So, I have an "isolated system" (not internet connected) under "configuration management" with perl on it. I have an XML file that I'd like parse the extract and format specific information from it.

"Normally" I'd install some XML perl module. But being "isolated" I can't download it. And even if I was able to "configuration management" says no new software without a shit ton of red tape just for a few little packages. Scripts that an admin writes in an exception.

The XML file is a Nessus scanner results file. The section that I want to extract are between <RemoteHost> and </RemoteHost> for several servers in the file. For each RemoteHost section I'd like to only pull sections like the hostname, CVEs (list), and synopsis (multi line).

I've tried using the flip-flop operator but it just gives me everything. If there's a way to pick and choose what parts I want; I don't know how to do it.

Any suggestions?

#! /usr/bin/perl

use strict;
use warnings;
use FileHandle;

my $file;

if (-e $ARGV[0]){
     $file = $ARGV[0];
     hostreport();
} else {
     die;
}

sub hostreport {
     open(my $fh, "<file");
     while (<$fh>){
          print if (/^\<ReportHost/../^\<\ReportHost>/);
     }
}

print $file;
