Re: How do I parse data received from a textarea

Presumably you're receiving the data as "foo=HHH9114\nEEE8888\nLLL4258\nPPP8525". You can replace these newlines with double pipes with this code fragment.

# Put value part in default variable.
$_="HHH914\nEEE888\nLLL4258\nPPP8525";

# Search for newlines and replace with double pipes.
s/\n/||/g;

print "||$_||\n";

Prints out this:

||HHH914||EEE888||LLL4258||PPP8525||

Please note that what is sent for these "newlines" is dependent on what platform the browser is running on: `\r\n for Windows \n for Unix \r for Macintosh` [download] Impossible Robot	[reply] [d/l]

I'm not sure line separators differ with TEXTAREA fields no matter what OS is running on the machine with the Browser. In my own (less than vast) experience, I have had no problem using code like the following (AFAIK, has worked with Mac-, UNIX- and Windows-based browsers): `# assuming text is in $_ my @lines = split /\n/; my $text = join '\|\|', @lines; print "\|\|$lines\|\|\n";` [download] Or, in one line, `print '\|\|'. join('\|\|', split( /\n/ )) .'\|\|' ."\n";` [download] dmm If you GIVE a man a fish you feed him for a day But, TEACH him to fish and you feed him for a lifetime	[reply] [d/l] [select]
