I would probably do something like:
my $file;
my %values;
# open the text file and read in all contents (eliminate new lines)
.... #elided for space
# now search
my @patterns( "Pre-paid hours", "Hours used so far",
"Excess hours billed at", ... );
foreach( @patterns ) {
if( $file =~ /$_:\s+\$?(\d+(\.\d+)?)/ ) {
$values{$_} = $1;
}
else {
die "Could not find $_\n";
}
}
What this does is search for the patterns listed in the @pattens array
followed by a colon and spaces an optional $, followed by digits and an
optional fractional part. It then will store the numbers in a hash that is
indexed by the pattern...so you could say
print $values{"Pre-paid hours"};
and it would print
744
