    Let us illustrate several possible methods on this example
    Code:
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
    <html>
    <head>
    <meta http-equiv="content-type" content="text/html; charset=windows-1250">
    <meta name="generator" content="PSPad editor, www.pspad.com">
    <title></title>
    <style type="text/css">
    </style>
    </head>
    <body>
    <div id="pge">
       <p>Somme product...
          <span style="color: red;">Your Price</span>:$ 123,000.07 
          <br>
          Other developments...
       </p>
    </div>
    <script type="text/javascript">
    var texte=document.getElementById('pge').innerHTML;
    var texteAfterYourPrice=texte.substr(texte.indexOf('Your Price')+'your Price'.length);
       alert("After Your Price : \n"+texteAfterYourPrice);
    var texteAfterYourPriceWithoutSpanNor$=texteAfterYourPrice.replace(/^[^>]+>:\$/,'');
       alert("Without Span nor $\n"+texteAfterYourPriceWithoutSpanNor$);
    var texteAfterYourPriceWithoutSpanNor$BeforBr=texteAfterYourPriceWithoutSpanNor$.replace(/<br ?\/?>(.|\n)+$/i,'');
       alert("Texte between ... \n"+texteAfterYourPriceWithoutSpanNor$BeforBr);
    var price=parseFloat(texteAfterYourPriceWithoutSpanNor$BeforBr.replace(/(\s|,)+/g,''));//a Flot or an Integer (parseInt) Without blanks or commas
       alert("The naked Price \n"+price);
    </script>
    </body>
    </html>

    The code I wrote:
    Code:
    <html>
    <head>
    <meta http-equiv="content-type" content="text/html; charset=utf-8">
    <title></title>
    <style type="text/css">
    .TL { font-family:AbakuTLSymSans, sans-serif; font-size:46px; color:gold;} 
    #kiraz { font-family:Verdana; font-size:36px;  color:turquoise;}
    </style>
    <script type="text/javascript">
    // http://www.webdeveloper.com/forum/showthread.php?t=261703
    
    function fiyatlar() {
    var el = document.getElementById('kiraz');
    el.innerHTML = " 2.5"
    }
    </script>
    </head>
    <body>
    <span style="color: red;">Kiraz : </span>
    <span class="TL">&#168;</span>
    <span id="kiraz"></span>
    <br>
    
    <input type="button" value="1 kilo kiraz, bu hafta ka&#231; lira?"  onclick="fiyatlar()">
    
    </body>
    </html>
