FLOPER is the "Fuzzy LOgic Programming Environment for Research" designed in our research group for assisting the development of real-world applications where fuzzy logic might play an important role. This is the case of our recently proposed extension for the popular xpath query language in order to handle flexible queries which provide ranked answers, fuzzy variants of operators and, or and avg for xpath conditions, as well as two structural constraints, called down and deep, for which a certain degree of relevance can be associated.

In this paper we present a fuzzy variant of the xpath query language for the flexible information retrieval on XML documents. Our main purpose is to provide a repertoire of operators that offer the possibility of managing satisfaction degrees by adding structural constraints and fuzzy operators inside conditions, in order to produce a ranked sorted list of answers according to user's preferences when composing queries. By using the FLOPER system designed in our research group, our proposal has been implemented with a fuzzy logic language to take profit of the clear synergies between both target and source fuzzy languages.
