Method Detail

difference

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

distinct

public static NodeEnumeration distinct(Context c, NodeEnumeration in)
Given a node-set, return a subset that includes only nodes with distinct string-values

hasSameNode

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

intersection

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

leading

public static NodeSetValue leading(Context c, NodeEnumeration ns1, NodeEnumeration ns2)
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)
Find all the nodes in ns1 that are after the first node in ns2. Return empty set if ns2 is empty,
