cduce

programming language adapted to the manipulation of XML data

CDuce is a modern programming language adapted to the manipulation of XML documents. Some of CDuce's peculiar features: - XML objects can be manipulated as first-class citizen values: elements, sequences, tags, characters and strings, attribute sets; sequences of XML elements can be specified by regular expressions, which also apply to characters strings; - functions themselves are first-class values, they can be manipulated, stored in data structure, returned by a function,...; - a powerful pattern matching operation can perform complex extractions from sequences of XML elements; - a rich type algebra, with recursive types and arbitrary boolean combinations (union, intersection, complement) allows precise definitions of data structures and XML types; general purpose types and types constructors are taken seriously (products, extensible records, arbitrary precision integers with interval constraints, Unicode characters); - polymorphism through a natural notion of subtyping, and overloaded functions with dynamic dispatch; - an highly-effective type-driven compilation schema. CDuce is fast, functional, type-safe, and conforms to basic standards: Unicode, XML, DTD, Namespaces are fully supported, partial support of XML Schema validation is in alpha testing (and undocumented) while queries are being implemented.
