<div style='display:none'><?php echo $html;?></div>

//parsing begins here:

       }
    }

 }

echo "Title: $title". '<br/><br/>';
//echo "Description: $description". '<br/><br/>';
$items = $doc->getElementsByTagName('img');

for ($i = 0; $i < $items->length; $i++) {

            $newid = $hi;
            ?>
            <img src="<?php echo $bye; ?>" />
            <input type="hidden" id="myid" value="<?php echo $hi ?>" />

            <?php 

            break;
        }
// var_dump($items->item($i));
}
?>
<style type="text/css">

    #imgFetch img{
        border: 1px solid grey;
        padding: 3px;
        border-radius:10px;
    }
</style>
<script type="text/javascript" src="jquery-1.7.1.min.js"></script>
<script type="text/javascript">
setTimeout(function(){ 

    var myval = $('#myid').val();
    if(myval !== undefined )
    var elem = $('#'+myval).get(0).outerHTML;
    var ogImg = $('#ogImg').val();
    if(ogImg !== undefined ){
        src = ogImg;
    }else{
    var src =  document.getElementById(myval).src;
    }
    $('body').append('<div id="imgFetch"><img  src="'+src+'" /></div>');
    $('#imgFetch img').css('width','150px');
    $('#imgFetch img').css('height','130px');

    }, 0000);


</script>

what i am doing here is getting whole HTML in $html and echo also I am getting image object by using getElementByTagName function, I have got the image correctly and it works on any website url.But the problem is, I am not sure that how can i target price and size given with that image.I wants to grab whole ul element or select element if the price and size are in select element.So please tell me if there is any workaround.
