Definition

XML Stream Processing refers to a family of data stream processing problems that deal with XML data. These include XML stream filtering, transformation, and query answering problems.

A main distinguishing criterion for XML stream processing techniques is whether to filter or transform streams. In the former scenario, XML streams are usually thought of as consisting of a sequence of rather small XML documents (e.g., news items), and the (Boolean) queries decide for each item to either select or drop it. In the latter scenario, the input stream is transformed into a possibly quite different output stream, often using an expressive transformation language.

Historical Background

With the spread of the XML data exchange format in the late 1990s, the research community has become interested in processing streams of XML data. The selective dissemination of information that is not strictly tuple-based, such as electronically disseminated news, was one of the first, and remains one...
