Class %XML.XPATH.Utils.TreeBuilder

class %XML.XPATH.Utils.TreeBuilder extends %XML.XPATH.ResultHandler

This class stores the results of evaluation of an XPATH expression in ^CacheTemp(Tree,MatchKey) The Tree is a unique integer value, the MatchKey is an integer key which varies from 1 .. n. For each match of the xpath expression, the results are stored in the appropriate subtree of ^CacheTemp. The match results can be of two forms, values and DOMS. If the XPATH expression matches an element, a DOM is returned which represents the matching element and it's childeren. If the XPATH expression matches a value then just the value is returned.
