Code:
It's me again!

It's me again too ! Smilie

there are two ways,

1) perl scriptname >> append_file

2) within the script

Code:
open(APP_FILE, ">>", $append_file) or die "Unable to open file $append_file <$!> \n";
print APP_FILE "$contents";

close(APP_FILE);

Parse a string in XML file using

Hi Matrixmadhan,

I tried your solution but what it prints is the copy of the script and not the result of the script that you created before. What I want to do is instead of seeing the output of the script on the server, I want to append the result of the script in to a file let's say that the output of the script will save it in filename outputfile.txt. How can I include that in the script that you created before? Thanks a lot for answering all my queries!


#! /opt/third-party/bin/perl

my $c = 0;

open(FILE, "<", "sample.txt");

while(<FILE>) {
chomp;
my @arr = split(/></);
foreach (@arr) {
if( /xml version/ ) {
$c++;
print "\n";
}
if( />/ && /</ ) {
if( $c == 1 ) {
s/(.*)>(.*)<.*$/\1|\2/;
my($tmp1, $tmp2) = split(/\|/);
$data .= (" " . $tmp2);
printf "%s ", $tmp1;
}
else {
s/(.*)>(.*)<.*$/\2/;
printf "%s ", $_;
}
}
}
print "\n";
print "$data\n" if( /xml version/i );
}

close(FILE);

exit 0

printf OUTPUT "%s ", $_;
}
}
}
print OUTPUT "\n";
print OUTPUT "$data\n" if( /xml version/i );
}

close(FILE);

exit 0

open the file,

change file handle from STDOUT to the specific file handle

the above code would work.

Please do use CODE tags ! Smilie

Parse a string in XML file using shell script

Hi Matrixmadhan,

You're really great! Sorry I always disturb you. I really don't know how I can finish this script. It's complicated for me because I'm just starting to learn perl and I'm not really good in creating scripts. Thanks so much! Hope I can still ask for help next time.

Sure !

So what is the complication involved in the script ?

We would try to help you. Smilie

Parse a string in XML file using

Hi Matrixmadhan,

My problem with the script is that I want the script to run only if there's a new CDR to process which is the CDR before CDR*.tmp. The *.tmp is where the current CDR is being processed that's why I'll just process the last completed CDR (last CDR without .tmp). The list of CDRs below are the input files on the script that you've created. Please see also the whole script below. Thanks again for all the help! Smilie

first, please use the CODE tags - they are provided to look into the code much easily

I just understood your requirement partially, help me in understanding the remaining

I assume the list of files that is provided is the output of

Code:
cat cdr.txt

Code:
chomp(@inputfayl = `cat cdr.txt`);
while (<@inputfayl>) {
if (/CDR/) {
$inputfayl=$_;
}
}

From the above only the file in the last line of the file is selected

Now what is the file that needs to be processed and the file that shouldn't be processed
