org.apache.xpath.patterns.NodeTest
org.apache.xpath.axes.PredicatedNodeTest
org.apache.xpath.axes.LocPathIterator
org.apache.xpath.axes.MatchPatternIterator
This class treats a LocationPath as a filtered iteration over the tree, evaluating each node in a super axis traversal against the LocationPath interpreted as a match pattern. This class is useful to find nodes in document order that are complex paths whose steps probably criss-cross each other.

acceptNode(int n,

Test whether a specified node is visible in the logical view of a TreeWalker or NodeIterator. |
void |
detach()
Detaches the iterator from the set which it iterated over, releasing any computational resources and placing the iterator in the INVALID state. |
int |
nextNode()
Returns the next node in the set and advances the position of the iterator in the set. |
void |
setRoot(int context,
java.lang.Object environment)
Initialize the context values for this expression after it is cloned. |
