login to websites, click on maps and handle sites with infinite scroll. The scheduled extraction based on cloud platform is only for premium users. We have vastly simplified the problem of delivering, maintaining, and governing. And what you need to do is just export all the data after the extraction is done. Octoparse allows you to schedule an extraction task to run at any time, hourly, daily, weekly etc. What if you want the everyday top news of a week? It is definitely not a good idea to run the task every day by yourself. (See the example tutorial here)Īs for websites such as news webs, the content changes daily. You can set the scroll times, time interval and scroll way (scroll to the bottom or scroll one screen) according to the website you extract. It also allows you to maximize your productivity. Octoparse can easily scrape those websites with different functions like scrolling down the page or AJAX Load. It is convenient for users to view more data on such kind of websites but not for scrapers. The API will not need to manually access the app to control your crawlers and data collection. Examples are lazy loading images, infinite scrolling and show more info by clicking a button via AJAX calls. Using API-The Octoparse API makes the process of data acquisition automatic. This case can be easily handled by setting "Scroll Down" of " Go To Web Page" action with Advanced Mode. It is possible because it has features such as infinite logging in and scrolling. Let me give you a for-instance - Twitter, which load infinite content if you keep scrolling down to the bottom of the screen. In this short tutorial, I'm going to show you how to deal with infinite scrolling or clicking to load more on a dynamic website. This sort of websites may have infinite scrolling techniques such as clicking to load more or scrolling down, like Facebook or Twitter. A dynamic website contains information that changes very frequently, usually generated by users. It could only be updated with knowledge of website development. A static site is one of which the content does not change, for example a yellow page of a company. When dealing with issues like missing data, endless loop, incorrect data, duplicative data, next button not getting clicked, etc, there's a good chance you'd fix these issues easily by re-writing the XPath. That's why we need to learn to rewrite XPath. It can handle infinite scroll, pagination, custom Javascript execution. Sounds complicated? No worries, let's dive into an example.Websites can be static and dynamic. Octoparse can generate XPaths automatically but the auto-generated ones do not always work well. UI isnt as good as Parsehub and OctoparseMiner is another software very. Check out What is XPath and how to use it in Octoparse to learn more about using XPath to create the perfect web scraper. To get started, download and install Octoparse on your device. Follow this step-by-step guide to scrape Trustpilot reviews Step-1 Set up your Octoparse environment. TIP: XPath knowledge is not mandatory but is extremely helpful to create a task that does exactly what you need in Octoparse. It also offers sophisticated functionality to handle login, AJAX, JSON, infinite scrolling, and other issues for more complex websites. STEP 2: Revise the XPath of the Pagination in the workflow in Octoparse. STEP 1: Write/find the XPath of the page element that takes you to the next page (e.g., if you are on page 1, then you would want to click page 2 if you are on page 2, then you would like to click page 3, so on and so forth). Once you have the links generated, Octoparse will go on to scrape all the pages automatically.Įven if the Auto-detect fails to work and page URLs do not show a pattern, you can still manually create a pagination action. If you see a similar pattern to the example above, with only the page number changing in the URLs of the different pages, you can easily batch generate all the page URLs and scrape as many pages as needed.
