Have you taken a look at the perldoc page for grep in Perl? You will note that your grep statement should actually be coded as follows:

@contents = grep {!/<SEC-HEADER>.*</SEC-HEADER>/} @contents;

As for "not working", can you please elaborate? What are you seeing that is going wrong and what are you expecting to see?

Your code has syntax errors and does not compile. Please post the actual code you are running.

You should have also posted a small snippet of your input file. Here is my guess: your input file has start and end tags on different lines. Consider:

Expand|Select|Wrap|Line Numbers

 use warnings;

use strict;
 
my @contents = <DATA>; 

@contents = grep { !/<SEC-HEADER>.*<\/SEC-HEADER>/ } @contents; 

print @contents;
 
__DATA__

<html>
 
<SEC-HEADER>foo</SEC-HEADER>
 
<SEC-HEADER>

bar</SEC-HEADER>
 
</html>

This prints out:

Expand|Select|Wrap|Line Numbers

 <html>
 
<SEC-HEADER>

bar</SEC-HEADER>
 
</html>

In any case, you really should use one of the HTML parser modules from CPAN instead of regular expressions.
