问题
I'm trying to get the content under Signers, Counter Signers and X509 Signers from https://www.virustotal.com/gui/file/03d1316407796b32c03f17f819cca5bede2b0504ecdb7ba3b845c1ed618ae934/details
from selenium import webdriver
op = webdriver.ChromeOptions()
op.add_argument('headless')
driver = webdriver.Chrome(executable_path="/Desktop/chromedriver", options=op)
details_url = "https://www.virustotal.com/gui/file/03d1316407796b32c03f17f819cca5bede2b0504ecdb7ba3b845c1ed618ae934/details"
driver.get(details_url)
element = driver.find_element_by_xpath("/html/body/vt-ui-shell")
print(element.text)
The result doesn't include the parts under Signers, Counter Signers and X509 Signers
I also tried to do
driver.find_element_by_xpath("//*[@id="details"]//div/vt-ui-signature-info//vt-ui-expandable/span")
to locate that part, but it ended up giving me
NoSuchElementException: Message: no such element: Unable to locate element
回答1:
The Signers fields e.g. Microsoft Windows are within nested #shadow-root (open).
Solution
To extract the text Microsoft Windows you have to use shadowRoot.querySelector() and you can use the following Locator Strategy:
Code Block:
driver.get('https://www.virustotal.com/gui/file/03d1316407796b32c03f17f819cca5bede2b0504ecdb7ba3b845c1ed618ae934/details') print(driver.execute_script("return document.querySelector('file-view').shadowRoot.querySelector('vt-ui-file-details').shadowRoot.querySelector('vt-ui-signature-info').shadowRoot.querySelector('vt-ui-expandable-detail').shadowRoot.querySelector('slot')").text)
Console Output:
Microsoft Windows

You can find a couple of relevant discussions in:
- Selenium "selenium.common.exceptions.NoSuchElementException" when using Chrome

element=driver.execute_script(
"return document.querySelector('body file-view').shadowRoot.querySelector('vt-ui-file-details').shadowRoot.querySelector('vt-ui-signature-info').shadowRoot.querySelector('vt-ui-expandable').shadowRoot.querySelector('[class=\"details\"]')")
this prints the signature version information , similarly you have to find the rool and call shadowroot and find the element for other roots

Shadow dom is not part of document so you have to use javascript executor to find elements inside it
