TypEx : a type based approach to XML stream querying [PDF]

open access: yes, 2003
We consider the topic of query evaluation over semistructured information streams, and XML data streams in particular. Streaming evaluation methods are necessarily eventdriven, which is in tension with high-level query models; in general, the more ...

An Inflationary Fixed Point Operator in XQuery

open access: yes, 2007
We introduce a controlled form of recursion in XQuery, inflationary fixed points, familiar in the context of relational databases. This imposes restrictions on the expressible types of recursion, but we show that inflationary fixed points nevertheless ...
