11python xpath 是什么鬼？如下代码中有的对，有的不对

其实仔细观察后很简单

datas = html.xpath('//ol[@class="grid_view"]/li')    #这段话绝对了他的根和魂data_title = data.xpath('div/div[2]/div[@class="hd"]/a/span[1]/text()')  #剩下的决定的是在这个根和魂的基础上，它的分支

p_name = data.xpath('div/div[@class="p-name p-name-type-2"]/a/em')
p_price = data.xpath('div/div[@class="p-price"]/strong/i/text()')

p_comment = data.xpath('div/div[@class="p-commit"]/strong/a/text()')

p_img = data.xpath('div/div[@class="p-img"]/a/img/@src')

p_icons = data.xpath('div/div[@class="p-icons"]/ i/text()')

data_title = data.xpath('div/div[2]/div[@class="hd"]/a/span[1]/text()')

data_info = data.xpath('div/div[2]/div[@class="bd"]/p[1]/text()')
data_quote = data.xpath('div/div[2]/div[@class="bd"]/p[2]/span/text()')

data_score = data.xpath('div/div[2]/div[@class="bd"]/div/span[@class="rating_num"]/text()')

 data_num = data.xpath('div/div[2]/div[@class="bd"]/div/span[4]/text()')

data_picurl = data.xpath('div/div[1]/a/img/@src')
