1. Method for the fast searching of elements in binary representations of structured XML-based documents wherein a textual path (AbsP, TeilP) for indexing elements and/or attributes is encoded in such a way that the data types which are instanced in the path and which are derived through polymorphism are uniquely replaced by standardized data types, each standardized data type being specified in a manner whereby, proceeding from the basic data type of the respective data type, a data type is searched which contains the element or attribute following in the path and which can be uniquely determined with reference to its derivation from the basic type, and wherein the encoded textual path is then uniquely recognized by its bit pattern and the searched elements and/or attributes are located with this in the encoded, XML-based document.
