Abstract

A computer-implemented method includes obtaining an XML document template object in which a subset of fields of the XML document is designated by placeholders. The XML document template object is prepared based on a prior instance of the XML document. The method further involves processing the subset of fields in an instance of the XML document that are designated by placeholders in XML document template object.

Claims

1. A computer-implemented method carried out by causing at least one processor to execute instructions recorded on a computer-readable storage medium, the computer-implemented method comprising:

obtaining an XML document template object in which a subset of fields of an XML document are designated by placeholders; and

processing the subset of fields in an instance of the XML document that are designated by placeholders in XML document template object,

wherein the XML document template object is prepared based on a prior instance of the XML document.

2. The computer-implemented method of claim 1, wherein the subset of fields of the XML document that are designated by placeholders contain information relevant as input or output data of an application function.

3. The computer-implemented method of claim 1, wherein obtaining an XML document template object in which the subset of fields are designated by placeholders includes preparing the XML document template object based on an instance of the XML document.

4. The computer-implemented method of claim 3, wherein preparing the XML document template object based on an instance of the XML document includes replacing particular elements, attributes and content fields in the instance of the XML document with placeholders.

5. The computer-implemented method of claim 1, wherein processing the subset of fields of the XML document that are designated by placeholders involves processing the XML document only for those fields for which placeholders are defined in the XML document template object.

6. The computer-implemented method of claim 1, wherein processing the subset of fields of the XML document that are designated by placeholders involves extracting information from the subset of fields in the XML document using the XML document template object as reference.

7. The computer-implemented method of claim 6, wherein extracting information from the subset of fields in the XML document using the template object as reference involves parsing the XML document which returns a context object having a dictionary of key-value pairs with the placeholders as keys.

8. The computer-implemented method of claim 1, wherein processing the subset of fields of the XML document that are designated by placeholders involves rendering an XML document by inserting information in the fields associated with the placeholders defined in the XML document template.

9. The computer-implemented method of claim 8, wherein the inserted information is generated at runtime.

10. The computer-implemented method of claim 8, wherein the inserted information is derived from a context object having a dictionary of key-value pairs with the placeholders as keys.

11. A computer program product embodied in non-transitory computer-readable media carrying executable code, the computer program product comprising:

code which when executed,

obtains an XML document template object in which a subset of fields of an XML document are designated by placeholders; and

processes the subset of fields in the XML document that are designated by placeholders in XML document template object,

wherein the XML document template object is prepared based on a prior instance of the XML document.

12. The computer program product of claim 11, wherein the code when executed:

prepares the XML document template object based on an instance of the XML document.

13. The computer program product of claim 12, wherein the code when executed:

replaces particular elements, attributes and content fields in the instance of the XML document with placeholders.

14. The computer program product of claim 11, wherein the code when executed:

processes the XML document only for those fields for which placeholders are defined in the XML document template object.

15. The computer program product of claim 11, wherein the code when executed:

extracts information from the subset of fields in the XML document using the XML document template object as reference.

16. The computer program product of claim 11, wherein the code when executed:

parses the XML document to return a context object having a dictionary of key-value pairs with the placeholders as keys.

17. The computer program product of claim 11, wherein the code when executed:

renders an instance of XML document by inserting information in the subset of fields associated with the placeholders defined in the XML document template.

18. A computer-based system implemented by instructions recorded on a non-transitory computer readable storage medium and executable by at least one processor, the computer-based system comprising:

a processor; and

a computer readable storage medium;

wherein the computer readable storage medium carries an XML document template object in which a subset of fields of an XML document are designated by placeholders; and

wherein the processor is configured to process an instance of the XML document with reference to the XML document template object.

19. The computer-based system of claim 18, wherein the processor is configured to extract information from the subset of fields in the instance of the XML document that are designated by placeholders in the XML document template object.

20. The computer-based system of claim 18, wherein the processor is configured to render an instance of the XML document by inserting information in the subset of fields that are designated by placeholders in the XML document template object.
