Abstract
The widespread acceptance of xml for exchanging tree-like data between
software tools has resulted in a growing interest in tools for binding
xml to native data structures of a language and the design of
dedicated languages for processing xml.
In the Stratego/XT project the components of transformation system
operate on term representations of programs. These representations are
encoded in the aterm format, which has a more explicit structure than
xml. Most of these components are implemented in Stratego, a
transformation language that supports a separation of rewrite rules
and rewriting strategies.
We have developed a set of tools that unifies xml processing and term
rewriting. The different needs of xml processing application are
served by providing several levels of term representations of xml. The
tool kit consists of syntax, document and data-oriented
representations of xml and the tools for manipulating them. In modular
and reusable tools we apply the basic principles of tree and hedge
grammars to obtain a natural, more explicitly structured
representation of an xml document in a term.
Our tools enable interoperability of xml and aterm tools. All term
representations of xml can be transformed using Stratego. This enables
the implementation of complex xml transformations using the strategic
rewriting paradigm and the generic traversals of Stratego.
