastore), or you store it in a database such as SQL server or MongoDB. The decision whether to use this alternative depends on your particular circumstances, and is a decision best made based on cost vs value and/or risk to reputation of you and your organization.
