Querying JSON and XML : Performance evaluation of querying tools for offline-enabled web applications
This article explores the viability of third-party JSON tools as an alternative to XML when an application requires querying and filtering of data, as well as how the application deviates between browsers. We examine and describe the querying alternatives as well as the technologies we worked with and used in the application. The application is built using HTML 5 features such as local storage and canvas, and is benchmarked in Internet Explorer, Chrome and Firefox. The application built is an animated infographical display that uses querying functions in JSON and XML to filter values from a dataset and then display them through the HTML5 canvas technology. The results were in favor of JSON and suggested that using third-party tools did not impact performance compared to native XML functions. In addition, the usage of JSON enabled easier development and cross-browser compatibility. Further research is proposed to examine document-based data filtering as well as investigating why performance deviated between toolsets.
