need to extract certain values from attribute and place them in variables
<p>In the following markup on a page I want to extract out the following and put them in seperate variables.</p>

<p>1- In the onclick attribute get the value after the "ProductID" and put it in its own variable. "ProductID" 
So in this case it would be 318</p>

<p>2- In the onclick attribute get the value after the "Orig_price" and put it in a variable, "Orig_Price" So in this case it would be 22.95</p>

<p>3- In the onclick attribute get the value after the "width" and put it in a variable, "width" So in this case it would be 330</p>

<p>4- In the onclick attribute get the value after the "height" and put it in a variable, "height" So in this case it would be 300</p>

<pre><code>&lt;a href="javascript:void(0);" onclick="window.open('/BulkDiscounts.asp?ProductID=318&amp;ProductCode=' + escape('LB30X40ES') + '&amp;Orig_Price=22.95', 'Discounts', 'scrollbars,status,resizable,width=330,height=300');"&gt;&lt;img src="/v/vspfiles/templates/100/images/buttons/btn_quantitydiscounts.gif" border="0" align="absmiddle"&gt;&lt;/a&gt;
</code></pre>
