public class RootWalkerMultiStep
extends ChildWalkerMultiStep

This class extends ChildWalkerMultiStep to handle the root step of patterns such as "/foo/baz" where the first step is the root, and the rest of the steps are simple child steps.

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.
