If you have n input features with "code" attribute containing 1-n, this workflow might help you. Assuming that the code of the first feature is 1.
XML Template Expression (common to both Root and SUB)
declare namespace inv="replace/this/with/actual/namespace.name";
let $i := xs:integer(fme:get-attribute("code"))
return
<inv:And>
<code>code {$i}</code>
{fme:process-features("SUB", "code", $i+1)}
</inv:And>

Dear Mr. Takashi, thank you for your advise. I am sorry I did not clarify that code is a string, but, I added a num column to the data and tried what is below in both Root and SUB expressions. I get the error below, and cannot see why as it is declared. So with num as an integer (1 to 74), code as a string, e.g, 333-22-2,5, and both columns in a spreadsheet, the following expression
declare namespace inv="<http://etc, etc/inv>";
let $i := xs:integer(fme:get-attribute("num"))
let $code := xs:string(fme:get-attribute("code"))
return
<inv:And>
<inv:code>{$code}</inv:code>
{fme:process-features("SUB","code",$i+1)}
</inv:And>
gives me these error messages:
XMLTemplater_2(XMLTemplaterFactory): "i": undefined undeclared variable
XMLTemplater_2(XMLTemplaterFactory): An error occurred while parsing the ROOT template..
If I understand your requirement correctly, this expression would work as desired.
declare namespace inv="replace/this/with/actual/namespace.name";
let $i := xs:integer(fme:get-attribute("num"))
return
<inv:And>
<inv:code>{fme:get-attribute("code")}</inv:code>
{fme:process-features("SUB", "num", $i+1)}
</inv:And>
