Устранение неполадок выражения XPath для выбора узлов на основе дочернего узла

NB. Этот вопрос очень похож на другой, который я попросил - выражение Xpath для выбора узлов на основе наличия дочернего узла? - Тем не менее, я пытаюсь расширить его и провалиться.

У меня есть страница с листингом HTML.

Я пытаюсь использовать Xpath для различения доступных и проданных продуктов.

Доступные продукты выглядят следующим образом:

<div class="product-widget-container">

Я думал, что смогу продолжить либо "распроданный" класс, либо текст " Sold Out внутри него.

Я пробовал все из следующего, и никто из них, похоже, не работает - все они дают мне полный набор продуктов:

//div[@class="product-widget-container" and not(div[@class="stock-status be_sprites sold-out"])]

//div[@class="product-widget-container" and not(div[contains(@class, "sold-out")])]

//div[@class="product-widget-container" and not(div[contains(., "Sold Out")])]

Любые мысли о том, что я делаю неправильно в своем выражении XPath?
