Performs a parse by iterating through a List of preferred Parser s until a successful parse is performed and a Parse object is returned. If the parse is unsuccessful, a message is logged to the WARNING level, and an empty parse is returned.

 public ParseResult parseByExtensionId(String extId,
    Content content) throws ParseException

            " of type " + content.getContentType());
      }  
      return null;
    }
}

Method parses a Content object using the Parser specified by the parameter extId, i.e., the Parser's extension ID. If a suitable Parser is not found, then a WARNING level message is logged, and a ParseException is thrown. If the parse is uncessful for any other reason, then a WARNING level message is logged, and a ParseStatus.getEmptyParse() is returned.
