It's good that you're using strict and warnings;

This is an array of a single hash-reference with two keys - "name1" and
"name2". If you want to have name3 , name4 etc. the best thing would be to
point a key (say "name" at an array reference.
{
name =>
[
'http://www.abc.com/data/a/000/name1.txt',
'http://www.abc.com/data/a/000/name2.txt',
],
},

What are you trying to do here - for each key $name out of $element you print
its "name1" key. You probably want (untested):
«
print "$name --> $element->{$name}\n";

$links[0]{'name2'} , $links[0]->{'name2'} , $links[0]{name2} etc.

You probably mean that it should be the *value* of name2. For more information
