Handy Web Extractor

Handy Web Extractor is a simple tool for everyday web content monitoring. It will periodically download the web page, extract the necessary content and display it in the window on your desktop. One may consider it as the data extraction software, taking its own nitch in the scraping software and plugins.

What is it for?

Have you ever needed to track some web site changes without visiting it again and again? If so, you may find this program useful. The idea is simple: it periodically downloads the specified web page, extracts the part you need and displays it for you in a small window. You can easily move, resize, hide or show this window according to your needs.

It’s totally free and available for download.
How does it work?

After installing the program you will see the following window:


At the top of the window (on white background) you may see the extracted web page itself (in this case it’s a header of this article) followed by program settings (on light yellow background). If you don’t see the program settings click on the gear icon (if you want to hide them click it again).

Settings available:

    Web Site URL – type the URL of the target web-page you want to scrape
    Extract using XPath – use this option if you want to specify the portion of the web-page using XPath expression
    Extract using Regex – use this option if you want to specify the portion of the web-page using Regex expression
    Update every N min - to specify how often the program will scrape the target website
    Autostart – check this box if you want the program to start automatically when Windows starts

After you change either the web site URL or XPath/Regex expression click the “Update now” link at the bottom to rescrape the web site.

You may always access this window via the “magnet” icon in the system tray. Click the icon to show/hide the window and right-click it to display an additional menu.

That’s it. The only thing I’d like to mention here is that the program remembers all your settings right away (including window position and size) and you don’t need to “save” them manually.
