Fix Absolute Path to list with Integer/String key

 - Introduced normalizedXpath to normalize the xpath and cpspath
 - Introduced normalizedAncestorpath to normalize the ancestor path in xpath and cpspath
 - Added new condition in the ANTLR Grammar to capture the invalid path in the xpath
 - Introduced PathParsingException to replace the IllegalStateException
