XSLUtil() Prevents instanciation.

Method Summary

static boolean	equals(ExpressionContext context, NodeIterator ni1, NodeIterator ni2) Checks ni1 and ni2 for strict equality (same names, same attributes, same child nodes...).
static boolean	equals(ExpressionContext context, Node n1, Node n2) Checks n1 and n2 for strict equality (same names, same attributes, same child nodes...).
static String	evaluate(ExpressionContext context, String avt) Returns an interpreted value (AVT) of a Node attribute whose name is equals to the avt parameter.
static String	evaluate(XSLProcessorContext context, ElemExtensionCall elem) Returns an interpreted value (AVT) of a Node attribute whose name is "avt".
