Scrape Webpage Data Using Auto-detect Algorithm

In this article, we will explore the process of scraping webpage data using the auto-detect algorithm in Octoparse 8. This algorithm is specially designed to handle webpages with nested lists and various other elements. By the end of this article, you will have a clear understanding of how to use this feature efficiently and extract data from any website you want.

Step 1: Create a New Task

The first step is to create a new task in Octoparse. Simply enter the URL of the webpage you want to scrape into the search box and click "Start" to initiate the task creation process.

Step 2: Get Data via Auto-detect

Octoparse will then load the webpage URL in the built-in browser and start the auto-detect process. This process may take some time, so it's important to be patient. Once the process is complete, you will be provided with more information in the "Tips" panel.

Step 3: Check the Data

After the auto-detection process is finished, it's time to check the data that has been extracted. Follow the instructions provided in the "Tips" panel and review the data in the preview section. You can also make adjustments, such as renaming data fields or removing unnecessary ones.

Step 4: Confirm Your Options

In this step, you need to confirm your options based on the type of data detected. Octoparse provides you with several choices to select from. If the auto-detection has identified list data, you will have the option to extract the data in the list. Additionally, if there is a "Next" button on the page, you can choose to click it and capture data from multiple pages. You can also choose to click on the links detected to extract more information from detail pages.

Step 5: Save Task Settings

Once you have confirmed your options, it's time to save your task settings. Octoparse will automatically generate a workflow based on the data detected and the settings you have chosen. At this point, you have the option to run the task immediately or edit the workflow manually. When everything looks good, you can save and run the task to start extracting your desired data.

In conclusion, using the auto-detect algorithm in Octoparse 8 allows you to scrape webpage data effortlessly. With the step-by-step guide provided in this article, you should be able to successfully extract data from any website you want. So go ahead and give it a try!
