元素内部＆LT;跨度＆GT;标签找不到回来了美丽的汤 [英] Element inside <span> tag not found back with Beautiful Soup

问题描述

我已经用美丽的汤与Python从网站抓取数据的尝试。

I have tried using Beautiful Soup with Python to crawl data from a website.

当我检查网站本身我看到以下内容：

When I inspect the website itself I see the following:

"<span id="test"> 567 </span>"

但是当我用美丽的汤，我看到的是：

but when I use Beautiful soup, all I see is:

"<span id="test"></span>"

这是因为如果该号码已被隐藏的安全和保护的目的，但我怎样才能从这个分析的信息？我认为这是一个动态的JS元素，但我不知道肯定，以及如何访问它。

It is as if the number has been hidden for security and protection purposes but how can I get this info from parsing? I think it is a dynamic JS element but I don’t know for sure and how to access it.

推荐答案

下面是一个例子code实现它：

Here is an example code to implement it:

import scrapy
from selenium import webdriver
from bs4 import BeautifulSoup as bs

class SomeSpider(scrapy.Spider):
    name = "some"
    allowed_domains = ["yourdomain.com"]

    def __init__(self, *a, **kw):
        super(SomeSpider, self).__init__(*a, **kw)
        self.start_urls = ['http://www.yoururl.com',]
        firefox_profile = webdriver.FirefoxProfile()
        self.driver = webdriver.Firefox(firefox_profile=firefox_profile) 


   def parse(self, response):
       self.driver.get(response.url)
       page = TextResponse(response.url, body=self.driver.page_source, encoding='utf-8')  

      #HERE whatever you want do do eg. text = page.xpath('//span[@id="test"]').extract_first()
