public class AttributeWalkerOneStep
extends AxesWalker

This walker should be used when the walker is at the end of a location path, or is the only step. It has a much simplified nextNode() method.

This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.
