I already said, I want to capture and validate in one pass
You've said it, but you've never said why. If you want to ask a question, don't be shocked by the answer. If you're doing it to learn, fair enough. But realize that most every other programmer would use split for it's succinctness. Moreover, I subscribe to the "every function can be explained by one sentence not using the word 'and'". You are trying to capture and validate. When something breaks, you've more debugging to do as you're trying to do two things at once.

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).
