XPath is a language that allows you to locate specific elements from a web page. Modifying XPath in Octoparse works very well with more flexibility and accuracy than the XPath auto-generated by clicking elements during the task configuration.
Octoparse allows you to customize the element XPath so that you can precisely locate the data you are targeting. This helps resolve any issue as data missing, page skipped, blank fields, and duplicates.
