The recent success of XML as a standard to represent semi-structured data, and the increasing amount of available XML data, pose new challenges to the data mining community. In this paper we present the X MINE operator a tool we developed to extract XML association rules for XML documents. The operator; that is based on XPath and inspired by the syntax of XQuery, allows us to express complex mining tasks, compactly and intuitively. X MINE can be used to specify indifferently (and simultaneously) mining tasks both on the content and on the structure of the data, since the distinction in XML is slight.
