In this paper we present an extension of the XPath query language for the handling of flexible queries. In order to provide ranked answers, our approach proposes fuzzy variants of and, or and avg operators for XPath conditions, as well as two structural constraints, called down and deep, for which a certain degree of relevance is associated. Our proposal has been implemented with a fuzzy logic language to take profit of the clear sinergies between both target and source fuzzy languages.
