DOM解析器foreach [英] DOM Parser Foreach

问题描述

有没有人知道为什么这不行？

Does anyone know why this wouldn't work?

foreach($html->find('tbody.result') as $article) {
    // get retail
    $item['Retail'] = trim($article->find('span.price', 0)->plaintext);
    // get soldby
    $item['SoldBy'] = trim($article->find('img', 0)->getAttribute('alt'));

    $articles[] = $item;
}
print_r($articles);

推荐答案

尝试这样：

$html = file_get_html('http://www.amazon.com/gp/offer-listing/B002UYSHMM');

$articles = array();

foreach($html->find('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)) $item['SoldBy'] = $article->find('img', 0)->getAttribute('alt');
    $articles[] = $item;
  }

}

print_r($articles);
