用漂亮的汤从html字符串中提取文本

Question

我编写以下代码从网页中提取价格：

from urllib.request import urlopen
from bs4 import BeautifulSoup
url = "https://www.teleborsa.it/azioni/intesa-sanpaolo-isp-it0000072618-SVQwMDAwMDcyNjE4"
html = urlopen(url)
soup = BeautifulSoup(html,'lxml')
prize = soup.select('.h-price')
print(prize)

输出为：

<span class="h-price fc0" id="ctl00_phContents_ctlHeader_lblPrice">1,384</span>

我想提取1,384个值。

Answer 1

尝试一下

document.getElementById("ctl00_phContents_ctlHeader_lblPrice").innerText

或者，如果您具有动态元素，则可以遍历每个元素并从中获取innerText。

Answer 2

您可以使用.text属性来获取所需的文本。

例如：

from urllib.request import urlopen
from bs4 import BeautifulSoup
url = "https://www.teleborsa.it/azioni/intesa-sanpaolo-isp-it0000072618-SVQwMDAwMDcyNjE4"
html = urlopen(url)
soup = BeautifulSoup(html,'lxml')
prize = soup.select_one('.h-price') # <- change to .select_one() to get only one element
print(prize.text)                   # <- use the .text property to get text of the tag

打印：

1,384
