Every item in the list will be assigned to a cloud server to shorten the extraction time. These three modes are often used in Cloud Extraction to speed up the extraction process. Click here to see an example.įixed List, List of URLs, and Text List are all used to make a list with a certain number of items. Text List Mode is used when you need to enter different text values, for example, entering different keywords in the searching box. It can be used when you have many pages with similar formats like Amazon product detail pages. List of URLs is to make a list of URLs for Octoparse to browse one by one. Any suggestions I have tried the following XPath (along with a few other failures): // id'main'/div 2/section/div 1/nav/ul/li 1/a. I am trying to scrape data from each page. The website pages do not have a 'Next' button. I can't seem to get my XPath right for pagination. The items added to the list will not change even in dynamic pages. I am trying to scrape a few company websites with Octoparse. Click here to see an example.įixed List is opposite to Variable List as it can not automatically add new items but just add items according to the fixed list of XPath you enter the box. Using the XPath contains () function, we can extract all the elements on the page that match the provided text. Contains function has two arguments as a String and is much preferred for a part of a value. Single Element is to locate just one single item matched with an XPath, especially to normal pagination by loop clicking a button. Xpath Contains is an XPath function that is used to find Dynamic web elements and returns a partial attribute value to locate the web element. That is what Variable List Mode can do for you! Every time there are new tweets shown, Octoparse will automatically add them to the list right away. So you need to keep adding new tweets shown on the page to the loop list. For example, there will be more tweets on the same twitter page if you keep scrolling down to the bottom of the screen. With the powerful XPath selector, it could specify. It is widely used to locate items in a similar layout, especially when dealing with dynamic websites because Variable List Mode will automatically detect and match all the items corresponding to a certain XPath. Great web scraping tool to extract data online Pros: Octoparse is able to extract almost every website.
Variable List is the most frequently used loop mode in Octoparse. There are actually 5 loop modes in Octoparse: Variable List, Single Element, Fixed List, List of URLs, and Text List.
