The present invention provides a method and system for performing operations on data using XML streams. An XML schema defines a limited set of operations that may be performed on data. These operations include addition, subtraction, multiplication and division. The operations are placed in an XML stream that conforms to the XML schema. The XML stream may perform one or more of the defined operations on the data. The limited set of operations allows data to be validated and processed without excessive overhead.
