Re: Using HTML::Parser for simple tag removal

#!/usr/bin/perl -w
[download]

is the same thing as

use warnings;
[download]

Maybe you typo-ed, but I think what you want is use strict;
You may also want use CGI qw/:standard/;

That's not true. `use warnings` is blocked-scoped or file-scoped if not in a block, while `-w` will affect modules too. `>type script.pl use warnings; use Bla; Bla->test(); >type bla.pm package Bla; sub test { print(undef); } 1; >perl script.pl >perl -w script.pl Use of uninitialized value in print at Bla.pm line 5.` [download] `-w` is actually equivalent to `BEGIN { $^W = 1 }` at the top of your script. What you should have said is that `use warnings` is redundant when using `-w`.	[reply] [d/l] [select]

#!/usr/bin/perl -w is the same thing as use warnings; Not exactly. If you are using an old version of perl 5.005 you need to do -w and not "use warnings;". You should "use strict;" ------------------------------------- Nothing is too wonderful to be true -- Michael Faraday	[reply] [d/l]

Not sure either one of those makes a difference. And `use warnings;` is not a typo. And I was under the impression that `-w` was not the same in that it was a lot more broad in scope. Anyway.... And didn't know HTML::Parser needed CGI. —Brad "The important work of moving the world forward does not wait to be done by perfect men." George Eliot	[reply] [d/l] [select]
