Symfony 2 Dom Crawler: how to get text

Question

I want to fetch the text inside last div. I have tried something below as well

$html = $crawler1->filter('span[id="verisysForm:cnicStatusPanel"]')->text();  // returns empty

Here is the structure from where i want to get text.

<span id="verisysForm:cnicStatusPanel">   
   <span style="border: none;background-color: #FFFDFA;">
      <div class="row">
        <div class="col-md-12" style="padding-top: 30px">
            <div style="text-align: left;  border-radius: 10px;background-color: #E9F5DE;background-color: #d9edf7;padding-top:19px;">
                <div style="text-align: left;padding-left: 10px;font-size: 18px;font-family: calibri; color: black;padding-bottom:10px;">
                  The Card: 123456789 and issue date: 1999/10/08 is currently INACTIVE.  However, another card has been issued in lieu of this card.
