in thread how to update an xml file by read data from csv file

Thanks bitingduck (Pilgrim). Your suggested solution is very clear and neat way of producing xml format file. But only problem is that i don't want to display last 2 closing container tags. I did try removing that from wrapper but it didn't work. Is ther any way we can't avoid writing the last 2 container tags please..

Error we get if we remove the closing tag :
mismatched tag at line 7, column 4, byte 333 at C:/Perl64/lib/XML/Pars +er.pm line 187.
Main program :
