无法在 python 中使用 selenium 网络驱动程序获取文本
Not able to get the text with selenium web driver in python
我正在尝试使用 selenium 网络驱动程序获取文本，这是我的代码。
PYTHON 脚本：
输出为空字符串
text_value=driver.find_element_by_xpath('//*[@id="root"]/div/div/div/div[2]/div/div[3]/div[1]/div[2]/span[2]').text
print(text)
text_value=driver.find_element_by_xpath('//span[2]').text
print(text)
使用 JAVASCRIPT:
输出为 NONE
text_value=driver.find_element_by_xpath('//*[@id="root"]/div/div/div/div[2]/div/div[3]/div[1]/div[2]/span[2]')
value=driver.execute_script('arguments[0]. textContent;',text_value)
print(value)
text_value=driver.find_element_by_xpath('//*[@id="root"]/div/div/div/div[2]/div/div[3]/div[1]/div[2]/span[2]')
value=driver.execute_script('arguments[0]. innerText;',text_value)
print(value)
预期结果是： 1/15

要从 Span 元素获取值，请引入 WebDriverWait 和 visibility_of_element_located() 以及以下 xpath.Try 选项。
使用文本:
print(WebDriverWait(driver,10).until(EC.visibility_of_element_located((By.XPATH,"//span[text()='Question']/following::span[1]"))).text)
或
print(WebDriverWait(driver,10).until(EC.visibility_of_element_located((By.XPATH,"//span[contains(.,'Question')]/following::span[1]"))).text)
使用属性 innerHTML:
print(WebDriverWait(driver,10).until(EC.visibility_of_element_located((By.XPATH,"//span[contains(.,'Question')]/following::span[1]"))).get_attribute("innerHTML"))
使用属性 textContent:
print(WebDriverWait(driver,10).until(EC.visibility_of_element_located((By.XPATH,"//span[contains(.,'Question')]/following::span[1]"))).get_attribute("textContent"))
你需要下面的导入来执行上面的代码。
