EXTENDABLE AND PLUGGABLE METHOD FOR VALIDATING XML DATA

A method of validating XML data comprises (a) registering a plurality of validators that are each responsible for validating a certain XML set of rules, (b) creating common XML data structures to be shared between the validators, (c) invoking registered validators and granting access to common XML data structures, and (d) reporting validation results for each of the validators. Two or more validators having similar pattern validation structures may share the common XML data structure of a data builder. Furthermore, the validators may be invoked in the order in which they are registered in step (a) and granted access to the common XML data structures that are built in step (b). In addition, the step of reporting the validation results may include formatting the validation results as error messages generated by each validator and outputting the error messages via an outputter.
