GNU Xmlat is derived from GNU SXML which used to be a tool to define and implement at same time a markup language.
Given a document containing user defined tags and their definition a new document is produced.
The new document is generated replacing the tags with their definition (it is possible to associate functions to tags).
Xmlat aims to be the new XML tools for GNU operating system. Besides the old feature of GNU SXML, it will contains more new features for convenient XML processing, and provides conversion between XML and other format like json/YAML etc.
