The continuous growth in XML information repositories has been matched by increasing efforts in the development of XML retrieval systems. The main difference between XML retrieval and traditional information retrieval is that document components (so-called XML elements) instead of complete documents in response to a user query are returned in order to implement a more focused retrieval strategy. This focused retrieval approach is of particular benefit for information repositories containing long documents, or documents covering a wide variety of topics (e.g. books, user manuals and legal documents), where users' effort to locate relevant content can be reduced by directing them to the most relevant parts of these documents.
