Method and apparatus for efficient management of XML documents

摘要

A storage manager represents XML-compliant documents as a collection of objects in memory, allowing the storage manager to manipulate the document, or parts of the document, with a consistent interface and to provide for features that are not available in conventional XML documents, such as element attributes with types other than text and documents that contain binary rather than text information. The XML-compliant document may be associated with a schema document which defines the arrangement of the document elements and attributes. The schema data associated with a document can contain a mapping between document elements and program code to be associated with each element. The storage manager further has methods for retrieving the code from the element tag. The retrieved code can then be invoked using attributes and content from the associated element and the element then acts like a conventional object.
