Grouping Multiple Occurences

rajkrishna89 has asked for the wisdom of the Perl Monks concerning the following question:

i have written a script which will extract the tags from a .doc file..

The format of the doc is

ID:001

Class:

Check1

Class:

Check2

ID:002

Class:

Check3

Class:

Check4

im getting the output in excel as below

Class ID

Check1 001

Check2 001

Check3 002

Check4 002

I want the output to be displayed as below:

Class ID

Check1 001

Check2

Check3 002

Check4

If there are multiple occurences (Classes) of same ID, the ID have to be written only once

The snippet is

my $i;
for ($i = 0; $i <@array; $i++)
    {
    if($array[$i] =~ /^Count\:\s /)
        {
                $Count_Name = $1;
                for ($count = $i; $count >= 1; $count--)
                {   
                    if ($array[$count] =~ /ID:\s*(.+)/ )
                    {
                        $ID = $1;
                        my $Mycell1 = $Sheet->Range($Sheet->Cells($row
+, $col),$Sheet->Cells($row, $col+2));
                        $Mycell1->{Value}=["Count_Name","$ID"];
                        $row++;
                        # print $out_fh $sdd."\t".$Fun."\t".$File."\n"
+;
                        goto breakingfunction;
                    }
                }    
breakingfunction:            
            }        
        }
    }

You may want to rethink your data structure: How do I make a hash of arrays? Your key is the ID and values are the Classes.	[reply]

`#! /usr/bin/perl open(FILE,"<pmregex.txt"); my @lines=<FILE>; close(FILE); print "Class ID\n"; my $found=0;my $id; foreach my $line(@lines) { if($line=~ /ID:/) { $id=$'; chomp($id); $found=0; } if($line=~ /Check./) { print "$&"; if($found==0) { print " $id";$found=1; } print "\n"; } }` [download] output `Class ID Check1 001 Check2 Check3 002 Check4` [download] your code seems complex to me so i have written my own use flag if you want to print a id only once	[reply] [d/l] [select]
