Selenium refers to a number of different open-source projects used for browser automation.
In order to install the Selenium package, as always, I recommend that you create a virtual environnement, using virtualenv for example, and then:. Once you have downloaded both Chrome and Chromedriver, and installed the selenium package you should be ready to start the browser:. This will launch Chrome in headfull mode like a regular Chrome, which is controlled by your Python code.
You should see a message stating that the browser is controlled by an automated software. In order to run Chrome in headless mode without any graphical user interfaceto run it on a server for example:. There are many methods available in the Selenium API to select elements on the page.
You can use:. We recently published an article explaining XPathdon't hesitate to take a look if you aren't familiar with XPath. As usual, the easiest way to locate an element is to open your Chrome dev tools and inspect the element that you need.
Web Scraping using Selenium and Python
There are many ways to locate an element in selenium. Let's say that we wan to locate the h1 tag in this HTML:. Some element aren't easily accessible with an ID or a simple class, and that's when you need an XPath expression. You also might have multiple elements with the same class the id is supposed to be unique. XPath is my favorite way of locating elements on a web page. It's very powerful to extract any element on a page, based on it's absolute position on the DOM, or relative to another element.
Only use this feature in order to get customized results, do not use this feature in order to avoid blocks, we handle that internally. The value of session can be any integer, simply send a new integer to create a new session this will allow you to continue using the same proxy for each request with that session number. Sessions expire 60 seconds after the last usage. United States us geotargeting is available on the Startup plan and higher. Other countries are available to Enterprise customers upon request.
Our standard proxy pools include millions of proxies from over a dozen ISPs, and should be sufficient for the vast majority of scraping jobs. However, for a few particularly difficult to scrape sites, we also maintain a private internal pool of residential and mobile IPs. This pool is only available to users on the Business plan or higher.

If you would like to monitor your account usage and limits programmatically how many concurrent requests you're using, how many requests you've made, etc.Web sites are written using HTML, which means that each web page is a structured document.
This is where web scraping comes in. Web scraping is the practice of using a computer program to sift through a web page and gather the data that you need in a format most useful to you while at the same time preserving the structure of the data. We will also be using the Requests module instead of the already built-in urllib2 module due to improvements in speed and readability. You can easily install both using pip install lxml and pip install requests.
Next we will use requests. We need to use page. In this example, we will focus on the former. A good introduction to XPath is on W3Schools. Knowing this we can create the correct XPath query and use the lxml xpath function like this:. We have successfully scraped all the data we wanted from a web page using lxml and Requests.
We have it stored in memory as two lists. Now we can do all sorts of cool stuff with it: we can analyze it using Python or we can save it to a file and share it with the world. Some more cool ideas to think about are modifying this script to iterate through the rest of the pages of this example dataset, or rewriting this application to use threads for improved speed. This opinionated guide exists to provide both novice and expert Python developers a best practice handbook to the installation, configuration, and usage of Python on a daily basis.

This chapter will give you an in-depth idea of web scraping, its comparison with web crawling, and why you should opt for web scraping.
You will also learn about the components and working of a web scraper. Here two questions arise: What we can get from the web and How to get that. Data is indispensable for any programmer and the basic requirement of every programming project is the large amount of useful data. The answer to the second question is a bit tricky, because there are lots of ways to get data. In general, we may get data from a database or data file and other sources. But what if we need large amount of data that is available online?
One way to get such kind of data is to manually search clicking away in a web browser and save copy-pasting into a spreadsheet or file the required data. This method is quite tedious and time consuming. Another way to get such data is using web scraping.
Web scrapingalso called web data mining or web harvestingis the process of constructing an agent which can extract, parse, download and organize useful information from the web automatically.
In other words, we can say that instead of manually saving the data from websites, the web scraping software will automatically load and extract data from multiple websites as per our requirement. The origin of web scraping is screen scrapping, which was used to integrate non-web based applications or native windows applications. The terms Web Crawling and Scraping are often used interchangeably as the basic concept of them is to extract data.
However, they are different from each other. We can understand the basic difference from their definitions. Web crawling is basically used to index the information on the page using bots aka crawlers.
It is also called indexing. On the hand, web scraping is an automated way of extracting the information using bots aka scrapers. It is also called data extraction.
The uses and reasons for using web scraping are as endless as the uses of the World Wide Web. Web scrapers can do anything like ordering online food, scanning online shopping website for you and buying ticket of a match the moment they are available etc.
The crawler downloads the unstructured data HTML contents and passes it to extractor, the next module. The extractor processes the fetched HTML content and extracts the data into semistructured format.
The data extracted above is not suitable for ready use. It must pass through some cleaning module so that we can use it. The methods like String manipulation or regular expression can be used for this purpose.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Feb 1, May 6, Added latest argument to only scrape new media since last scrape reso…. May 1, In this tutorial, we will build an Amazon scraper for extracting product details and pricing. We will build this simple web scraper using Python and SelectorLib and run it in a console.
Skip the hassle of installing software, programming and maintaining the code. Download this data using ScrapeHero cloud within seconds. We will use Python 3 for this tutorial. The code will not run if you are using Python 2. To start, you need a computer with Python 3 and PIP installed in it. But, not all the Linux Operating Systems ship with Python 3 by default. If the output looks something like Python 3. If it says Python 2.
After downloading the SelectorLib extension, open the Chrome browser and go to the product link you need to markup and extract data from. We have named the template amazon. Next, we will add the product details one by one. Select a type and enter the selector name for an element. The GIF below shows how to add elements. We are adding this extra section to talk about some methods you could use to not get blocked while scraping Amazon.
Okay, how do we do that? Let us say we are scraping hundreds of products on amazon. The rule of thumb here is to have 1 proxy or IP address make not more than 5 requests to Amazon in a minute. You can read more about rotating proxies here. If you look at the code above, you will a line where we had set User-Agent String for the request we are making.
Just like proxies, it always good to have a pool of User Agent Strings. Just make sure are using user-agent strings of the latest and popular browsers and rotate the strings for each request you make to Amazon.
