Even with your incomplete HTML, Mojo::DOM to the rescue:

#!/usr/bin/perl

use strict;
use warnings;
use Mojo::DOM;
use feature 'say';

my $html = 'Information</div><br><div class="formline"><div class="for
+mlabel">FillDB File Size Limit:</div><div class="forminput">0.0% ( 0 
+/ 3145728 Bytes )</div></div><div class="formline"><div class="formla
+bel">FillDB File Count Limit:</div><div class="forminput">0.0% ( 0 / 
+10000 Files)</div></div><br><hr><div';

my $dom = Mojo::DOM->new( $html );

for my $element ( $dom->find('.forminput')->each ){
  say $element->text;
}

Output:

0.0% ( 0 / 3145728 Bytes )
0.0% ( 0 / 10000 Files)

If you have the file locally, the docs show how to read it in, if you are parsing a live site, you could just combine it all at once using Mojo::UserAgent (for example).

Update: Depending on the full page you may need to alter the selector somewhat. A full example would help.

See Parsing HTML/XML with Regular Expressions: Don't use regexes. I'd recommend Mojo::DOM instead. I've written several examples.

Honestly, the answer to that question depends on your constraints:

• How soon do you need this data?
• Is this a one-off, or will you need to utilize this more than this one time? (As someone's signature here said, "Makeshifts last longest.")
• How complex is your actual data? (Is it just this, or was this a SSCCE?)
• How comfortable do you feel working with a new-to-you module?

A regex is probably the quick-and-dirty way, but is also the most likely to break if the data changes. There are several Tutorials here of modules designed to work with HTML (and several others designed to work with XML, but may also be of use).

Given the time, were it me I would consider looking at those various Tutorials and experimenting with the modules shown there, but as I said, it depends on your criteria.

Hope that helps.

So you only have an HTML fragment to parse from, and not the entire HTML document?

It's easier if you have a well-formed doc.

I have an actual file, I was just providing a fragment of the file

Ok, then almost certainly the easiest approach is a parsing library. Regexes might seem easiest until the input becomes complex in ways not anticipated by the regex. Once you've drilled down to the point in the HTML document you want, using a parsing libary, you can then resort to a regex to pull the appropriate information from the target portion of the document obtained from the parser.

Hi davido,

This is what I need to extract from the html file:

Relay Status Information

FillDB File Size Limit:
0.09% ( 2772 / 3145728 Bytes )
FillDB File Count Limit:
0.01% ( 1 / 10000 Files )

Here is a sample of the html file:

My work environment is very strict so I am very limited in what modules can be installed.

Thanks

I see you have HTML::TreeBuilder installed. This is one way you can use that:

Update: changed slightly to avoid errors

my $tree = HTML::TreeBuilder->new;
$tree->parse_file($file);
$tree->eof;

my @divs = $tree->find_by_attribute('class','formline');
for my $div (@divs) {
    my $label_div = $div->look_down('class','formlabel') or next;
    my $label = $label_div->as_text;
    my $input_div = $div->look_down('class','forminput') or next;
    my $input = $input_div->as_text;
    print "$label $input\n";
}
