Abstract
A method for automatically generating semantically valid XPath expressions in a computer system is provided. The method includes populating an instance of a sequence-type model by organizing XML data into a hierarchical structure consistent with the sequence-type model. The method also includes priming the instance of the sequence-type model to remove ambiguities and redundancies, while retaining semantic validity of the instance of the sequence-type model. The method further includes scanning the instance of the sequence-type model to identify one or more location paths that match a search pattern, where an initial scan originates at a root of the hierarchical structure and subsequent scans originate from a termination point of a prior scan to incrementally search for location steps by searching along XPath axes. The method additionally includes determining whether a sequence type at each location step matches the search pattern and outputting a result as semantically valid XPath expression output.
