Class FnDeepEqual

java.lang.Object
  org.ucl.xpath.function.Function
      org.ucl.xpath.function.FnDeepEqual

public class FnDeepEqual

extends Function

The function assesses whether two sequences are deep-equal to each other. To be deep-equal, they must contain items that are pairwise deep-equal; and for two items to be deep-equal, they must either by atomic values that compare equal, or nodes of the same kind, with the same name, whose children are deep-equal. This is defined in more detail below. The $collation argument identifies a collation which is used at all levels of recursion when strings are compared (but not when names are compared), according to the rules in 7.3.1 Collations in the specification.
