Here is the updated code,

the reason why it didn't work in the first phase is that, input format was different, there were no 'line feeds' in the sample file provided.

Now it should work!

Let us know how it proceeds!

Code:
#! /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

Parse a string in XML file using shell script

Hi Matrixmadhan,

You're so brilliant! I wish I can be like you when it comes to writing scripts (wink* wink*). Sad to say I'm not gifted Smilie One more thing, what if the values of calling or other headers are more than 3 characters? Let's say 12? How can I modify the script to arrange the values and headings allignment? So that the values and the headings are on the same column? I hope my question is clear. Thank you so much for helping me and taking time to create this script!

this is quite confusing and I believe you are saying about alignment of the column header and the data in a unified way.

That should be quite easy to modify in the script, try it out, if you have any difficulty in that, please post a sample output you wish to have Smilie

Parse a string in XML file using shell script

Hi Matrixmadhan,

Another question, what if the file that I will use will come from the output of a command? Instead of specifying a in (open(FILE, "<", "a")Smilie, I need to get the file a which will be the output of a command. How can I modify the script to do that? Thank you so much!


sed -n 1p /home/user/scripts/file.txt
sample.txt

sed -n 1p /home/user/scripts/file.txt
sample.txt
you could change it as,

Code:
my $command = "sed -n 10 file.txt |";
open(PIPE, "<", "$command") or die "Unable to open file\n";
