Validity-Sensitive Querying of XML Databases

We consider the problem of querying XML documents which are not valid with respect to given DTDs. We propose a framework for measuring the invalidity of XML documents and compactly representing minimal repairing scenarios. Furthermore, we present a validity-sensitive method of querying XML documents, which extracts more information from invalid XML documents than does the standard query evaluation. Finally, we provide experimental results which validate our approach.
