Extract Multiple Tags

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

Scenario:

The following text belongs to a .doc file


File: check1.asm

Function: Monks

Tag: No
Tag: 001

Tag: Yes
Tag: 002

File: check2.asm

Function: Perl Monks

Tag: Yes
Tag: 003

Tag: No
Tag: 004

File: check3.asm

Function: Experts
Tag: No
Tag: 005

Tag: No
Tag: 006

Function: Perl Experts

Tag: No
Tag: 007

Tag: Yes
Tag: 008

I have to extract the tag which have been tagged as Yes and the corresponding function and file name to an excel sheet..

The output have to be like this:

Tags      Function     File
002       Monks        check1.asm
003       Perl Monks   check2.asm
008       Perl Experts check3.asm
[download]

I have written the following snippet for extracting the tag which is categorized as Yes :

use strict; 
use warnings;
use Win32::OLE;
use Win32::OLE qw(in with);
use Win32::OLE::Variant;
use Win32::OLE::Const 'Microsoft Excel';
use Win32::OLE::Const 'Microsoft Word'; 
use Cwd;
use File::Find;
use Win32::OLE;
use Win32::OLE::Enum;
$Win32::OLE::Warn = 3;                                # die on errors.
+..


my $out_file = 'check.xls';

open my $out_fh, '>', $out_file or die "Could not open file $out_file:
+$!";

my $print_next = 0;
 
 #Globals
our $Word;
our $reviewchklists;
my @scriptfiles;



@scriptfiles=glob('*.doc');
foreach my $file (@scriptfiles)
{ 
    
    my $var;

    
    my $filename = "D\:\\";
    $var = $filename."$file";
    print $var ;
    my $document = Win32::OLE -> GetObject("$var");

    print "Extracting Text ...\n";
    my @array;
    my $paragraphs = $document->Paragraphs();
    my $enumerate = new Win32::OLE::Enum($paragraphs);
    while(my $paragraph = $enumerate->Next())
    {

        my $text = $paragraph->{Range}->{Text}; 
          $text =~ s/[\n\r\t]//g;
          $text =~ s/\x0B/\n/g;
          $text =~ s/\x07//g;
      
         
         chomp $text;
        
        my $Data .= $text;
        
        @array=split(/\.$/,$Data);
        
        foreach my $line( @array)
        {
                
              if ($print_next)
              {
                print $out_fh $line."\n"  ;  # we add a "\n"  ;  #No n
+eed to chomp - we print the "\n"
                  local $\ = "<br>\n";
                local $/="\n\n";
                }
                $print_next =  ($line =~ /^Tag\sYes/);
                
        }
 
    }

 }       #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The above snippet is printing the output as follows:

ID : 002
ID : 003
ID : 008

I dont want the ID to be printed and how to extract the corresponding function and file name?

Help out monks!!!

When I saw this post, I thought: oh gosh this looks familiar. Anon Monk has given us a link to another post that looks virtually identical. If you are working on homework, a better strategy would be to "come clean" about it (admit it). And then ask a general question about the technique that you attempting rather than asking: "what's wrong with my homework code"? In this case, you are wondering about how to parse the input and extract some info. But that isn't the way that the question is framed. I guess if you are trying to "cheat", you at least need to become smarter about how you do it! Asking a general question about a specific technique is not "cheating" and will often generate a lot of responses especially if you have some working code albeit awkward. Ask a "how do I approach problem X?" question rather than a "please fix my homework" question.	[reply]

Here is an approach that worked on the data you provided. I think it would replace your `foreach` loop. Although, I'm not sure how you want your data printed with a '<br>' at the end of each line. #!/usr/bin/perl use strict; use warnings; use 5.014; my ($file, $function, $tag); printf "%-5s%-15s%s\n", qw/ Tags Function File /; my @line = <DATA>; for my $i (0 .. $#line) { if ($line[$i] =~ /^File: (.+)$/) { $file = $1; } elsif ($line[$i] =~ /^Function: (.+)$/) { $function = $1; } elsif ($line[$i] =~ /^Tag: Yes$/) { ($tag) = $line[$i+1] =~ /(\d+)$/; printf "%-5s%-15s%s\n", $tag, $function, $file; } } __DATA__ File: check1.asm Function: Monks Tag: No Tag: 001 Tag: Yes Tag: 002 File: check2.asm Function: Perl Monks Tag: Yes Tag: 003 Tag: No Tag: 004 File: check3.asm Function: Experts Tag: No Tag: 005 Tag: No Tag: 006 Function: Perl Experts Tag: No Tag: 007 Tag: Yes Tag: 008 [download] Outputs `Tags Function File 002 Monks check1.asm 003 Perl Monks check2.asm 008 Perl Experts check3.asm` [download]	[reply] [d/l] [select]
