I have the list of xml files in a directory.
The file format is such that some of the files have a same "name" and prefixed with the random numbers.
Out of those files, using the xml parser, check for the date and time tag.
How can I compare the files with same "name" and delete the file which have the less time 
filenames as 508.ids.xml
1508.ids.xml
1509.id123.xml
1400.id123.xml

#!/usr/bin/perl
use XML::Simple;
use ContentHelper;
use XML::Parser;

@files = `ls`;

# Sub substitution to check for duplicates
foreach $input_file (@grepNames){
        chomp $input_file;
        my $xml_parser = XML::Simple->new();
        my $data = $xml_parser->XMLin($input_file);
        my $Id = $data->{"root"}->{'id'};
        my $date = $data->{'root'}->{'date'};
        my $time = $data->{'root'}->{'time'};
### Please tell me how to add the condition here.
        print "$input_file:$Id:$time:$date\n\n";
        }

The above print command prints
9890.ids.xml:ids:70857:2004-10-02
9893.ids.xml:ids:70859:2004-10-02

9830.ids.xml:ids:2000:2004-10-02
9834.ids.xml:ids:4000:2004-10-01
