perl generated table - format color

casperdaghost has asked for the wisdom of the Perl Monks concerning the following question:

Oh fellow seekers of wisdom..We shape clay into a pot, but it is the emptiness inside that holds whatever we want.....
The code below breaks up the @stat_array into fours and then prints out fields in to an HTML table wih the OCOMsg2 cell in red - again - just one cell of the emailed table. print Dumper @stat_array_rows; sleep 1; exit; The boss told me that he wants the WHOLE LINE with the OCOMsg2 in red - so the array below, all the elements - "ibfarm102 - localtick", 'New York", "hibmis100 - procHKHD2 - Hongkong", "OCOMsg2" need to be red. print Dumper @stat_array_rows; sleep 1; exit; Is there a way to do this with out rewriting the whole block - I really like this block..

@stat_array = ("ibfarm102  - localtick", "Boston" , "hibmis100 -  proc
+HKHD2 - Hongkong", "PidMonRsp", 
"eufarm102  - localtick", "London", "hibmis100 -  procHKHD2 - Hongkong
+" , "PidMonReq" , 
"ibfarm102  - localtick", "New York" , "hibmis100 -  procHKHD2 - Hongk
+ong", "PidMonRsp", 
"ibfarm102  - localtick", 'New York", "hibmis100 -  procHKHD2 - Hongko
+ng", "OCOMsg2"); 
my @stat_array_rows = @stat_array;
while (my @stat_array_rows = splice(@stat_array_rows, 0 , 4)) {
  print MAIL "<tr>\n";
  for my $stat_row(@stat_array_rows) {
     #if ($stat_row eq $config_msgtype){
     if ($stat_row =~/OCAlive2/){
        print MAIL "<td><font color=red>$stat_row[0]</font></td>\n";
     }
     else {
        print MAIL "<td>$stat_row</td>\n";
     }
  }
  print MAIL "</tr>\n";
}

this are the results of the block:

<tr>
<td>ibfarm102  - localtick </td>
<td> Boston</td>
<td> hibmis100 -  procHKHD2 - Hongkong </td>
<td>PidMonRsp</td>
</tr>
<tr>
<td>eufarm102  - localtick </td>
<td>London</td>
<td> hibmis100 -  procHKHD2 - Hongkong </td>
<td>PidMonReq</td>
</tr>
<tr>
<td>ibfarm102  - localtick </td>
<td>New York</td>
<td> hibmis100 -  procHKHD2 - Hongkong </td>
<td>PidMonRsp</td>
</tr>
<tr>
<td>ibfarm102  - localtick </td>
<td>New York</td>
<td> hibmis100 -  procHKHD2 - Hongkong </td>
<td>OCOMsg2</td>
</tr>

this is the data Dumper

print Dumper @stat_array
$VAR1 = [
         'ibfarm102 localtick',
         ' Greenwich',
         ' hibmis100 procHKHD2 Hongkong ',
         'PidMonRsp'
       ];
print Dumper @stat_array_rows. 
$VAR1 = 'ibfarm102 localtick';
$VAR2 = ' Greenwich';
$VAR3 = ' hibmis100 procHKHD2 Hongkong ';
$VAR4 = 'PidMonRsp';

Just move the condition outside the loop; if you know what member of a row to test, test just that (i.e. `$stat_array_rows[2]`, otherwise you can use grep. Your code is buggy: why do you use `$stat_row[0]`, when the only `stat_row` variable is a scalar? Use strict and warnings!	[reply] [d/l] [select]

And what are the results that you want (html)?	[reply]

The best way to get "red," etc. is with a CSS stylesheet. Let the Perl script output the data without regard to how it looks, but adding "class=" if necessary.	[reply]

As you loops through your data, you need to determine if a given row contains the "OCOMsg2" field you're looking for, and if it does write out the following: `<tr style="color: red;">` [download] Otherwise, just write out a plain tr tag with no style attribute. You need to do this before splitting the row into individual parts - or else use join to put them back together in order to do the check. Something like this: use strict; my @stat_array = ( "ibfarm102 - localtick", "Boston" , "hibmis100 - procHKHD2 - Hongkong", "PidMonRsp", "eufarm102 - localtick", "London", "hibmis100 - procHKHD2 - Hongkong", "PidMonReq", "ibfarm102 - localtick", "New York", "hibmis100 - procHKHD2 - Hongkong", "PidMonRsp", "ibfarm102 - localtick", "New York", "hibmis100 - procHKHD2 - Hongkong", "OCOMsg2" ); while (my @group_of_4 = splice(@stat_array, 0 , 4)) { my $rowstring = join(' ', @group_of_4); if ($rowstring =~ /OCOMsg2/) { print MAIL "<tr style=\"color: red;\">\n"; } else { print MAIL "<tr>\n"; } for my $data (@group_of_4) { print MAIL "<td>$data</td>\n"; } print MAIL "</tr>\n"; } [download] I get this output: `<tr> <td>ibfarm102 - localtick</td> <td>Boston</td> <td>hibmis100 - procHKHD2 - Hongkong</td> <td>PidMonRsp</td> </tr> <tr> <td>eufarm102 - localtick</td> <td>London</td> <td>hibmis100 - procHKHD2 - Hongkong</td> <td>PidMonReq</td> </tr> <tr> <td>ibfarm102 - localtick</td> <td>New York</td> <td>hibmis100 - procHKHD2 - Hongkong</td> <td>PidMonRsp</td> </tr> <tr style="color: red;"> <td>ibfarm102 - localtick</td> <td>New York</td> <td>hibmis100 - procHKHD2 - Hongkong</td> <td>OCOMsg2</td> </tr>` [download] If that's not what you want - hopefully it's enough to get you going in the right direction.
