Abstract
The growing use of XML in commercial as well as non‐commercial domains to \u000Atransport information poses new challenges to concepts to access this \u000Ainformation. Common ways to access parts of a document use XPath‐expressions. \u000AWe provide a transformation of DTDs into a knowledge base in Description Logic. \u000AWe use reasoning capabilities grounded in description logics to decide if a \u000Agiven XPath can be satisfied by a document, and to guide the search of \u000AXML‐Processors into possibly successful branches of the document, thus avoiding \u000Aparts of the document that will not yield results. The extension towards object \u000Aoriented subclassing schemes opens this approach towards OODB‐queries. In \u000Acontrast to other approaches we do not use any kind of graph representing the \u000Adocument structure, and no steps towards incorporation of the \u000AXML/OODB‐processor itself will be taken.
