This extension uses the Helena web automation language to scrape data from well-structured webpages.
Helena is a high-level programming language for web automation. It comes with a programming-by-demonstration (PBD) tool for writing Helena programs. Just open the browser extension, demonstrate how to collect the first row of a dataset, then let Helena write a program for collecting the remaining rows.
Note: Helena is still a research prototype! We're still researching how to teach this PBD tool and how to improve the user interface. For now, the best way to tackle any problems that you run into is to get in touch with the research team. Find us at http://helena-lang.org/.
