Why am I getting a random string and not the expected output in Beautiful soup in Python?-CodePudding

With the following url and soup, I have the following and I seek to webscrape the Subdivision Information Section. I have copied the html portion for one house below:

house_url = 'https://www.har.com/homedetail/2701-main-st-1910-houston-tx-77002/15331551'
house_response = requests.get(url=house_url, headers=your_header)
house_soup = BeautifulSoup(house_response.text, 'html.parser').find('div', {'class':'pt-2 pb-2 mr-4 pr-md-5 ml-4 pl-md-5'})

However, whenever I use beautifulSoup to get the text such as "Average List Price:$428,844", This is the output I get:

house_soup.find('div',{'id':'subDivisonInfo'}).find('div',{'class':'row'}).findAll('div',{'class':'col-md-4 col-6 mb-4'})[0].getText()

'\n-----------\n-----------\n'

I am not sure why it is returning this string instead of the actual text?

CodePudding user response：

The required data is loaded from external source via AJAX.So you have to use API url instead.

import requests
from bs4 import BeautifulSoup
api_url= 'https://www.har.com/api/getSubdivisionFacts/15331551'
req=requests.get(api_url).text
#print(req)
soup= BeautifulSoup(req,'lxml')
price = soup.select_one('[] > div:-soup-contains("Average List Price")').find_next_sibling('div')
print(price.text)

Output:

$428,844

CodePudding user response：

Because there is a script executed that gets the data when you open the url in the browser. Try performing a get request in python and check the html contents. The initial html does not contain the details you are looking for such as "Average Listing Price".
