Ok, couldn't resist, here's some code (needs Perl version 5.10+ for \K):
c:\@Work\Perl\monks>perl -wMstrict -le
"use 5.010;
;;
use Regexp::Common qw(number);
;;
my @lines = (
qq{Line 1 = 0154.45 +02 13.56 +03 64.35 \n},
qq{Line 2 = +09 23.12 +10 8798 \n},
);
;;
my $prefix = qr{ \G (?: \A Line \s* \d+ \s* =)? \s+ }xms;
for my $line (@lines) {
my @numbers = $line =~ m{ $prefix \K $RE{num}{real} }xmsg;
printf qq{'$_' } for @numbers;
print '';
}
"
'0154.45' '+02' '13.56' '+03' '64.35'
'+09' '23.12' '+10' '8798'
Update: Of course, \K isn't critical to this approach — I just like it so much... The expression
m{ $prefix ($RE{num}{real}) }xmsg
(\K removed, parentheses (...) around the $RE{...} sub-expression) produces identical output for the given input, and I'm not aware of any version incompatibilities.

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).
