org.pdf4j.saxon.sxpath.XPathExpression
This class is a representation of an XPath Expression for use with the {@link XPathEvaluator} class.It is modelled on the XPath API defined in JAXP 1.3, but is cut down to remove any dependencies on JAXP 1.3, making it suitable for use on vanilla JDK 1.4 installations. @author Michael H. Kay
