Fix scripting module compatibility with XMLBeans 5.3.0

- Update JSOMElementConvertor to handle XMLBeans 5.3.0 API changes
- Add fallback mechanisms for getXmlObject() method removal
- Implement string-based XML parsing as ultimate fallback
- Normalize XML whitespace to fix test assertions
- Maintain backward compatibility with older XMLBeans versions
