Abstract
The present invention provides a system and method for the efficient indexing and delivery of information to interested users who have expressed an interest in or 'subscribed' to information items that are continuously released or 'published' by some data source in XML format. Previously, publish and subscribe systems accepted keyword-based subscription profiles and did not support subscription to XML documents according to their structures. Direct approach to implement XML-based publish and subscribe system by checking each user profile against an XML document is very time consuming. The presentation invention, though, provides an efficient method to identify interested subscribers for each XML document by indexing queries utilizing a graphical structure of nodes. When an XML document is published, the index identifies all matched expressions in the index and delivers at least a portion of an XML document to a user who has expressed an interest in receiving this information.
