Question

I am trying to pull the price and seller from the amazon offer listing pages found at:

http://www.amazon.com/gp/offer-listing/B002UYSHMM

I can get the price by using:

$ret['Retail'] = $html->find('span[class="price"]', 0)->innertext;

This pulls the first price in the offer listing

I tried to pull the matching seller of the first price by using the below to get the alt value from the img which contains the seller name:

$ret['SoldBy'] = $html->find('ul.sellerInformation img', 0)->getAttribute('alt');

It worked for the first one but as I went down it started missing sellers and even missing prices in some cases.

Can anyone tell why it would miss sellers and even jump around on prices? All I did to get additional sellers is:

$ret['Retail2'] = $html->find('span[class="price"]', 1)->innertext;
$ret['SoldBy2'] = $html->find('ul.sellerInformation img', 1)->getAttribute('alt');
$ret['Retail3'] = $html->find('span[class="price"]', 2)->innertext;
$ret['SoldBy3'] = $html->find('ul.sellerInformation img', 2)->getAttribute('alt');
$ret['Retail4'] = $html->find('span[class="price"]', 3)->innertext;
$ret['SoldBy4'] = $html->find('ul.sellerInformation img', 3)->getAttribute('alt');
$ret['Retail5'] = $html->find('span[class="price"]', 4)->innertext;
$ret['SoldBy5'] = $html->find('ul.sellerInformation img', 4)->getAttribute('alt');
$ret['Retail6'] = $html->find('span[class="price"]', 5)->innertext;
$ret['SoldBy6'] = $html->find('ul.sellerInformation img', 5)->getAttribute('alt');
$ret['Retail7'] = $html->find('span[class="price"]', 6)->innertext;
$ret['SoldBy7'] = $html->find('ul.sellerInformation img', 6)->getAttribute('alt');

Thank you for any suggestions!

I used a foreach and put the results into an array. Worked much better since the number of sellers varies by item.

foreach($html->find('div.resultsset table tbody.result tr') as $article) {  
if($article->find('span.price', 0)) {   
// get retail   
$item['Retail'] = $article->find('span.price', 0)->plaintext;   
// get soldby   
if($article->find('img', 0)->getAttribute('alt') <> '') { 
$item['SoldBy'] = $article->find('img', 0)->getAttribute('alt'); } 
else {$item['SoldBy'] = $article->find('ul.sellerInformation li a b', 0)->plaintext;} 
$ret[] = $item;  
 } 
}
