( #3333=superdoc: print w/replies, xml ) Need Help??

map works... but there is a feeling that it is not needed. If I do it, I will simply:

use strict; use warnings; use Data::Dumper; my $AoH_orig = [ { 'title' => 'aaa-aaa', 'name' => 'tom' }, { 'title' => 'bbb-bbb', 'name' => 'kathy' }, { 'title' => 'ccc-ccc', 'name' => 'bill' } ]; for (@$AoH_orig) {$_->{'title'} =~ s/-/_/g}; print Dumper($AoH_orig);

Which gives you what you wanted:

$VAR1 = [ { 'name' => 'tom', 'title' => 'aaa_aaa' }, { 'name' => 'kathy', 'title' => 'bbb_bbb' }, { 'name' => 'bill', 'title' => 'ccc_ccc' } ];
