用漂亮的湯從 html 字符串中提取文本

Question

我編寫以下代碼從網頁中提取價格：

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)

output 是：

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

我想提取 1,384 個值。

Answer 1

嘗試這個

document.getElementById("ctl00_phContents_ctlHeader_lblPrice").innerText

或者，如果您有動態元素，則可以遍歷每個元素並從中獲取 innerText。

Answer 2

您可以使用.text屬性來獲取所需的文本。

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

印刷：

1,384
