Here' the problem, brothers:

I have a small script which will (soon) change font size attributes with values of 14 to 16. I declare an array to hold the HTML, open and insert the HTML file into the array and call a wee sub to alter the values.

I'm doing something blatantly, frustratingly wrong and I cannot see it (I think).Should I be declaring and initialising a scalar containing the pattern, and then substitute one for the other.

Here's the code: 
#!/usr/bin/perl
# change font sizes.plx
# Program will read in an html file, change font sizes and print chang
+es to DOD command screen.
# 1. No need for file variable yet: open (INFILE, "<".$htmlFile) or di
+e("Can't read source file!\n");
# 2. /font-size:\s*[0-9]+pt;?/ig
use warnings;
use diagnostics;
use strict;

# Declare and initialise variables.
my @htmlLines;

# Open HTML test file - forward slashes do not need to be escaped.
open INFILE, "E:/Documents and Settings/Richard Lamb/My Documents/HTML
+/test1InLineCSS.html" or die "Sod! Can't open this file.\n";
# Assign to an array/list variable.
@htmlLines = <INFILE>;
close (INFILE);

changeFontSize();
# Alter attribute values
sub changeFontSize
{
  foreach my $line (@htmlLines)
  {
    $line =~ s/font-size:\\s*14pt;?/font-size:\\s*18pt;?/ig;  # case i
+nsensitivity and global search for pattern
  }
}

printHTML(); # prints the reformatted HTML file in DOS window

sub printHTML
{
  for my $i (0..@htmlLines-1)
  {
    print $htmlLines[$i];
  }
}

Cheers folks,
