Eliminating dead-code from XQuery programs

One of the challenges in web software development is to help achieving a good level of quality in terms of code size and runtime performance, for increasingly popular domain specific languages such as XQuery. We present an IDE equipped with static analysis features for assisting the programmer. These features are capable of identifying and eliminating dead code automatically. The tool is based on newly developed formal programming language verification techniques [4, 3], which are now mature enough to be introduced in the process of software development.
