Summary:This paper introduces AxPRE summaries, a formalism that allows exploring the (semi-)structure of large XML collections. AxPRE summaries are implemented in a tool, DescribeX, that supports visualizing XML collections via summaries that can be interactively refined using a powerful and descriptive axis path regular expression language. Experimental results on gigabyte collections have shown that this flexibility does not come at the expense of efficiency.
