Regex - Matching Multiline Comments

[anilga]

Hi ,

I am a starter with perl on windows.
I need to match commented lines like below

/* comments
* comments
comments */

Whats the exact reg exp in windows perl script to use for this.

I tried
($parm eq "\/*.*\n")
$parm =~ \^\/*.*\n/

Please let me know if you have a solution.

Thanks
Anilga

the * is a special character in a regexp, if you want to match it you must escape it:

if (/^\/\* \w+/)

matches: "/* comment"

but by looking at what you posted you either made a mistake or don't understand how to write a reular expression because this is incorrect:

$parm =~ \^\/*.*\n/

Hi,

Thanks for the comments. I tried this:

while ($parm = <FILE>) {
 
    if( $parm eq /^\/\* \w+/) {
        next;
    }
    print $parm;
 

and I couldn't match.

if( $parm =~ /^\/\* \w+/)

You can probably use the following reference to get what you want. It will help if you get some understanding of regular expressions before using this.
