net.sf.saxon.xpath.XPathExpression.evaluateSingle()
Execute a prepared XPath expression, returning the first item in the result. This is useful where it is known that the expression will only return a singleton value (for example, a single node, or a boolean). @return The first item in the sequence returned by the expression. If the expressionreturns an empty sequence, this method returns null. Otherwise, it returns the first item in the result sequence, represented as a Java object using the same mapping as for the evaluate() method

                    findSpeaker.setContextNode(line);


                    // Output the name of the speaker and the content of the line
                    System.out.println(findSpeaker.evaluateSingle() + ":  " + line.getStringValue());
                }


                // If no lines were found, say so
                if (!found) {
                    System.err.println("No lines were found containing the word '" + word + "'");
