python - Selenium 没有通过链接文本找到元素

Question

我尝试使用 driver.find_element_by_partial_link_text('2019')但我收到一条错误消息，说它无法找到该元素。我还尝试使用 find_element_by_link_text('') 并使用整行，但它不起作用。想法？

driver.find_element_by_partial_link_text('2019').click()

这就是我一直在尝试但没有任何效果的方法。这是网页 HTML:

Answer 1

在您的示例 HTML 中，“2019”的唯一实例位于 <h2> 中。标记，而不是 anchor ( <a> ) 链接。自 find_element_by_partial_link_text()只搜索 anchor 标签，它不会找到它。

您可以通过 XPath 进行搜索，通过部分文本查找任意 元素。像这样:

all_matches = driver.find_elements_by_xpath("//*[text()[contains(., '2019')]]")
all_matches[0].click()

XPath 说:

1. 搜索所有 元素 ( * )
2. 查看每个项目的 text()反过来
3. 如果text() contains()字符串“2019”，将其添加到匹配集中。

当然，我们只点击匹配的第一个元素。
