Sablotron Adapter -- XSL tranformations in Erlang

As you can guess, Sablotron adapter is an Erlang adapter for the C++ library Sablotron, that allows Erlang programs to perform efficient XSL transformations on XML documents both as files or Erlang binaries.

Motivation

When developing monet, a flexible monitoring tool for the VoDka project, we needed a way of generating monet output to different devices: standard browsers, text-only browsers, wap-enabled terminals, and so on. Generating monet output as XML documents and then transforming them using an XSL engine with rules to choose the appropriate XSL style became an elegant and effective solution.

How does it work?

• A sablotron adapter developed in C that uses the sablotron library.
• A generic server sablotron in charge of controlling the interaction between sablotron adapter and the rest of Erlang processes.
