| | Screen scraping - Wikipedia, the free encyclopedia |
 | | The key element that distinguishes screen scraping from regular parsing is that the output being scraped was nominally intended for human consumption, not machine interpretation. |
 | | In all cases, the screen scraper has to be programmed to not only process the text data of interest, but also to recognize and discard unwanted data, images, and display formatting. |
 | | The screen scraper might connect to the legacy system via Telnet, emulate the keystrokes needed to navigate the old user interface, process the resulting display output, extract the desired data, and pass it on to the modern system. |
