A method for improving functionality of a binary representation of an XML-based content description, wherein a structure of any instance of an XML document corresponds to a tree-like data structure is provided. The method includes providing that each tree node represents an element of the content description and has a structure which is 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, and re-sorting a complete path such that all the position codes are moved to an end of the respective complete path, thereby enabling simpler filtering of the binary representation.

Method for improving the functionality of a binary representation

A method for improving functionality of a binary representation of an XML-based content description, wherein a structure of any instance of an XML document corresponds to a tree-like data structure, is provided. The method includes providing that each tree node represents an element of the content description and has a structure which is 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 decoding, via a decoder within a telecommunications device, paths with new elements, which does not conform to a previous schema, by communicating to the decoder one of (a) the associated tree structure nodes beforehand, and (b) a completely new schema.

A method is provided for improving functionality of a binary representation of an XML-based content description, wherein a structure of any instance of an XML document corresponds to a tree-like data structure. The method includes 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 appropriate, a position code; forming first and second tables for the schema branch codes when each node is being coded, the first table including complex elements containing child elements and the second table including complex elements as well as attributes and simple elements which represent leaves of the tree-like data structure; and forming a complete path by chaining together tree nodes in the binary representation.
