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
