摘要

The method of coding a structured document comprises: - a step of obtaining at least one pattern designated as "primary" representing at least one of the pieces of structural information of data of said document, - a step (200 to 230) of obtaining a part of the document different from the entirety of the document, - a step of creating at least one derived pattern formed by modifying a primary pattern, representing data of said part of the document and - a step of coding data of the document to provide a code, said code associating a pattern with at least one piece of coded data. In embodiments, during the coding step, a step is carried out of determining a pattern that best describes data to code, the pattern associated with said data being that closest pattern.
