/**
 * Utility method to retrieve an XML element using an XPath expression. Note that this method is
 * namespace aware and will require you to use the "xp" prefix in your XPath queries. For example, an XPath query
 * for a Spring XML configuration will look like this :
 * /xp:beans/xp:bean[@id="FileListSync"]/xp:property[@name="syncUrl"]
 * Currently there is no way to rename the prefix.
 *
 * @param scopeElement    the scope in which to execute the XPath query
 * @param xPathExpression the XPath query to select the element we wish to retrieve. In the case where multiple
 *                        elements match, only the first one will be returned.
 * @return the first element that matches the XPath expression, or null if no element matches.
 * @throws JDOMException raised if there was a problem navigating the JDOM structure.
