How to get Production Co: on Company Credits?

<h3 class="subheading">Company Credits</h3>
<div class="txt-block">
    <h4 class="inline">Production Co:</h4>
    <span itemprop="creator">
        <a href="company" itemprop='url'><span class="itemprop" itemprop="name">Inflatable Film</span></a>
    </span>,
    <span itemprop="creator">
        <a href="company" itemprop='url'><span class="itemprop" itemprop="name">True Productions</span></a>
    </span>
        <a href="companycredits?ref_=tt_dt_co" itemprop='url'>See more</a>&nbsp;&raquo;
    </span>
</div>

I'm trying to use this code but it's not working:

$arr['production_co'] = $this->match('/Production Co:<\/h4>.*?<div class="info-content">(.*?)(<a|<\/div)/ms', $html, 1);

Please help me to get Production Co.
