如何用美丽的汤搜索字符串

Question

我正在尝试解析以下网址。我想得到这个网站上所有价格的输出。第一项是59英镑。

我检查了元素并发现html如下所示。我认为最好的方法是搜索类'sr_gs_rackrate_total'，或者选择以“Price for”开头的标题。

我怎样才能在美丽的汤中做到这一点？

<strong class="price scarcity_color sr_gs_rackrate_price
 anim_rack_rate  
" title="Price for 1 night £59">
<b>
<span class="sr_gs_rackrate_total">Total: </span>
£59
</b>
</strong>

Answer 1

这是一种方法：

from bs4 import BeautifulSoup
soup = BeautifulSoup(yourhtml)
span = soup.find('span', {'class': 'sr_gs_rackrate_total'})
b = span.parent
b.span.extract()
b.text

如果有超过一个跨度且价格合适，请使用

for span in soup.find_all('span', {'class': 'sr_gs_rackrate_total'}):
  b = span.parent
  b.span.extract()
  print b.text
