This Firefox add-on enables Xqueries to be performed directly within the browser.
The software's XQuery add-on is cross-platform and works seamlessly on Mac OS X, Windows, and Linux. With XqUSEme, you can quickly and easily perform XQueries on single or multiple local or remote database XML files, or containers in BDBXML. Additionally, this tool allows you to query the document currently loaded in the current Firefox tab/window, regardless of how poorly formed the HTML may be. This is because the extension uses Firefox to try and convert the HTML into a well-formed document (though it is not guaranteed to validate).
Overall, XqUSEme is an efficient, reliable, and user-friendly extension for XQuery users that opens up countless possibilities for querying and analyzing XML files. It is a must-have tool for any developer or researcher who needs fast and effective access to XML data.
