Re: [skysurf] iterating through an array using XML::Simple
|
|
|
A short test under de Perl debugger:
DB<8> @c = qw /foo bar baz/
DB<9> x @c
0 'foo'
1 'bar'
2 'baz'
DB<10> $i = 0
DB<11> print $c['$i']
foo
DB<12> $i = 1
DB<13> print $c['$i']
foo
DB<14> $i = 2
DB<15> print $c['$i']
foo
DB<16> print $c[$i]
baz
As you can see, when I use '$i' as index of the array, I get only the first element of the array, irrespective of the value of $i, as if '$i' was evaluated to 0 in this context (which happens when you evaluate a string in a numeric context). You really need to remove the single quote marks.
With double quote marks, it would work:
DB<17> print $c["$i"]
baz
I think that your use of an array slice is also probably an error. You should probably prefix your array name with $ instead of @ (on the line where you are using the $i subscript).
