I can't locate this element.. I'm trying to un-check the history box and dl box (they're checked by default)

from selenium import webdriver
import time


chrome_path = r"C:\Users\Skid\Desktop\chromedriver.exe"
driver = webdriver.Chrome(chrome_path)
driver.get("chrome://settings/clearBrowserData")

driver.find_element_by_xpath("""//*[@id=delete-browsing-history-checkbox"]""") #unchecks history
driver.find_element_by_xpath("""//*[@id="delete-download-history-checkbox"]""") #unchecks dl history

This is the page source that someone wanted me to update.

Reset to default

driver.find_element_by_xpath is just looking for the checkbox and returning it as WebElement. You want to click on it to unchecked it

driver.find_element_by_xpath("""//*[@id="delete-browsing-history-checkbox"]""").click()

Also, you forgot apostrophes in the first xpath after @id=. It should be like in the example above.

Edit

You can try locating the checkbox by id

 driver.find_element_by_id("delete-browsing-history-checkbox").click()

Edit 2

The checkbox are inside iframe. You need to switch to it first

driver.switch_to.frame("settings") # switch to the iframe by name attribute
# driver.switch_to.frame(driver.find_element_by_name("settings")) # should also work
driver.find_element_by_id("delete-browsing-history-checkbox").click()
driver.switch_to.default_content() # switch back to main window

Yeah, I've tried that. I shoulda told you that.. here's the error selenium.common.exceptions.InvalidSelectorException: Message: invalid selector: Unable to locate an element with the xpath expression //*[@id=delete-browsing-history-checkbox"] because of the following error: SyntaxError: Failed to execute 'evaluate' on 'Document': The string '//*[@id=delete-browsing-history-checkbox"]' is not a valid XPath expression.
@nobodyskiddy see the edit to my question, I already answered on that :)
I still get an error :( selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"//*[@id="delete-browsing-history-checkbox"]"} (Session info: chrome=48.0.2564.109)
@nobodyskiddy I added another solution.

Can you add to your question what you get as body from selenium?

 driver.get("chrome://settings/clearBrowserData")
 driver.page_source

If I check the source code in Google Chrome of this page I get:

view-source:chrome://chrome/settings/clearBrowserData

<body>

<div id="navigation"><iframe src="chrome://uber-frame/" name="chrome" role="presentation"></iframe></div>

<div class="iframe-container"
    i18n-values="id:historyHost; data-url:historyFrameURL;"
    data-favicon="IDR_HISTORY_FAVICON"></div>
<div class="iframe-container"
    i18n-values="id:extensionsHost; data-url:extensionsFrameURL;"
    data-favicon="IDR_EXTENSIONS_FAVICON"></div>
<div class="iframe-container"
    i18n-values="id:settingsHost; data-url:settingsFrameURL;"
    data-favicon="IDR_SETTINGS_FAVICON"></div>
<div class="iframe-container"
    i18n-values="id:helpHost; data-url:helpFrameURL;"
    data-favicon="IDR_PRODUCT_LOGO_16"></div>

<script src="chrome://chrome/strings.js"></script>
<script src="chrome://resources/js/i18n_template.js"></script>

</body>

It might be necessary to find another way to do it, if your driver cannot see this node.

Edit

In the source code you posted as page_source returned from selenium, there isn't the node you are trying to find.

After doing a find_element_by... all you get is the element. You also need to have a .click() on that element.

Either:

elem = driver.find_element_by_xpath("""//*[@id=delete-browsing-history-checkbox"]""")
elem.click()

or:

driver.find_element_by_xpath("""//*[@id=delete-browsing-history-checkbox"]""").click()

Btw, you could just use find_element_by_id("delete-browsing-history-checkbox") in your case.

Also, I don't think selenium works on non-web pages. So chrome settings and Firefox's about:config pages (for example) don't work with selenium.
