如何使用Selenium和Python在innerText包含前导和尾随空格字符时定位和单击元素

Question

I want to locate (and click) the "Reoni" element, but I do not know what function to use it for

I tried with

driver.find_element_by_class_name("oe_menu_leaf")  

and

driver.find_element_by_class_name("oe_menu_text")

but then selenium raise an error element cant be located, and I tried

driver.find_element_by_link_text("Reoni")

This is the element I want to locate:

<a href="/web#menu_id=86&amp;action=99" class="oe_menu_leaf" data-menu="86" data-action-model="ir.actions.act_window" data-action-id="99">
    <span class="oe_menu_text">
    Reoni
    </span>
</a>

and full html:

If I was not clear enough or if you needed my code, please let me know.

Answer 1

Try something like this:

Clicking the button

From Chrome :

Right click "inspect" on the item you are trying to find the xpath.

Right click on the highlighted area on the console.

Go to Copy xpath

selectElem=browser.find_element_by_xpath('x-path-here').click()

Reading Values Only

from bs4 import BeautifulSoup

innerHTML = browser.execute_script("return document.body.innerHTML")
soup = BeautifulSoup(str(innerHTML.encode('utf-8').strip()), 'lxml')
value = soup.find('span', attrs={'class':'fxst-calendarpro fxst-table-s1'}).text

Answer 2

As the desired element is a dynamic element you need to induce WebDriverWait for the desired element to be clickable and you can use either of the following solutions:

• Using CSS_SELECTOR :

   WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a.oe_menu_leaf[href*='/web#menu_id=']>span.oe_menu_text"))).click()

• Using XPATH and text() :

   WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@class='oe_menu_leaf' and starts-with(@href,'/web#menu_id=')]/span[@class='oe_menu_text' and text()='Reoni']"))).click()

• Using XPATH and normalize-space() :

   WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@class='oe_menu_leaf' and contains(@href,'/web#menu_id=')]/span[@class='oe_menu_text' and normalize-space()='Reoni']"))).click()

• 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 EC
