【 摘 要 】

We address a problem of updating XML documents having their XML schema described by a Document Type Definition (DTD) without breaking their validity. We present a way how to express constructs available in DTD in a functional data model and propose algorithms for performing insert, update and delete operations. After that we embed the update capability into an existing query language for XML. This paper thus outlines the whole "life cycle" of the approach from the problem analysis to its implementation.
