/**
 * Executes an XPath expression on some XML text or JavaBean
 * This function always returns lists. If the xpath expression matches only a single values it will return it as single element in a list. If you only want to retrieve single values use xpath().
 * The given object to parse as XML is either a dom4j branch object (mostly document or element), a String containing XML text or a JavaBean. In the last case this function uses JXPath functionality to find a bean property value.
 * This uses the Apache library JXPath under the hood. See their documentation for details how XPath is used to browser JavaBeans.
 * @param object Object to inspect/*  w  w w .  j av  a  2  s. c o  m*/
 * @param xpath XPath expression
 * @param ns Map of namespace prefix declarations used in the XPath. Keys are prefixes, values are namespace URIs.
 * @return Returned value
