1. A method for searching of elements in binary representations of structured XML-based documents, comprising the steps of:
- encoding a textual path for indexing elements or attributes, wherein the path comprises data types;
replacing at least one of the data types, that are instanced in the path and which are derived through polymorphism, with standardized data types, wherein the respective standardized data type is obtained byderiving a basic data type of the respective data type, andsearching a data type to establish that the searched data type contains the element or attribute following in the path and that is uniquely determined with reference to its derivation from the basic data type;
providing a unique identification for the textual path using a bit pattern after encoding, wherein the bit pattern includes the searched elements or attributes.

Abstract
A method serves to encode textual paths for indexing and querying structured, for example, XML-based documents and serves to execute and improved filtering of binarily represented XML documents. A development of the method results in all indices being identical even in the event that a polymorphism is inserted therein. When storing these textual paths for indexing or querying, only one smaller volume of data has to be stored or transmitted. A comparison of this data can also subsequently ensure more rapidly during a query since the volume of data to be compared is smaller.

6. A method for filtering fragments in binary presentations of structured XML-based documents, comprising the steps of:
-
encoding a context path for indexing elements or attributes wherein the path comprises data types; replacing at least one of the data types that are instanced in the path and which are derived through polymorphism with standardized data types, wherein the respective standardized data type is obtained by deriving a basic data type of the respective data type, and searching a data type to establish that the searched data type contains the element or attribute following in the path and that is uniquely determined with reference to its derivation from the basic data type; providing a unique identification for the context path using a bit pattern after encoding, wherein the bit pattern includes the searched elements or attributes.
