Partial update of server side XML documents
I am working on a specification for a service that offers CRUD operations on XML documents that conform to a standard schema. We have C, R and D under control and are looking for an good standards-based solution for supporting partial updates for XML documents already in the server. I would like to define the schema for an UpdateRequest which identifies a server resident XML document by its unique id and provides an XML element (lets call it UpdateInfo) that encapsulates how the server resident object should be updated. The content of the UpdateInfo element should specify how to partially update the desired XML document while leaving the rest of it unchanged. I am unfamiliar with XQuery but I suspect that it may be allow me to embed an XQuery statement within the UpdateInfo element to specify how to partially update the target XML document. The server would fetch the XML document by its id and then process it using the XQuery to modify it before storing it back. Another option might be to use simpler XPath/XSLT expressions to do the same. Does any one have any experience or advice on how best to do this. BTW, the specification I am working on is OASIS ebXML RegRep 4.0. TIA for your help. -- Regards, Farrukh Najmi Web: http://www.wellfleetsoftware.com
