 * The XPathAPI class provides methods to evaluate XPath expressions and select nodes or node lists from an XML document.
 * It uses the javax.xml.xpath.XPath and javax.xml.xpath.XPathFactory classes to create and evaluate XPath expressions.

 * <pre>
 * {@code
 * XPathAPI xPathAPI = new XPathAPI();
