This isn't as concise as the first example above, but it's an example of how to use a Schwartzian Transform (which I'm just beginning to learn).
use strict;
use warnings;
my @data = ('#Comment', '*ss id addr id: 099 bbb ccc aaa', '*ss id add
+r id: 003 aaa bbb ccc', '#Comment', '*333 23 ss id: 002 aaa bbb ccc',
+ '*22 233333333 34432 233 44');
my @id= ();
foreach my $entry (@data){
if($entry =~ /id:/){
push(@id, $entry);
}
}
my @sortedid = sort {$a->[1] <=> $b->[1]} map{[$_,/id:\s*(\d+)/]} @id;
foreach my $entry (@data){
if($entry =~ /id:/){
my $sort = shift(@sortedid);
print $sort->[0];
}else{
print $entry;
}
print "\n";
}
Produces the same output as above:
#Comment
*333 23 ss id: 002 aaa bbb ccc
*ss id addr id: 003 aaa bbb ccc
#Comment
*ss id addr id: 099 bbb ccc aaa
*22 233333333 34432 233 44
