Subsequently, the variable holding the extracted data will be of type List. If you choose to retrieve all the product names displayed in the page then you'll end up with a list. You are no longer in the page containing the product info, but in a page containing the list of all products. You will be able to access each one of the retrieved values using the following form: %DataFromWebPage% where within the brackets you will enter either a number or the name of the value. In this case three separate values will be extracted and the resulting variable will hold a value of type DataRow. Say that, in our previous example you select to extract not only the product name, but also the description and its price. In this case, if the extracted data is stored into a variable this variable will contain a text value. Say that from a web page containing info about a product, your extract the product name only. Note that the extracted data can be in any of the following forms:
The default value is to be written into a newly generated Excel spreadsheet, but to do so you need to have Microsoft Excel installed in your computer.Īlternatively you can have the data stored into a variable for further processing by later actions. The next step is to specify the data itself and finally to select where the extracted data will be stored. And this is where the " Extract Data from Web Page" action comes into play:Īs with any other web-related action you will first need to specify the web browser instance containing the page you want to extract data from. So far so good, however, very often, you want to retrieve information displayed into the page in the form of tables or lists, rather than technical values. The other actions allow you to take a screenshot of a web page element, retrieve details of a web page such as its title or its HTML source and finally retrieve any HTML attribute of any web page element or even its text. In WinAutomation there are four actions dedicated to this task, with " Extract Data from Web Page" being the more important and versatile. Extracting data from web pages is a big part of Web Automation.
