Class SimpleXPathEvaluator

  • public class SimpleXPathEvaluator
extends java.lang.Object
    This class is used for parsing the configuration parameters of the XML Parser2. After it compiles everything needed into an array it is used for matching elements found in the XML being parsed. Also this class keeps track of the elements that the XML Parser2 have entered in. Since XML Parser2 could be in only one mode (Input or Output) the THIS CLASS IS FOR INTERNAL USAGE ONLY! MAY CHANGE IN THE FUTURE!
    Since:
    7.0
