Abstract

A computerized system that implements a type system can process one or more XML documents that comprise unknown schema elements, which may not correlate within one or more types in the type system. In one implementation, for example, a computer system receives one or more XML document feeds and deserializes only those schema elements that correlate with one or more system types. The computer system further passes the unknown schema elements to a buffer. An application program, such as an XML reader, can extract the unknown schema elements from the buffer as appropriate. In one implementation, for example, the application program maintains its own types separately from the system types. The application program can then correlate its application-specific types with the buffered schema elements to deserialize and process the buffered schema elements.

Claims19

Dependent claims

A method of processing a serialized XML document that includes typed schema elements and non-typed schema elements, the method performed at a client computer system comprising one or more computer processors, wherein the client computer system employs a type system having one or more types, the method comprising:

receiving one or more serialized XML documents over a network;
identifying one or more known schema elements of the one or more XML documents, wherein the one or more known schema elements correlate to one or more known system types at the client computer system;
identifying one or more unknown schema elements of the one or more XML documents, wherein the one or more unknown schema elements do not correlate to any of the one or more known system types;
providing a deserialized form of the one or more known schema elements to an application program;
storing the one or more unknown schema elements in an unknown element buffer data structure, wherein the one or more unknown schema elements are recorded in the serialized format received over the network, wherein the unknown element buffer data structure is separate and distinct from the received one or more serialized XML documents and wherein the unknown element buffer data structure comprises no known schema elements of the one or more XML documents which correlate to one or more known system types at the client computer system;
and
providing the application program with the at least one of the one or more buffered schema elements as one or more raw XML nodes.

4 more elements

A method of an application program processing a serialized XML feed that includes non-typed schema elements of one or more XML documents, the method performed in a computer system in which the computer system employs a type system having one or more types, the method comprising:

receiving one or more deserialized schema elements of one or more XML documents via one or more XML feeds, wherein the one or more deserialized schema elements correspond to a system type in the computer's type system;
identifying within a buffer the presence of one or more unknown schema elements of the one or more XML documents, wherein the one or more unknown schema elements do not correspond to any type in the type system, wherein the one or more unknown schema elements are stored within the buffer in a serialized format corresponding to the XML feed, wherein the buffer is separate and distinct from the received one or more XML documents, and wherein the buffer comprises no schema elements of the one or more XML documents which correspond to a system type in the computer's type system;
the application program correlating one or more of the unknown schema elements with one or more application-specific types that are maintained by the application program;
and
extracting from the buffer at least one of the one or more unknown schema elements using at least one of the one or more application-specific types maintained by the application program, wherein extracting from the buffer comprises extracting the at least one of the one or more unknown schema elements from the buffer as a raw XML node.
