Abstract:
1. A method for improving functionality of a binary representation of an XML-based content description, wherein a structure of any instance of an Extensible Markup Language (XML) document corresponds to a tree-like data structure, the method comprising the steps of: providing that each tree node represents an element of the content description and has a structure defined in a schema; providing the tree nodes in the binary representation with tree branch codes; providing that the respective tree branch code has a schema branch code and, when there are multiple occurrences of an associated child node based on the definition of the schema, a position code; forming a first table for the schema branch codes when each node is being coded, wherein the first table contains only complex elements containing child elements, and a path termination code whose data structure permits a branch to child nodes; forming a second table for the schema branch codes when each node is being coded, wherein the second table contains the complex elements as well as attributes and simple elements which represent leaves of the tree-like data structure, and wherein said attributes and simple elements do not contain child elements; and forming a complete path by chaining together tree nodes in the binary representation such that, except for a last node in the complete path, only the tree nodes in the first table are referenced, the last tree node is taken from the second table, and a penultimate node of the complete path contains a path termination code.
