Method and system for transforming an XML document to at least one XML document structured according to a subset of a set of XML grammar rules

A system for transforming an XML document for transforming an XML document structured according to a set of XML grammar rules into at least one XML document structured according to at least one subset of the set of XML grammar rules, the system comprising:

• a controller capable of executing a set of programmable instructions for retrieving at least one grammar restriction system sheet (GRSS) corresponding to at least one subset of a set of XML grammar rules, where the at least one GRSS includes transformation rules for transforming an XML document to at least one XML document structured according to the at least one subset of the set of XML grammar rules;
• and
• a transformation engine for using the transformation rules of each retrieved GRSS for transforming data elements of the XML document to data elements structured according to the at least one subset of the set of XML grammar rules to transform the XML document to the at least one XML document structured according to the at least one subset of the set of XML grammar rules.

A grammar restrictor for transforming a document structured according to a set of grammar rules into at least one document structured according to at least one subset of the set of grammar rules, the grammar restrictor comprising:

• a software module for retrieving at least one grammar restriction style sheet corresponding to the at least one subset of the set of grammar rules, where the at least one style sheet includes transformation rules for transforming the document to the at least one document structured according to the at least one subset of the set of grammar rules;
• and
• a software module for providing the retrieved at least one style sheet to a transformation engine for transforming data elements of the document using the transformation rules of the at least one retrieved style sheet to data elements structured according to the at least one subset of the set of grammar rules to transform the document to the at least one document structured according to the at least one subset of the set of grammar rules.
