html=etree.HTML(text)
ul=html.xpath("//ul[@class='lists']")[0]
lis = ul.xpath("//li")


for li in lis:
 try:
    title=li.xpath("@data-title")[0]

    duration=li.xpath("@data-duration")[0]
    region=li.xpath("@data-region")[0]
    director=li.xpath("@data-director")[0]
    actors=li.xpath("@data-actors")[0]
    thumbnail=li.xpath(".//img/@src")[0]
    movie={
