Hi Monks, With xml:libxml and Spreadsheet::ParseExcel and the command " $materialmapping_table_xml->createElement("item"); " I generate lines from excel document. for example: 
 
<item pr_1="a" pr_2="2" internal="co_1" pr_family="2" />
<item pr_1="b" pr_2="2" internal="co_1" pr_family="2" />
<item pr_1="c" pr_2="2" internal="co_1" pr_family="2" />
<item pr_1="a" pr_2="1" internal="co_1" pr_family="2" />
<item pr_1="b" pr_2="1" internal="co_1" pr_family="2" />
<item pr_1="c" pr_2="1" internal="co_1" pr_family="2" />
<item pr_1="a" pr_2="2" internal="co_1" pr_family="2" />
<item pr_1="b" pr_2="2" internal="co_1" pr_family="2" />
<item pr_1="c" pr_2="2" internal="co_1" pr_family="2" />

<item pr_1="c" pr_2="2" internal="co_1" pr_family="2" />
