intersection


public static NodeEnumeration intersection(Context c,
                                           NodeEnumeration p1,
                                           NodeEnumeration p2)
                                    throws XPathException

Return the intersection of two node-sets

Parameters:: p1 - The first node-set; p2 - The second node-set
Returns:: A node-set containing all nodes that are in both p1 and p2

difference


public static NodeEnumeration difference(Context c,
                                         NodeEnumeration p1,
                                         NodeEnumeration p2)
                                  throws XPathException

Return the difference of two node-sets

Parameters:: p1 - The first node-set; p2 - The second node-set
Returns:: A node-set containing all nodes that are in p1 and not in p2

hasSameNode


public static boolean hasSameNode(Context c,
                                  NodeEnumeration p1,
                                  NodeEnumeration p2)
                           throws XPathException

Determine whether two node-sets contain at least one node in common

Parameters:: p1 - The first node-set; p2 - The second node-set
Returns:: true if p1 and p2 contain at least one node in common (i.e. if the intersection is not empty)

distinct


public static NodeEnumeration distinct(Context c,
                                       NodeEnumeration in)
                                throws XPathException

Given a node-set, return a subset that includes only nodes with distinct string-values

leading


public static NodeSetValue leading(Context c,
                                   NodeEnumeration ns1,
                                   NodeEnumeration ns2)
                            throws XPathException

Find all the nodes in ns1 that are before the first node in ns2. Return empty set if ns2 is empty,

trailing


public static NodeSetValue trailing(Context c,
                                    NodeEnumeration ns1,
                                    NodeEnumeration ns2)
                             throws XPathException

Find all the nodes in ns1 that are after the first node in ns2. Return empty set if ns2 is empty,
