There is provided a roller for a printing machine that includes a cylindrically shaped wall with at least partially one layer of a fiber braid and plastics material infiltrated in the fiber braid. The fin structure and the insulating structure are disposed on the substrate. The tear element joining the shaft to the capsule is placed in an entrance area at an angle in the free edge of the shaft. If no fast parser is available, the method includes parsing the instance by using a generic parser, and generating the fast parser for the structured document, in parallel.
