Hi
I am parsing a pattern '<default>any text</default>' pattern in a file and wherever found, I want to replace that by '<default>enabled</default>'.
Now the problem is the above mentioned pattern may occur in a single line and in multiple line as well. So the input file may look something like

******* inputfile****************
this is line 1
this is line 2
<default>sometext</default>
this is line 3
<default>some more text
some more in next line
</default>
this is last line
*************************************
I am trying with this, which is working when the pattern is in single line but not for multiple line. The code for multiple line tried is commented out. 


use strict;
use warnings;
use Tie::File;

my $file = "inputfile";
 
my @array;

tie @array , 'Tie::File', $file ;

my $start = '<default>';
my $end   = '</default>';
my $val   = 'enabled';
my $replace = $start.$val.$end;
print "replace $replace \n";

for (my $i = 0 ; $i <= $#array ; $i++)
{
    #below if block is tried for multiple line pattern but not working

    # if ($array[$i] =~ /^<default>/../<^\/default>/)

    if($array[$i] =~ /^<default>/) #this is working
    {
        
        $array[$i] =~ s/^<default>.*<\/default>/$replace/g;
        

    }

}
untie @array;

seeking help on how can it be made to match both the patterns ?
