AXIL: An XPath Intermediate Language

XPath is a central component of many XML-processing languages; therefore, it is important to process XPath queries efficiently. We describe AXIL, a functional intermediate language, which allows us to simplify the task of optimising and compiling XPath for efficient execution. We describe interesting parts of the syntax and semantics of AXIL and particular design issues which shaped this language, sketch the translation from XPath into AXIL, and discuss our experience with using AXIL for an optimising XPath compiler backend.
