Get data from pdf form

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

Is it possible to extract the filled Data from a pdf form? I have multiple filled out pdf form files and want to access the data filled in. I tried with CAM::PDF :

use strict;
use warnings;

use CAM::PDF;
 
my $pdf = CAM::PDF->new('file.pdf');

my @formfields = $pdf->getFormFieldList();

foreach (@formfields)
    {
    print $_."\n";
    }

exit;
[download]

But i can't filter the form fields or get there content. Is there a way to do this?

If you data dump the objects you might be able to find the data. Try `use strict; use warnings; use Data::Dump 'pp'; use CAM::PDF; my $pdf = CAM::PDF->new('file.pdf'); my @formfields = $pdf->getFormFieldList(); foreach (@formfields){ my $obj = $pdf->getFormField($_); #pp $obj; printf "%s = %s\n",$_,$obj->{value}{value}{V}{value}; }` [download] poj	[reply] [d/l]

Read the fine documentation which includes the note, "`Many example programs are included in this distribution to do useful tasks. See the bin subdirectory."` *Questions containing the words "doesn't work" (or their moral equivalent) will usually get a downvote from me unless accompanied by:* code verbatim error and/or warning messages *a coherent explanation of what "doesn't work* actually means.**	[reply]
