Abstract
We present a novel, yet simple, technique for the specification of context in structured documents that we call caterpillar expressions. Although we are applying this technique in the specification of context-dependent style sheets for HTML, XML, and SGML documents, it is clear that it can be used in other environments such as query specification for structured documents and for computer program transformations. In addition, we present a number of theoretical results that allow us to compare the expressive power of caterpillar expressions to that of tree automata.
