Hello holy ones, I am working on a piece of code which will extract an image tag from an HTML doc I've read-in from my hard-drive. The '$i' index in the array is throwing a 'global symbol "$i" requires explicit package name..'. Here's the code: 
#!/usr/bin/perl
#htmltest2.plx
# Program will read in an html file, remove the img tag and print out
# no need for file variable yet: open (INFILE, "<".$htmlFile) or die("
+Can't read source file!\n");
use warnings;
use diagnostics;
use strict;

my @htmlLines;
open INFILE, "E:\\Documents and Settings\\Richard Lamb\\My Documents\\
+HTMLworkspace\\HTML practice\\My First Page!\\firsttest\.html" or die
+ ("Sod! Can't open this file.\n");
@htmlLines = <INFILE>;

scrapTag(); # calls method to remove image tags

sub scrapTag  # removes image tags from HTML document
{
  while($htmlLines[$i] =~ m/<IMG\s+([^>]+)>/ig) # finds each instance 
+of image tag in the input file
  {

    s/<IMG\s+([^>]+)>/ig//ig # replaces each instance of image tag wit
+h nothing!
  }
}

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

print "\n\n";
sleep 2;
print "Success?!\n";

Where am I going wrong, folks? Cheers, Richard
