printing the elements of a 2D array into an HTML table

[goude]

Hello everyone,

I hope someone can help me out with the following.
I have a 2D matrix with size 20x8 (20 rows & 8 columns) and I'm trying to print each element to an HTML file. The easiest way to do that is to print each line separately:

1st Row
print "<TR> <TH>pac1</TH> <TH>$data[0][0]</TH> <TH>$data[0][1]</TH> <TH>$data[0[2]</TH> 
          <TH>$data[0][3]</TH> <TH>$data[0][4]</TH> <TH>$data[0][5]</TH> <TH>$data[0][6]</TH> </TR>";

2nd row
print "<TR> <TH>pac2</TH> <TH>$data[1][0]</TH> <TH>$data[1][1]</TH> <TH>$data[1]2]</TH> 
         <TH>$data[1][3]</TH> <TH>$data[1][4]</TH>  <TH>$data[1][5]</TH> <TH>$data[1][6]</TH> </TR>";

It works fine this way. However I know that with a for loop you can simplify things and instead of writing 20 print statements you can do it in a few lines. Can anyone tell me how I can achieve this, please? How should I go about it? I find it a bit tricky to apply a for loop in this case. I tried using a foreach loop like that:

print "content-type: text/html \n\n";	#The header

# SET A COUNT VARIABLE
$count = pac1;  

# BEGIN THE LOOP
foreach $data(@data) {
	#print "<tr><th>$count</th><th>$data</th></tr>";
       $count++;
}

but the result I get is a 20x2 table instead of 20x8 and the elements comes up as hexadecimal No idea why this is happening.

pac1	ARRAY(0x628ea0)
pac2	ARRAY(0x628f60)
pac3  	ARRAY(0x629030)
pac4	ARRAY(0x629100)
pac5	ARRAY(0x6291d0)
pac6	ARRAY(0x6292a0)
pac7	ARRAY(0x629370)
pac8	ARRAY(0x629440)
pac9        ARRAY(0x629510)
pac0        ARRAY(0x6295e0)
pac1        ARRAY(0x6296b0)
pac2         ARRAY(0x629780)
pac3        ARRAY(0x6298f0)
pac4        ARRAY(0x629a40)
pac5        ARRAY(0x629850)
pac6        ARRAY(0x631470)
pac7       ARRAY(0x631540)
pac8       ARRAY(0x631610)
pac9       ARRAY(0x6316e0)
pac0     	ARRAY(0x631850)

Any suggestions please?
Thanks a lot guys

1. Create a python script, let's call it t2h.py

#!/bin/env python
import fileinput

def gen_html():
	HTML=""
	row_count=1
	for line in fileinput.input(inplace=False):
		TH=['pac'+str(row_count)]
		for word in line.split():
			TH.append( '<TH>'+word+'</TH>' )
		ROW="".join(th for th in TH)
		HTML+="<TR>"+ROW+"</TR>\n"
		row_count+=1
	return HTML

if __name__=="__main__":
	print gen_html()

2. use t2h.py to process your data file, any of the following should return the same results:
cat data|python t2h.py
python t2h.py < data
python t2h.py data

So I think you're using Perl?

If you have a list of lists in Perl, what you actually have is a list of arrayrefs. An arrayref is basically a scalar that points to an actual array. You're on the right track, but you missed one element.

You have a list of lists. The first list contains a bunch of rows. Each row (lists inside the main list) contains a bunch of columns. Recognizing this, our code becomes simple:

#!/usr/bin/perl

print "content-type: text/html \n\n";	#The header

# SET A COUNT VARIABLE
$count = 1;

# BEGIN THE LOOP
foreach $row (@data)
{
    print "<tr>";
    print "<td>$count</td>";
    foreach $col (@$row)
    {
        print "<td>$col</td>";
    }
    print "</tr>";
    $count++;
}

You see? We loop through every element of the inner loops as well, and thus get all of our data.

Does this help?

I know it's a bit late now but thank you guys for the help.
