print multiple lines

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

I'm trying to print to a file, but this isn't working. How would I print multiple lines of html to a file w/o having to do a print statement for each line of html?

open(PB_BODY_LIMITED, "> $file_name") or die "Can't $!\n"; 

print PB_BODY_LIMITED 

"
<table width=600>
      <tr>
         <th colspan='2' class='top'>-- Perbill Search Results --</th>
      </tr>
      <tr>
         <th class='left'>Company</th>
         <td>$data[0]</td>
      </tr>
      <tr>
         <th class='left'>Company ID(302)</th>
         <td>$company_name_id</td>
      </tr>      
      <tr>
         <th class='left'> Docs</th>
         <td>$data[1]</td>
      </tr>
      <tr>
         <th class='left'> Bytes</th>
         <td>$data[2]</td>
      </tr>
      <tr>
         <th class='left'>From</th>
         <td>$from_month$from_day$from_year</td>
      </tr>
      <tr>
         <th class='left'>To</th>
         <td>$to_month$to_day$to_year</td>
      </tr>            
</table>

Probably the most common method is heredoc strings: `print F <<EOT; Here's one line and another line and even some "quoted" data... EOT` [download] I like to use EOT as my "here doc" string, but you can use anything you want to.	[reply] [d/l]

This is something that I do in one of my tools that I wrote: `open(FOUT,"> somefile.html" or die "$!"; print FOUT qq( <table width="770" cellpadding=0 ... -------8< snip! 8<-----------------` [download] other variants of this I have seen is to store the intended output in a single variable and just print the variable. There are many ways to do this. `++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Peter L.

Read perldata, search for the term "here-document" in the section on scalar value constructors. MeowChow s aamecha.s a..a\u$&owag.print	[reply]

Just to add, it isn't working because everything is taken literally in double quotes. So, this means that you have to backslash everything that you want to show up (`</tr>` should be `<\/tr>`). There are many other ways to print stuff like that. You can use here documents, qq, q, or just use a similarly long statement something like...: `print "<TR><TD>hi hi hi hi",'</tr></tD>';` [download] Note that variation of quotes there. This will work as expected and print out the `</tr></td>` as you expected, without the Perl interpreter's interaction. UPDATE: I now look at it and think I am wrong. But, I do now that you can always print HTML the right way, with CGI.pm, of course :-). Other than that I do not know what is wrong... Tiptoeing up to a Perl hacker.

Hmm...my HTML seems to come out funny when I put a / in there. Tiptoeing up to a Perl hacker. Dave AKA damian	[reply]

There are also modules to take care of this kind of thing. Take a look at this node where I give sample code for creating a form and table. Generating your code programattically guarantees that you don't miss any closing tags, and that your HTML is structured properly. It's worth a look, and it makes stuff much easier to maintain, and easier to see the page logic. xoxo, Andy %_=split/;/,".;;n;u;e;ot;t;her;c; ". # Andy Lester 'Perl ;@; a;a;j;m;er;y;t;p;n;d;s;o;'. # http://petdance.com "hack";print map delete$_{$_},split//,q< andy@petdance.com >	[reply]
