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-setp2
- The second node-set- Returns:
- A node-set containing all nodes that are in both p1 and p2
- Throws:
XPathException
-
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-setp2
- The second node-set- Returns:
- A node-set containing all nodes that are in p1 and not in p2
- Throws:
XPathException
-
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-setp2
- 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)
- Throws:
XPathException
-
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- Throws:
XPathException
-
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,- Throws:
XPathException
-
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,- Throws:
XPathException
