shell script help with HTML formatting (??)

cbtshare · 01-09-2010, 11:54 PM

I have a script that presents download link, but it shows download links in one line.How do I get it to show each link in its own line?

my $message_text =
join "\n",
map "<a href=\"$_->{download_link}\">$_->{download_link}</a>" ,

Any help, thanks

It looks like a Perl script and you must post more of it to get help.

thats basically the jist of it...

# Send upload notifications to watching users.
my $message_text =
join "\n",
map "<a href=\"$_->{download_link}\">$_->{download_link}</a>" ,
@arr;

}

but that prints the download links in one line.

I need it to be in two lines.

Replace the "\n" with "<br>", html mostly ignores whitespace.

thank but it didnt work
# Send upload notifications to watching users.

join "<br>",

Works for me:

Code:

#!/usr/bin/env perl -W
use strict;

my $link1 = {download_link => "aa"};
my $link2 = {download_link => "bb"};
my @arr = ( $link1, $link2 );
my $message_text =
join "<br>",
    (map ("<a href=\"$_->{download_link}\">$_->{download_link}</a>" ,
          @arr));

print($message_text . "\n");

The output is

Code:

<a href="aa">aa</a><br><a href="bb">bb</a>

which is two lines when viewed in Firefox.

my $message_text =
join "\n",
map "<a href=\"$_->{download_link}\">$_->{download_link}</a>" ,
@arr;

}

ist the code, you have 2 separate download links
my $link1 = {download_link => "aa"};
my $link2 = {download_link => "bb"};
and you join them, I only have one line

Then how does @arr get its value in your code? I don't know perl very well, what I posted was the only thing I could get to run without errors.

You need to show the rest of the code, so we can figure out what the value of @arr is. Or maybe a perl expert will be able to deduce it from what you've posted...
