A table is one of the most common forms of data display on the web. To do this, we will split the extraction process into 2 steps. Though there is some information such as the product title, model number, etc available directly from the list, but when we want something more specific such as the features or the specification of the products, we will actually need to click on the links from the list then go on to capture the desired data from the detail page. When more detailed is needed, it is often required to click on the links from the list then capture the detailed information from the detail page. If after two clicks, there are still sections needed but have not been selected automatically, you can keep clicking on the un-selected sections to help Octoparse refine the list. For extracting detailed information from each individual section of a list, we will split the extraction process into two steps.
