使用bs4从JavaScript文本范围中提取数据 [英] Extract data using bs4 from a javascript text span

问题描述

我试图从文本/javascript脚本之后的跨度中提取一些数据，我尝试使用正则表达式将其都变得脆弱: 在text/javascript之后如何获取跨度?

im trying to extract some data from a span that is after a text/javascript script, i tried with regex both its to fragile: how can i get the span after text/javascript?

html_content = urlopen('https://www.icewarehouse.com/Bauer_Vapor_1X/descpage-V1XS7.html')

soup = BeautifulSoup(html_content, "lxml")

price =soup.find(class_='crossout')
span = price('span')
print(span) 

输出不良:

 649.99 949.99

推荐答案

我认为您正在尝试获取数组msrp的最小值和最大值.在这种情况下，您不能使用BS.使用普通格式.

I think you are trying to get the minimum and maximum of the array msrp. In which case you can't use BS for that. Use plain re.

尝试一下:

from urllib.request import urlopen
from bs4 import BeautifulSoup
import re

html_content =urlopen('https://www.icewarehouse.com/Bauer_Vapor_1X/descpage-V1XS7.html')
soup = BeautifulSoup(html_content, "lxml") 
pattern = re.compile("msrp.push\((.*?)\);.*msrp.push\((.*?)\);")
m = pattern.search(soup.text)
if m:
    print(m[1], m[2])

这使用两个捕获组从将值压入数组msrp的行中获取最小值和最大值.

This uses two capturing groups to get the minimum and maximum values from the line where values are pushed into the array msrp.
