Examples of org.apache.xpath.XPath.execute()

org.apache.xpath.XPath.execute()
Given an expression and a context, evaluate the XPath and return the result. @param xctxt The execution context. @param contextNode The node that "." expresses. @param namespaceContext The context in which namespaces in theXPath are supposed to be expanded. @return The result of the XPath or null if callbacks are used. @throws TransformerException thrown ifthe error condition is severe enough to halt processing. @throws javax.xml.transform.TransformerException
