How to divide a string into several results with RegEx? - Eisbahn - 2010-06-04

Hello again ;=)

from the website I only get a list of genres for a movie, which need to be divided. HTML source is as following:

Code:
<div class="info">

<h5>Genre:</h5>

<div class="info-content">

Action | Abenteuer | Fantasy | Sci-Fi

</div>

</div>

With the RegEx

Code:
<RegExp input="$$1" output="&lt;genre&gt;\1&lt;/genre&gt;&lt;genre&gt;\2&lt;/genre&gt;&lt;genre&gt;\3&lt;/genre&gt;&lt;genre&gt;\4&lt;/genre&gt;" dest="5+">

    <expression>Genre:&lt;/h5&gt;\n&lt;div class="info-content"&gt;\n([^|\n]+)[ \| ]?([^|\n]*)[ \| ]?([^|\n]*)[ \| ]?([^|\n]*)</expression>

</RegExp>

I get all the four genres. But what about movies with just one, two, three genre? I will get (min) one empty genre :=(
Any chance to surpress this fault?

Regards,

Eisbahn
