TALK REMINDER -- TODAY -- Syntax-directed Transformations of XML Streams
Date: Jan 3, 2005, 14:00 s.t.
Location: Seminarraum 184/2, Favoritenstrasse 9-11 3rd floor
Title: Syntax-directed Transformations of XML Streams (TransformX)
We discuss the TransformX framework for syntax-directed transformations of XML
streams. In this framework, we define stream transformations as a special form
of attributed extended regular tree grammars where all attributes may be
evaluated in a single pass over the input, a necessity in stream processing. In
the tradition of tools such as Yacc, the TransformX parser generator translates
attribute grammars to Java source code, which may then be compiled and
We motivate our approach in developing this tool, present the theoretical
foundations, and study the complexity of program generation. We further provide
details on our prototype implementation and first experimental results.
