如何通过Selenium在iframe中检索html

selenium selenium-webdriver iframe

如何通过Selenium在iframe中检索html,selenium,selenium-webdriver,iframe,webdriverwait,Selenium,Selenium Webdriver,Iframe,Webdriverwait,如果html如下所示，我希望在iframe标记下获取所有html内容（示例中为all xxxx）： <body> <div></div> .... <div class = A> <div class=B> <div class = C> <iframe class = D> xxxxxxx </iframe> </div>

如果html如下所示，我希望在iframe标记下获取所有html内容（示例中为all xxxx）：

<body>

      </iframe>
    </div>

我试过这样的代码，这个代码有什么问题吗？错误消息是：

错误消息：

Unable to find element with xpath

对于这样的HTML：

<html>
<head>
<title>
Stack over flow
</title>
</head>
<body>
<p>This ius </p>
<iframe class='D'></iframe>

<p><a href="https://www.w3schools.com" target="iframe_a">W3Schools.com</a></p>  

<html>
<head>
<title>
Stack over flow iframe
</title>
</head>

<body>  
<p>This is 1 </p>

<p>This is 2 </p>

<p>This is 3 </p>

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC 
from selenium.webdriver.common.action_chains import ActionChains

driver   = webdriver.Chrome(executable_path = r'C:/Users/abhishep/Downloads/chromedriver_win32/chromedriver.exe')
driver.maximize_window()

wait = WebDriverWait(driver,40)

driver.get("C:\\Users\\User***\\Desktop\\Python+Selenium\\SO.html")  

wait.until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe.D")))

print(driver.page_source)
source = driver.execute_script("return document.body.innerHTML;")
print(source)

根据您在尝试获取

标记下的所有HTML内容时提供的HTML，逻辑上，

中应该有一些您希望与之交互的元素。因此，首先您必须诱导WebDriverWait使框架可用并切换到它，然后再次诱导WebDriverWait使所需元素可见（可交互），然后您可以按如下方式提取整个源代码：

#WebDriverWait for the desired frame to be available and switch to it
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@class='D']")))
#WebDriverWait for the desired element to be visible
WebDriverWait(driver, 10).until(EC.visibilityOfElementLocated((By.XPATH, "xpath_of_desired_element")))
print(driver.page_source)

注意：您必须添加以下导入：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

你需要先切换到框架，然后把所有元素都放进去，这样有帮助吗？

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
