Substitute a phrase and characters from a result with simple html dom

[SEOGuy]

My code working good to result me an external part of the price of the item from an online store, but is loaded with standard html, css and letters, I wanna be just numbers without "," or "ABC" just numbers like "123". This is a part of external mobile-store site: \[code\]<div class="prod-box-separation" style="padding-left:15px;padding-right:15px;text-align:center;padding-top:7px;"> <div style="color:#cc1515;"> <div class="price-box"> <span class="regular-price" id="product-price-47488"> <span > <span class="price">2.443,⁰⁰ RON</span> </span> </span> </div> </div></div><div class="prod-box-separation" style="padding-left:10px;padding-right:10px;"> <style> .delivery { display:block; } </style> <p class="availability in-stock"> <div class="stock_info">Produs in stoc</div> <div class="delivery"><div class="delivery_title">Livrare(in timpul orelor de program):</div> <div class="delivery_item">Bucuresti - BANEASA : imediat</div> <div class="delivery_item">Bucuresti - EROILOR : luni dupa ora 13.00.</div> <div class="delivery_item">CURIER : Marti</div> </div> </p>\[/code\] Garan?ie: 12 luni Here is my actual code:\[code\]<?phpinclude_once('../simple_html_dom.php');$dom = file_get_html("http://www.site.com/page.html");// alternatively use str_get_html($html) if you have the html string already...foreach ($dom->find('span[class=price]') as $node){echo $node->innertext;} ?> \[/code\]and my result is this: \[code\]2.443,⁰⁰ RON\[/code\] But correct result will be: \[code\]2.443\[/code\] or \[code\]2443\[/code\]
