I'm trying to crawl the titles of all tables from this URL: https://www.nature.com/articles/s41586-023-06192-4

I can find this HTML element on the website:

<b id="Tab1" data-test="table-caption">Table 1 Calculated Ct–M–Ct angles</b>

I cannot crawl this title because it cannot be found. Even if I print the HTML script to the console, this element cannot be found.

I use the following code to print the HTML script:

from requests_html import HTMLSession
from bs4 import BeautifulSoup

url = 'https://www.nature.com/articles/s41586-023-06192-4'

session = HTMLSession()
response = session.get(url)

response.html.render()

soup = BeautifulSoup(response.html.raw_html.decode('utf-8'), 'html.parser')
print(soup.prettify())

Use BeautifulSoup’s crawling function:

def get_tables(driver):
    tables = []
    html = driver.page_source
    soup = BeautifulSoup(html, 'html.parser')

    for i in range(1, 11):
        try:
            table_caption = soup.find('b', {'id': f'Tab{i}', 'data-test': 'table-caption'})
            table_text = table_caption.text if table_caption else "Not Available"
            if table_text != "Not Available":
                print(f"找到表格{i}：{table_text}")
            else:
                print(f"未找到表格{i}。")
            tables.append(table_text)
        except Exception as e:
            print(f"处理表格{i}时出错：{str(e)}")
            tables.append("Not Available")

    return tables

Use Selenium’s crawling function:

def get_tables(driver):
    tables = []

    for i in range(1, 11):
        try:
            table_caption = driver.find_element_by_css_selector(f'b#Tab{i}[data-test="table-caption"]')
            table_text = table_caption.text if table_caption else "Not Available"
            if table_text != "Not Available":
                print(f"找到表格{i}：{table_text}")
            else:
                print(f"未找到表格{i}。")
            tables.append(table_text)
        except Exception as e:
            print(f"处理表格{i}时出错：{str(e)}")
            tables.append("Not Available")

    return tables

I try to use Selenium and BeautifulSoup to crawl the website. I've checked the iframe. I delayed the fetch operation for 40 seconds to ensure the page loaded completely. Even GPT4 cannot solve this problem.
