Hi Rob,
Thank you for that input. I was also enable to successfully complete the
same with the below script. (its a mix up from various scripts :D)
$file1 ="XXXX"; # input file
$file2="XXXX.new";
my $flag=0; #output file
open(INFO,"$file1"); # Open the first file
open(OUT,">$file2"); # open the second file
my $t2="\/resource-ref>";
chomp ($t2);
while (my $line=<INFO>)
{
chomp($line1);
if ($line =~ /<resource-ref/ and $line =~ /DataSource_/ and $flag==0)
{
print "$line\n";
#print OUT "$line";
$flag=1;
}elsif ($line =~ /$t2/ and $flag==1)
{
$flag=0;
}elsif ( $flag==0)
{
print OUT "$line";
}
}
close(INFO);
close(OUT);
Depending on what i give as param for t1 and t2 i will be able to manipulate
what i want to delete.
I am just posting this as there may be a possibility someone may not be able
to use the libraries.
