I have a big Hash list, the some of the keys are made up of the combination of regular expression pattern. For example :
%cat = (
'C[AEIOU]NWAY' => 'AAA',
'(BOSTON|CHICAGO)' => 'BBB',
'(LAS VEGAS|NEVADA)' => 'CCC'
'(DALLAS|AUSTIN)' => 'DDD'
'(NASHVILLE|M[AEIOU]MPHIS)' => 'EEE'
);
I would like to search the KEYS and compare to a $variable, and print the VALUE for the matched $variable.
For example, if the $variable = 'CHICAGO', then I would like to pull the corresponding value which is 'BBB'.
Could anyone give me some idea or suggestion?
Thank you...
William

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).
