net.sf.saxon.xpath.XPathEvaluator.evaluateSingle()

Prepare and execute an XPath expression, supplied as a string, and 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). @param expression The XPath expression to be evaluated, supplied as a string. @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 @deprecated since Saxon 8.9 - use the methods defined in the JAXP interface
