Abstract:
1. A computer-implemented method comprising the steps of: (1) during evaluation of at least a first XPath expression comprising a plurality of steps, an XPath evaluation component identifying a next unmatched step in the plurality of steps; (2) the XPath evaluation component sending an event request to an XML event-streaming component; (3) in response to the event request, the XML event-streaming component streaming an XML event to the XPath evaluation component; (4) the XPath evaluation component matching the XML event to said next unmatched step; (5) repeating steps 1-4 with respect to at least a new next unmatched step in the first XPath expression, until the XPath evaluation component determines that there are no remaining unmatched steps in the first XPath expression; and (6) outputting an XPath result based at least upon the XML event streamed in the last iteration of step 3; wherein the method is performed by one or more computing devices.
