lxml example

lxml_html

tree = etree.HTML(html)
for block in tree.xpath("//div[@class='product']"):
    img = block.xpath("//img/@src")[0]
    name = block.xpath("//tr[@class='name']")[0].text
    id = block.xpath("//tr[@class='id']")[0].text

Аналогичен
soup = BeautifulSoup(page) # page - скачиваем страницу и отдаем ее
for item in soup.findAll("div", {"class": "product"}):
img = item.find("img")["src"]
name = soup.find("tr", {"class": "name"})
id = soup.find("tr", {"class": "id"})
