XTCcmp, the XQuery Compiler of a native XML database system, extends Starburst's well-known Query Graph Model to serve as an internal representation and basis for query restructuring of XQuery expressions. Furthermore, XTCcmp is able to generate execution plans supporting a wide range of both well-known and newly developed variants of core XML processing algorithms and indexes. Our demo visualizes all rule-based transformation stages, i. e., simplification, algebraic rewriting, and plan generation. Furthermore, via an interface to the extensible rule configuration, it allows interaction with the query compiler to vary configuration parameters and to control the compilation outcome.
