Working version of XML parser from configuration file path

Added some changes in the "getRootElement" and new "layoutlist.xml" is added for "unit-test" module.
XML parser works perfectly in the installation,only the failure of "unit-test" is left to be solved.
Some refactoring related to "layoutlist.xml" will be updated soon.
