Get Iframe Src content using Selenium Python

Question

I have added to an html file: maintenance.html an iframe:

<iframe name="iframe_name" src="maintenance_state.txt" frameborder="0" height="40" allowtransparency="allowtransparency" width="800" align="middle" ></iframe>

And I want to get the content of the src file maintenance_state.txt using Python and Selenium. I'm locating the iframe element using:

maintain = driver.find_element_by_name("iframe_name")

However maintain.text is returning an empty value. How can I get the text written in maintenance_state.txt file.

Thanks for your help.

Answer 1

As some sites' scripts stop the iframe from working properly if it's loaded as the main document, it's also worth knowing how to read the iframe's source without needing to issue a separate driver.get for its URL:

driver.switch_to.frame(driver.find_element_by_name("iframe_name"))
print(driver.page_source)
driver.switch_to.default_content()

The last line is needed only if you want to be able to do something else with the page afterwards.
