    really thanks

      Your inconsistent indention makes it very hard to read, but it seems that's still not the entire script. At least there are unclosed curly braces.

      You don't seem to keep references to Spreadsheet::ParseExcel objects, so unless your version of that module is very old, no memory should leak from here.

      One thing I do notice is that $materialmapping_table_xml will continually grow, and there's not much you can do about it, except moving to a solution that writes each $materialmapping_item to a file, and then stops keeping it in memory.

        my spreadsheet::parseexcel version is 0.59 and perl version is 5.10.1

        there is a solution for my problem?

        I think $materialmapping_table_xml is no a problem, because the output xml file is only 60mb

        really thanks

    Yes You are right, Spreadsheet::parseexcel not store the parsed data when start parse new file. The problem is libxml ($materialmapping_table_xml).. strange because the xml output is only 60 mb.... yes I try your solution "that writes each $materialmapping_item to a file", can you help me to do it? :) Thankyou Moritz
