## Abstract

We introduce a probabilistic modal logic $\pxml$ for probabilistic XML documents with applications to updates. We prove that this logic has the finite model property and that the validity problem can be solved in {\bf EXPSPACE}. The paper contains a number of worked examples. 18-23 June 2007
