WebLogic Server 6.0sp2 API Reference

weblogic.apache.xalan.xpath
Interface XPathProcessor

All Known Implementing Classes:

XPathProcessorImpl

public interface XPathProcessor

An object that implements the XPathProcessor interface responsibilities include initializing the XPath expression from an XPath string. This should really be named XPathParser, and may be renamed in the future.

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.
