I’m still getting acquainted with both JavaScript and Puppeteer, and I’m looking for a method to extract data from an HTML table. Specifically, I need to obtain all the rows of the table using the <tr> tag, particularly those rows where each cell includes a specific class defined in a <td> tag, for example, <td class="customCell">. The table layout I’m working with resembles a standard grid format. Could anyone provide insights or demonstrate a sample approach to efficiently target and scrape these table elements using Puppeteer?
In my experience, a robust way to extract table rows with Puppeteer was to use page.evaluate to run DOM methods directly in the browser context. I usually select all the rows using document.querySelectorAll(‘tr’) and then filter for those containing a element with the desired class by checking if row.querySelector(‘td.customCell’) exists. This flexible method allows me to perform any additional filtering or data extraction within the same script. Running the extraction on the page itself tends to be much faster and more reliable than making multiple page requests.
