PHP trying to retieve a tricky value using XQuery with wildcard

[max_maggot]

I am trying to retrieve a really tricky array of values. The value I am trying to retrieve are the

-price values and the text within the price tag

-color values which can be more than one option (black and white in this case)

<dd>
<div class="input-box">
  <select name="options[1216]" id="select_1216" 
   class="product-custom-option" title=""  onchange="opConfig.reloadPrice()">
   <option value="" >-- Please Select --</option>
   <option value="4185"  price="4.99" >4GB +$4.99</option>
   <option value="4186"  price="5.99" >8GB +$5.99</option>
   <option value="4187"  price="9.99" >16GB +$9.99</option>
   <option value="4188"  price="16.99" >32GB +$16.99</option>
   <option value="4189"  price="29.99" >64GB +$29.99</option>
  </select>            
</div>
</dd>
            
<dt>
<label class="required"><em>*</em>Color</label></dt>
<dd class="last">
    <div class="input-box">
        <ul id="options-1215-list" class="options-list">
          <li><input type="radio" class="radio  
               validate-one-required-by-name product-custom-option" 
               onclick="opConfig.reloadPrice()" name="options[1215]" 
               id="options_1215_2" value="4183"  price="0" />

               <span class="label"><label for="options_1215_2">Black </label></span>
               <script type="text/javascript">
          </li>
          <li>
              <input type="radio" class="radio  
               validate-one-required-by-name product-custom-option" 
               onclick="opConfig.reloadPrice()" name="options[1215]" 
               id="options_1215_3" value="4184"  price="0" />
              <span class="label"><label for="options_1215_3">White </label></span>              
          </li>
        </ul>                                    
</div>

I have wrtten the following code to try and retrieve the values of the price but to no avail. I'm trying to use a wildcard character in the xquery to try because other pages will have different option names. Here is what I came up with so far. There won't be more than 20 options on a page. Any help would be much appreciated. Thanks in advance.

$option_array = array();
      for($k = 1; $k <= 20; $k++) {
           $option_array[$k] = $xpath->query("//div[@class='input-box']//select/*/option[$k]/@price")->item(0)->textContent;
           //If we have captured all the images then we need to exit the for loop
           if($option_array[$k] == null){
                 break;
           }
      }

I wouldn't use a for loop. Better to foreach loop over the elements returned from the xpath query, example

$option_array = array();
// finds all <option price="xxx">zzz</option> tags in <div class="input-box">
foreach($xpath->query("//div[@class='input-box']//option[@price]") as $option)
{
    // add price attribute value and and option tag text items to array
    $option_array[] = array($option->getAttribute('price'), $option->nodeValue);
}
