如何找到锚标签的元素部分

Question

我对硒完全陌生。请为提出愚蠢或愚蠢的问题而道歉。

我在网站上有以下内容。我感兴趣的是如何使用 selenium + python 获得 data-selectdate 值。获得 data-selectdate 值后，我想将其与我感兴趣的日期进行比较。

非常感谢您的帮助。

注意：我没有用Beautiful soup什么的。

干杯

<table role="grid" tabindex="0" summary="October 2018">

Answer 1

要获取 属性的值 data-selectdate 您可以使用以下解决方案：

elements = driver.find_elements_by_css_selector("table[summary='October 2018'] tbody td[role='gridcell'][headers^='day']>a")
for element in elements:
    print(element.get_attribute("data-selectdate"))

Answer 2

您可以使用 get_attribute api of element class 来读取元素的属性值。

css_locator = "table tr:nth-child(1) > td[headers='dayMonday'] > a"
ele = driver.find_element_by_css_selector(css_locator)
selectdate = ele.get_attribute('data-selectdate')
