it worked great, Could you explain the usage of &
I found it
/regexp(3,n)/replacement/
Attempt to match regexp(3,n) against the pattern space. If success-
ful, replace that portion matched with replacement. The
replacement may contain the special character & to refer to that
portion of the pattern space which matched, and the special
escapes \1 through \9 to refer to the corresponding matching
sub-expressions in(1,8) the regexp(3,n).

Excel::Template::Container::Loop(3pm)			User Contributed Perl Documentation		     Excel::Template::Container::Loop(3pm)

NAME
Excel::Template::Container::Loop - Excel::Template::Container::Loop PURPOSE
To provide looping NODE NAME
LOOP INHERITANCE
Excel::Template::Container ATTRIBUTES
o NAME This is the name of the loop. It's used to identify within the parameter set what variables to expose to the children nodes each iteration. CHILDREN
None EFFECTS
None DEPENDENCIES
None USAGE
<loop name="LOOPY"> ... Children here ... </loop> In the above example, the children nodes would have access to the LOOPY array of hashes as parameters. Each iteration through the array would expose a different hash of parameters to the children. These loops work just like HTML::Template's loops. (I promise I'll give more info here!) There is one difference - I prefer using Perl-like scoping, so accessing of variables outside the LOOP scope from within is perfectly acceptable. You can also hide outside variables with inner values, if you desire, just like Perl. AUTHOR
