Optimized methods and devices for the analysis, processing and evaluation of expressions of the XPath type on data of the binary XML type

摘要

An object of the invention is in particular methods and devices for analyzing, processing and evaluating expressions of the XPath type on data of the XML type with which coding or decoding tables are associated. After generating a list comprising a set of targets from the XPath-type expression, one target is linked to the coding/decoding table (115). When one part of the set of data is accessed, a reference to an item is identified in the table using the part of data. It makes it possible to access a target linked to the table in order to reconstruct the item (145) and evaluate the expression (150). According to a particular embodiment, a parameter representing the discriminating character of the targets is determined and linked to the table to enable the discriminating character of the targets to be taken into account during the evaluation of the XPath expression on the XML-type data.
