OK, got a result, but not easily. I seem to be missing how to descend an xml tree and pick out the element I want to operate on. What I have is: 
#!/usr/bin/perl

use strict;
use warnings;
use XML::LibXML;

die "Usage: $0 filename \n";
   unless ( @ARGV > 0 );

my $xml_file = shift;
my $xml      = XML::LibXML->new;
my $dom      = $xml->parse_file( $xml_file );
my $root     = $dom->documentElement;

my @logins = grep { $_->nodeType == XML_ELEMENT_NODE } $root->childNod
+es;
foreach my $login ( @logins ) {
   my @user_infos = grep { $_->nodeType == XML_ELEMENT_NODE } $login->
+childNodes;
   foreach my $user_info ( @user_infos ) {
      my @add_users = grep { $_->nodeType == XML_ELEMENT_NODE } $user_
+info->childNodes;
      foreach my $add_user ( @add_users ) {
         $add-user->removeAttribute( "USER_NAME" );
         $add-user->removeAttribute( "PASSWORD" );
      }
   }
}
my $output = $dom->toString(0);
$output =~ s/(?<=\n)\s*\n//g;
open ( my $FH, '>', 'newilo2' ) or die "Could not open file newilo2 $!
+";
print $FH $output;
close $FH;

I tried using findnode, but I get an error about perl not being able to find that method. So, thanks for the pointer! It at least is getting me the results I want. :)
