【问题描述】:
我有以下代码来抓取页面,https://www.hotukdeals.com
from bs4 import BeautifulSoup
import requests
url="https://www.hotukdeals.com/hot"
r = requests.get(url)
soup = BeautifulSoup(r.text,"html.parser")
deals = soup.find_all("article")
for deal in deals:
priceElement = deal.find("span",{"class":"thread-price"})
try:
print(priceElement,priceElement.text)
except AttributeError:
pass
由于某种原因,这有效,在循环中抓取交易价格一定次数,然后停止工作。
程序输出:
<span class="thread-price text--b cept-tp size--all-l size--fromW3-xl">£9.09</span> £9.09
<span class="thread-price text--b cept-tp size--all-l size--fromW3-xl">£39.95</span> £39.95
<span class="thread-price text--b cept-tp size--all-l size--fromW3-xl">£424.98</span> £424.98
<span class="thread-price text--b cept-tp size--all-l size--fromW3-xl">£8.10</span> £8.10

<span class="thread-price text--b cept-tp size--all-l size--fromW3-xl">£2.50</span>
<span class="thread-price text--b cept-tp size--all-l size--fromW3-xl text--color-greyShade">£20</span>
<span class="thread-price text--b cept-tp size--all-l size--fromW3-xl">£19</span>

<span class="thread-price text--b cept-tp size--all-l size--fromW3-xl text--color-greyShade">£49.97</span>
<span class="thread-price text--b cept-tp size--all-l size--fromW3-xl">FREE</span>
<span class="thread-price text--b cept-tp size--all-l size--fromW3-xl">£2.49</span>
<span class="thread-price text--b cept-tp size--all-l size--fromW3-xl">£1.99</span>
<span class="thread-price text--b cept-tp size--all-l size--fromW3-xl">£54.99</span>
<span class="thread-price text--b cept-tp size--all-l size--fromW3-xl">£12.85</span>
<span class="thread-price text--b cept-tp size--all-l size--fromW3-xl">£1.99</span>
<span class="thread-price text--b cept-tp size--all-l size--fromW3-xl">£21.03</span>
<span class="thread-price text--b cept-tp size--all-l size--fromW3-xl">£5.29</span>
从输出中可以看出,在前四行之后,.text 属性为空,但元素中有文本。
有人知道吗?有什么想法或解决方案吗?
