Transmorpher is an environment for defining and processing complex transformation flows. It is partly based on the transformation language XSLT recommended by the "World-wide web consortium" (W3C). XSLT is overly complex for simple transformations (such as renaming tags) and too simple for composing transformations (such as applying a transformation until it does not apply anymore). It enables the description of individual transformations but does not support transformation combination and complex data flows.
Transmorpher takes as input a transformation flow described in XML. It is portable, open to other transformation engines and yet sufficient for expressing complex flows of transformations.

Transmorpher is an environment for processing generic transformations on XML documents. It aims at complementing XSLT in order to:

describe easily simple transformations (removing elements, replacing tag and attribute names, concatenating documents...);
allowing regular expression transformations on the content;
composing transformations by linking their (multiple) output to input;
iterating transformations, sometimes until saturation (closure operation);
integrating external transformations.

Transmorpher is a first Java implementation of these concepts, taking advantage of existing XML parsers and XSLT processors.
