Examples of net.sf.saxon.om.NodeInfo.iterateAxis()

net.sf.saxon.om.NodeInfo.iterateAxis()
Return an iteration over all the nodes reached by the given axis from this node @exception UnsupportedOperationException if the namespace axis isrequested and this axis is not supported for this implementation. @param axisNumber an integer identifying the axis; one of the constantsdefined in class {@link net.sf.saxon.om.Axis} @return an AxisIterator that delivers the nodes reached by the axis inturn. The nodes are returned in axis order (document order for a forwards axis, reverse document order for a reverse axis). @see net.sf.saxon.om.Axis @since 8.4
