Script to create simple html from text file
 
I am working on a script to convert a comma seperated text file into html code line by line.
I am a newbie with scripts (and programming in general)

The text file is like so:
Code:
link url, image url, description
and I want it to output this:
Code:
<td><a href=”link url”><img src="image url" alt=”description" /></a></td>
Here is what I have so far:
Code:
#!/bin/bash
var1='<td><a href=”'
var2='”><img src="'
var3='" alt=”thumbnail image" /></a></td>'
while read line
do
echo $var1$line$var2$line$var3
done < gallery.txt
It puts the entire line into the html so its no good. I'll probably need to use awk (I think).

Look into Ruby or Python, they both have a lot of libraries available specially for such tasks.

This'll do it in perl

Code:
use strict;
use warnings;

# Open the input file
open (my $fh, "<", "input.txt") or die $!;

# Loop around the file performing the replacements
while (<$fh>) {
        chomp;
        my ($url, $image, $description) = split /,/;
        print "<td><a href=\"$url\"><img src=\"$image\" alt=\"$description\"/></a></td>\n";
}

close $fh;
input.txt looks like this:

Code:
link1 url,image1 url,description1
link2 url,image2 url,description2

Assuming it's OK to modify gallery.txt, taking out the spaces after the commas (if not that can be fixed), this should do it
Code:
#!/bin/bash

while read line
do
    IFS=','
    array=($line)
    unset IFS
    echo '<td><a href=”'"${array[0]}"'”><img src="'"${array[1]}"'" alt=”'"${array[2]}"'" /></a></td>'
done < gallery.txt
EDIT: on second thoughts this is a bit tidier
Code:
#!/bin/bash

while IFS=',' read link_url image_url desc
do
    echo '<td><a href=”'"$link_url"'”><img src="'"$image_url"'" alt=”'"$desc"'" /></a></td>'
done < gallery.txt

Thanks guys.
I used the perl one. It works great!
