/**
 * {@link XpathTransformer} is a class that transforms HTML content into XML format based on XPath expressions.
 * It extracts data from an HTML document by applying XPath rules defined in {@link #fieldRuleMap}.
 * The extracted data is then formatted into an XML structure and stored in the {@link ResultData}.
 * <p>

 * </p>
 *
 * <p>
 * The transform method takes a ResponseData object containing the XML content and returns a ResultData object with the extracted and formatted data.
 * </p>
 *
 * <p>
 * The getData method returns the data extracted from AccessResultData. It can return either a String representation of the XML or a Map/Bean representation based on the configured dataClass.
 * </p>
 *
 * <p>
 * Example Usage:
