The site provides payroll data for the State of Kansas. Yet, like many government websites, it buries the data in drill-down links and tables. I wanted to use the public data provided for the universities within Kansas in a research project.
Web scraping with Python often requires no more than the use of the Beautiful Soup module to reach the goal. Beautiful Soup is a popular Python library that makes web scraping by traversing the DOM document object model easier to implement.
For Selenium to work, it must access the browser driver. By default, it will look in the same directory as the Python script. Links to Chrome, Firefox, Edge, and Safari drivers available here. The example code below uses Firefox:. Beautiful Soup remains the best way to traverse the DOM and scrape the data. After defining an empty list and a counter variable, it is time to ask Beautiful Soup to grab all the links on the page that match a regular expression:.
Beautiful Soup will then retrieve the table from each page. Beautiful Soup passes the findings to pandas. The dataframe is appended to the previously defined empty list. Before the code block of the loop is complete, Selenium needs to click the back button in the browser.
This is so the next link in the loop will be available to click on the job listing page. Beautiful Soup has retrieved the table from each page. Pandas has stored the data from each table in a dataframe.

I'm struggling to open chromium-browser so that automatically goes to a URL I give it. After searching on the internet I started using selenium and managed to get the browser to open but it wont go to any URL I pass.
The current code in my Python file is:. This half works and opens chromium but doesn't then go to the 'station' I provided. Any ideas on how to fix this? In case I would replace 'browser' with 'driver' I would get tons of errors. I was close to give up because elsewhere I found statements, that selenium dos not support raspberry resp chromium-browser anymore.
I am using a script to auto-connect after boot to the wifi network in my apartment. The lines above are the first commands. In case of 'connection' that happens sometimes the script stops.
In case of 'no connection' the login-form is being filled and submitted by further code, which is not displayed here. Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered.

Selenium refers to a number of different open-source projects used for browser automation. It supports bindings for all major programming languages, including our favorite language: Python. The browser can run either localy or remotely.
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. 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.

In our example, authenticating to Hacker news in itself is not really useful but you could imagine creating a bot to automatically post a link to your latest blog post for example.
Easy right? Now there is one importing thing that is missing here, how do we know if we are logged in?
In order to automate Chrome Browser we must have Chrome web driver. The path, where web driver file is placed, is passed as argument. Web driver interacts with the web browser through a protocol.
After installing the required modules, you can open python CLI and start playing with your browser. This will open up a new Chrome browser window for you. Now you can get selenium to go to any website using. This method opens the website and will wait for it to load, then you can enter your next command.
To copy XPath, right click on highlighted source code on source page. By using the above methods, we can locate an element on a web page and use it in our automation code. Selenium also has a module that lets you send special keys e. You need to import this module using the following command. You can automate by sending this key to browser using Selenium.
With web automation, you can easily make your logging in process automatic. If you check your social media websites at specific time say 8 pm regularly then it is good to automate this process. Above code automates the browser to log into social media websites. First of all we created an object of our favourite browser.
Then we entered the url of facebook and logged into Facebook by selecting elements and passing username and password. After this we opened a new tab and entered the url of twitter. After this we switched to the new tab as the control of the code was still on first tab although the second tab was open.
Then we logged into twitter by selecting elements and passing username and password. Another good example of browser automation could be the online shopping.
For example, you want to buy a camera online but the prices are too high. You check everyday whether the price is in your range or not.
Following code will inform you through mail whether the price of your desired product is affordable or not. If your desired product is on sale, the program will notify you via an email. Above code opens daraz. Then we locate our desired product using elements and their attributes.
How elements are found and located, has been described above. The price we got was a string so we converted this string into integer and then checked whether the price is affordable or not. Above two automation scripts are required to run once a day at a specific time. We can manage this using cron job. Tasks, which are added to crontab can be run at a specific time repeatedly.
To add above tasks in crontab, first of all run the following command in Linux Terminal. Above command will open crontab file to edit.

Selenium ChromeDriver – 2 ways to launch Chrome
I am using Selenium RC to automate some browser operations but I want the browser to be invisible. Is this possible? What about Selenium Grid? Can I hide the Selenium RC window also? You could use Selenium Grid so that the browser is opened on a completely different machine or virtual machine that you can then connect to via VNC or Remote Desktop Connection if you wanted to see the browser.
Also, another option: if you run a Jenkins foreground process on that remote server, it can execute your test project on the desktop. I've never tried doing this and doubt it's really worth the effort. You can wrap Selenium RC in a Windows service. Except that permissions constraints on later versions of windows will probably prevent Selenium from accessing the desktop like Windows used to allow us to do.
Also there is a PhantomJS option as well as a 'headless Chrome' that you could use. Of course there's also the option of using a service like SauceLabs, where you can get your tests to be run in the cloud. After your tests have completed you can watch a video of them running.
On Linux, you can run WebDriver in a headless virtual display to hide the browser. This can be done with Xvfb X virtual framebuffer. Just install PhantomJS. Then, change this line:. The rest of your code won't need to be changed and no browser will open. For debugging purposes, use driver. For having the tests run completely hidden, I think you don't have much solutions if you're on windows.
So you use that computer's IP instead of localhost to run your tests. For example:. Having that setup, you run your tests in you computer, the browsers and the RC server window are in another computer and the go back to yours once done. On Linux, you can run your test browser on a virtual display. You will need the xvfb package for creating a virtual X server. On Debian based distros, just run. There is a nice tool ephemeral-x. Download it and make it executable:.
All browser windows created by Selenium will now use the virtual display and will be invisible to you. If you're on Windows, one option is to run the tests under a different user account. This means the browser and java server will not be visible to your own account. This is how I run my tests with maven on a linux desktop Ubuntu.
I got fed up not being able to work with the firefox webdriver always taking focus.This article provides a detailed guide where you will learn how to download the latest version of Selenium ChromeDriver.
You will also see how you can setup Selenium ChromeDriver in multiple ways, and then write code which can launch Chrome browser using Selenium. Note: This article is a part of our Selenium Tutorial series. Please make sure that you have installed the latest version of Selenium WebDriver in order to avoid compatibility issues with Chrome.
In this article, we will work with the latest and stable versions of Selenium, ChromeDriver and Google Chrome. The versions that we are going to use are —. Before we begin, let us check out some basics of ChromeDriver. When you write test scripts in Selenium, you use WebDriver to launch and communicate with different browsers. You will generally do this with the below line of code —.
Let us see the steps that you can follow to download Selenium ChromeDriver —. This page contains all the versions of Selenium ChromeDriver. We are interested in the latest version of ChromeDriver, which is ChromeDriver 2. Click on ChromeDriver 2. Once the zip file is downloaded, you can unzip it to retrieve chromedriver. This completes the Selenium ChromeDriver download process. Let us see how you can setup ChromeDriver in your project.
As shown in the below image, this can be done in 2 different ways —. If you have worked on Selenium automation before with some different browsers, then you would have realized that these 2 methods of setup are similar to what you do with other WebDriver variants.
Let us have a detailed look at each of these steps one by one. With this method, you will have to add an additional line of code in your test case. Follow the steps given below to use this method —. Copy the entire path where you unzipped chromedriver. You will need to add System.
Run this code to verify that it works fine. It launches a new browser window and opens google. This message would come up every time you launch Chrome. To remove this message, you would need to use disable-infobars argument from ChromeOptions class in your code. The code snippet for this is given below —.
