Examples of AxisIterator

client.net.sf.saxon.ce.tree.iter.AxisIterator
A SequenceIterator is used to iterate over a sequence. An AxisIterator is a SequenceIterator that throws no exceptions, and that always returns nodes. The nodes should all be in the same document (though there are some cases, such as PrependIterator, where this is the responsibility of the user of the class and is not enforced.)
net.sf.saxon.om.AxisIterator
A SequenceIterator is used to iterate over a sequence. An AxisIterator is a SequenceIterator that throws no exceptions. Despite its name, an AxisIterator is not invariably used to find nodes on an axis of a tree, though this is its most common use. For example, the class ArrayIterator is also defined as an AxisIterator.
