![]() ![]() Actually, it’s somewhat similar to handling frames. When this happens, it’s important to know how to go from tab to tab in order to get the data you need.įortunately, handling tabs with Selenium is not a complex process. How to Switch TabsĪnother common situation you might face when navigating through a website to collect data is that a button automatically opens a new tag. print(len(frames))Īnd now you are free to interact with the page and collect the data you need. To find out how many frames are on the page, just print the length of the frames object. This is how it would work: frames = driver.find_elements_by_tag_name('iframe') You can also use the index of the frame to make the switch: driver.switch_to.frame(0)īut if you don’t know the name of the frame or how many frames there are on the page, the solution is to find all the frames on the page and then print the name of each one of them. If you know the name of the frame, just do this: driver.switch_to.frame('mainIframe') To fix the problem, you only need to switch to the correct frame before you try to interact with the page again. We use HTML frames to divide the page into sections that each load a different part of the content. ![]() The data you want to collect or the element you want to interact with is just in another frame on the page. So what’s wrong?Īctually, nothing is wrong. So you check over and over for errors in the code but everything seems to be just fine. No matter how you try to do it – by using the Xpath, or the class name, or whatever – you keep getting errors. You may have found yourself in a situation where you just cannot make Selenium find a particular element on a webpage. check_box = driver.find_element_by_xpath('Xpath')Īnd then, after the cursor has been moved, you just need to perform a click and the check box will be marked. To find the appropriate distance for the move, execute the code with the size attribute of the element before running the complete code. The goal is to have the cursor around the middle of the check box. ![]() You need to inform the element and the distance you want the cursor to move away from the top-left corner. The move_to_element_with_offset method will move the mouse by an offset of a specific element on the page, relative to its top-left corner. This is the code to do that: check_box = driver.find_element_by_xpath('Xpath')Īctions.move_to_element_with_offset(check_box, -5, 5).perform() The workaround for this is to locate the element and use an ActionChains object to move the cursor to the check box and then click on it. So when you try to click on it, an exception will be raised. For most websites, Selenium won’t recognize a checkbox as a clickable button. That’s because you might think that all you need to do is to locate the element using its Xpath and then use the click method to click on it.Īnd, yes, depending on the website that may be the case – but it’s not a rule. Marking a check box may seem like a very simple action, but it can be a little tricky. ![]() And when going through the website, you may need to fill out some forms, click on one or two buttons, and mark a check box, for example. Sometimes you need to navigate through the website to get to where the data is. The process of scraping data doesn't involve only scraping the data. Scraping is fun and a great way to gather data, but it needs to be done in a correct legal, manner. Also, it's a good practice to configure your scraper in order not to overload the website's server as we don't intend to cause any harm. It will cover three helpful topics to give you more options when you're interact with a website in order to access its content.Īnd although this article focuses on web scraping, that’s only one use case for these tips as you can implement them for any tasks where Selenium is useful.īefore we start, an important disclaimer: before beginning to scrape any website, make sure to check if the website allows you to do so. This article is about the second capability – interacting with the page however you want. This is because Selenium can do things that other libraries or frameworks often can't when collecting data: accessing JavaScript-rendered content and interacting with the page in basically any way you want. It was originally designed for automated testing, but its scraping capabilities are impressive, too. When you're scraping data from the web with Python, Selenium will often come up as an helpful tool to use. ![]()
