Class XPath

java.lang.Object

  +--weblogic.apache.xerces.validators.schema.identity.XPath

Direct Known Subclasses:

Field.XPath, Selector.XPath

public class XPath

extends java.lang.Object

Bare minimum XPath parser.

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.
