Abstract

A method for interfacing with an XML (Extensible Markup Language) parser generator to generate deserialization information interleaved with XML parsing and validation, including: providing an XML parser generator with information about the schema which the instance data conforms to; providing a data reporting application programming interface (API) and a generator module; providing one or more implementations of the data reporting API; providing the XML parser generator with a selected data reporting API implementation module; generating an XML parser to parse and validate instance documents conforming to the specified input schema and deserializing the instance documents into the desired deserialization format during the parse.

Claims

1. A method for interfacing with an XML (Extensible Markup Language) parser generator to generate deserialization information interleaved with XML parsing and validation, the method comprising:

providing an XML parser generator with information about the schema which the instance data conforms to;

providing a data reporting application programming interface (API) and a generator module;

providing one or more implementations of the data reporting API;

providing the XML parser generator with a selected data reporting API implementation module;

generating an XML parser to parse and validate instance documents conforming to the specified input schema and deserializing the instance documents into the desired deserialization form during the parse.

2. The method of claim 1, wherein the data reporting API is used to generate code that creates appropriate data structures to store the instance data, assign values to the data structures, and allocate space.

3. The method of claim 1, wherein the data reporting API is used to generate code that creates an event stream representation of the instance data.

4. The method of claim 1, wherein two types of information is exchanged between the data reporting API and the XML parser generator.

5. The method of claim 4, wherein a first type of information describes a current context that the XML parser generator is currently generating code for.

6. The method of claim 4, wherein a second type of information involves how the instance data is referenced during runtime and how the XML parser generator refers to the referenced instance data for parsing and validation requirements.

7. A computer program product for interfacing with an XML (Extensible Markup Language) parser generator to generate deserialization information interleaved with XML parsing and validation, the computer program product comprising:

a storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising;

providing an XML parser generator with information about the schema which the instance data conforms to;

providing a data reporting application programming interface (API) and a generator module;

providing one or more implementations of the data reporting API;

providing the XML parser generator with a selected data reporting API implementation module;

generating an XML parser to parse and validate instance documents conforming to the specified input schema and deserializing the instance documents into the desired deserialization form during the parse.

8. The computer program product of claim 7, wherein the data reporting API is used to generate code that creates appropriate data structures to store the instance data, assign values to the data structures, and allocate space.

9. The computer program product of claim 7, wherein the data reporting API is used to generate code that creates an event stream representation of the instance data.

10. The computer program product of claim 7, wherein two types of information is exchanged between the data reporting API and the XML parser generator.

11. The computer program product of claim 10, wherein a first type of information describes a current context that the XML parser generator is currently generating code for.

12. The computer program product of claim 10, wherein a second type of information involves how the instance data is referenced during runtime and how the XML parser generator refers to the referenced instance data for parsing and validation requirements.
