in thread remove node information by searching tag element.

Given your output data, the approach I provided will do the job. $key should be the 'number tag element'. Don't add the results if you have already seen the number.

This block of code illustrates the technique.

my @data = qw( a b 3 d a f b ); my %seen; for ( @data ) { print $_, "\n" unless $seen{$_}++; } __DATA__ a b 3 d f

You should be able to apply this technique to your problem space.
