I prefer to match each field separately.
#!perl
use strict;
use warnings;
*FILE_EXPECTED_RESULT = *DATA;
while (<FILE_EXPECTED_RESULT>) {
next if /^\s*$/;
chomp;
print "\n", $_ , "\n";
my (@match) = /
( \w* \. (?: c|cpp|h ) ) # File Namew
\s*
( None | \d{1,2}\.\d\d%\sof\s\d{1,3} ) # Percent 2
\s*
( None | \d{1,2}\.\d\d%\sof\s\d{1,3} ) # Percent 3
/xms;
print "title : " . $match[0] . "\n";
print "percent2 : " . $match[1] . "\n";
print "percent3 : " . $match[2] . "\n";
}
close(FILE_EXPECTED_RESULT);
__DATA__
Title Percent2 Percent3
test1.cpp 0.00% of 21 0.00% of 16
test2.c None 16.53% of 484
test3.h 0.00% of 138 None

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
