*About XPath*
You don’t need to fix the Xpath each time. But you do need to check if it has been correctly set up. If you click through the workflow, and the web browser does the corresponding reaction, it means it is correct. In this case, as you click through the workflow, you will notice from the setting area that says “cannot locate the element with existing XPath expression. And the built-in browser doesn’t paginate to the second page. This means we need to fix the Xpath and to tell Octoparse to locate the” NEXT PAGE” button precisely.
