How can I interact with the ddlDelegacion (dropdown menu) element in this webpage using selenium webdriver for python?
I´m doing this to periodically download some (periodically updated) documents from a government webpage for my family
The HTML code is this
<div id="divFrame" style="display:block">
<iframe id="ifrPaginaSecundaria" style="width:985px;height:330px;" frameborder="0" src="Registro/Web/wfrAcceso.aspx">
#document == $0
<html xmlns="http://www.w3.org/1999/xhtml"><head id="Head1"><title>
ACCESO

</body></html>
</iframe>
</div>
My approach is this:
driver.switch_to_frame("ifrPaginaSecundaria")
delegacion=driver.find_element(By.XPATH,"/html/body/table/tbody/tr[2]/td/table/tbody/tr[2]/td[3]")
delegacion.elect_by_index(36)
However it raises this exception:
AttributeError Traceback (most recent call last)
~\AppData\Local\Temp/ipykernel_9740/553253340.py in <module>
15 pass
16 #frame=driver.find_element(By.XPATH,'//*[@id="divFrame"]')
---> 17 driver.switch_to_frame("ifrPaginaSecundaria")
18 delegacion=driver.find_element(By.XPATH,"/html/body/table/tbody/tr[2]/td/table/tbody/tr[2]/td[3]")
19 delegacion.elect_by_index(36)
AttributeError: 'WebDriver' object has no attribute 'switch_to_frame'
If i don´t use the driver.switch_to_frame it throws this exception despite the element being both present and visible:
NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"/html/body/table/tbody/tr[2]/td/table/tbody/tr[2]/td[3]"}

i´m running Python 3.9.7 and Selenium 4.3.0 and i work with Jupyter Notebooks installed with Anaconda
CodePudding user response：
While I cannot test that page, and the question does not contain full web page html, it is advisable to wait for the iframe to be available before switching to it:
WebDriverWait(browser, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH, "//*[@id='ifrPaginaSecundaria']")))
Is that iframe nested in another iframe, or some shadowroot element? If you manage to successfully switch to it, you should also wait for the elements to load in it. You need the following imports as well:
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

CodePudding user response：
The html-select element is within an <iframe>
Solution
To select the <option> element with index=36 you have to:
Induce WebDriverWait for the desired frame to be available and switch to it.
Induce WebDriverWait for the desired element to be clickable.
You can use either of the following locator strategies:
Using XPATH:
driver.execute("get", {'url': 'http://rh.imss.gob.mx/tarjetonjubilados/(S(4symsfxrnmn3eneitlifwyjy))/default.aspx'}) WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@id='ifrPaginaSecundaria']"))) Select(WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//select[@id='ddlDelegacion']")))).select_by_index(36)
Note : You have to add the following imports :
from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.common.by import By from selenium.webdriver.support import expected_conditions as ECBrowser Snapshot:
