my $contents = do { local $/; <DATA> };
while ($contents =~
/
\s* ([^=\s]+) \s* = \s*
(
(?:
(?! \s*
(?:
[^=\s]+ \s* =

$
)
)
.

/xmsg
) {
print("[$1 => $2]\n");
}
__DATA__
name1=value1
name2 = value2
name3 = value3
but wait, there is
more
name4=
value4
Ouputs
[name1 => value1]
[name2 => value2]
[name3 => value3]
[name4 => value4]
Update: The above works by never allowing bad data in the value. The following is an alternate solution that works by starting with an empty value, and extending it as much as possible.
my $contents = do { local $/; <DATA> };
while ($contents =~
/
\s* ([^=\s]+) \s* = \s* (.*?)
# Extend the value.
(?= \s*
(?:
[^=\s]+ \s* =
|
$
)
)
/xmsg
) {
print("[$1 => $2]\n");
}

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).

or How to display code and escape characters
are good places to start.
