This paper presents an advanced indexing structure for XML documents which allows the evaluation of loose constraints on both structure and content of XML documents. This structure is an extension of the one presented in [1], and allows an evaluation of flexible queries performed into two subsequent steps: content-based matching and structure-based matching (applied to documents pre-selected by the first evaluation phase)
