如何使用 Selenium Python 查找 Span 文本？

Question

为什么 span 元素文本没有出现在此处附加主要 div 内容我试图查明我的工作在这里但我得到 No element found what's wrong here 如何存储此 Myvalue 元素以便我可以在其上发出单击命令，请原谅我的英语，如果有更好的替代方法，请建议

main_div = driver.find_elements(By.CLASS_NAME, "sub-menu")
# print(main_div)
for i in main_div:
    for span in i.find_element(By.XPATH,'.//span[@class = "leaf_line_item"]'):
        print(span)

下面的 Html 代码取自 main_div

Answer 1

您可以使用 xpath 进行尝试：

main_div = driver.find_elements(By.CLASS_NAME, "sub-menu")
# print(main_div)
for i in main_div:
    for span in i.find_element(By.XPATH,'//span[@class = "leaf_line_item"]//li[@class="fav_line_item"]//span[@class="leaf_line_item"]'):
        print(span.text)
