Searching for the #document element using Python with Selenium WebDriver

While working with Python's Selenium Webdriver, I encountered a challenge when trying to access elements within an #document tag using the following HTML code.

I attempted both

driver.find_element_by_xpath("html/body/div[@id='frame']/iframe/*")

and

elem = driver.find_element_by_tag("iframe")

, followed by elem.find_element_by_xpath in order to find inner elements but unfortunately, was unsuccessful.

Another approach I experimented with was using

driver.switch_to_frame(driver.find_element_by_tag("iframe"))

, along with xpath expressions to locate the inner elements, however this method also did not yield any results.

Description of Frame:

<div>
    <iframe>
        #document
            <html>
               <body>
                   <div>
                    ....   
                   </div>
               </body>
            </html>
    </iframe>
</div>

When dealing with iframes, it is important to switch to the iframe and then utilize standard query methods. This method has proven successful in a variety of test scenarios.

Don't forget to switch back to the default content once you have completed your tasks within the iframe.

Now, let's address the issue at hand. How are you populating the iframe? Are you simply creating HTML and saving it to a file or are you referencing an example site? It's possible that the iframe may not contain the expected content. You can try the following approach:

from selenium.webdriver import Firefox

browser = Firefox()
browser.get('localhost:8000') # or wherever the HTML is hosted
iframe = browser.find_element_by_css_selector('iframe')
browser.switch_to_frame(iframe)
print(browser.page_source)

This code snippet will output the HTML content within the iframe. Does it match your expectations or is it mostly empty? If it's empty, consider serving the iframe contents separately.

Many web application developers tend to steer clear of iframes due to various reasons. One common recommendation is to incorporate a 'wait' time using Expected Conditions for smoother execution. This allows you to effectively retrieve values from your tags, which I have referred to as val1 in this case.

from selenium.webdriver.support.ui import WebDriverWait as wait

from selenium.webdriver.support import expected_conditions as EC
.... #some  code
.... #some  code
wait(driver, 60).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,'//*[@id="iframeid"]')))

.... #some code
.... #some code

val1 = wait(browser, 20).until(
EC.presence_of_element_located((By.XPATH,'//tr[(@cid="1")]/td[@ret="2" and @c="21"]')))

I trust that this information proves beneficial!
