  </span>

</div>

我得到的价格是\ u20ac15 \ t \ t \ t \ t \ t \ t 有什么方法可以使用xpath

从这个html中提取15.99

Answer 1

我使用了xpath和Python的组合，所以可能不是你所追求的，尽管这主要用于摆脱添加到“价格”末尾的无关标签。

price = hxs.select('//span[@class="price"]/text()').extract()
pricebit = hxs.select('//span[@class="price"]/sub[@class="price-bit"]/text()').extract()
totalprice = price + price-bit
totalstr = ''.join(totalprice).replace('\t','')

使用scrapy / xpath提取货币值
