Validating an XML document

A computer program product comprising a non-transitory computer readable storage medium including a computer readable program code, where the computer readable program code when executed on a computer causes the computer to:

• parse at least one XML document to be validated and to represent XML data in the at least one XML document as data objects in at least one data object model in a memory;
• parse at least one rule document and represent rule data parsed from the at least one rule document as scoped rule objects in a rule object model in the memory;
• extract part of the data objects from the at least one data object model and extract part of the scoped rule objects from the rule object model;
• and
• perform a partial validation in a corresponding execution context that supports a fail-fast implementation, of the extracted part of the data objects based upon a scope specified by the extracted part of the scoped rule objects.

A method comprising:

• receiving a schematron data set including information indicative of a plurality of rules, and with each given rule of the plurality of rules including:
• (i) rule logic data reflecting substance of the given rule, and (ii) rule context data reflecting a context in which the given rule is applicable;
• receiving an XML instance document including information indicative of a plurality of instantiated contexts;
• selecting a selected subset of rules of the plurality of rules with each rule of the selected subset of rules having the rule context data reflecting the context that matches one of the plurality of instantiated contexts of the XML instance document;
• sharing the selected subset of rules;
• and
• performing rule matching on the XML instance document using the selected subset of rules, comprising performing a partial validation that supports a fail-fast implementation of the XML instance document using the selected subset of rules.
