python - selenium 按包含的标题查找元素？

Question

我需要使用 selenium 从下面的输出中找到 RSSI(4G 信号强度)。

据我所知，我是否首先需要找到包含标题 EE000000 的所有元素。然后我可以看到父 div 中的路径属性与具有相同路径的另一个子 div 匹配

例如0-7262-12686-13379在两个div中命名，一个是标题，另一个是我想要的值。

然后我需要获取以“4G 信号强度”开头的标题来获取该值，我的最终结果应该是

EE100000 -96
EE100001 -81

等等……

到目前为止，我的路径尝试未能按照下面的方法找到 EE100000 值，它试图找到一个现有的 EE 不，不是所有的 EE 不是

driver.find_element_by_xpath('//*[contains(@title, "EE100205")')
SyntaxError: Failed to execute 'evaluate' on 'Document': The string '//*[contains(@title, "EE100205")' is not a valid XPath expression.

我通过以下方式将源添加为图像

下面的源代码示例:-

            <div class="slick-cell lr c0 treeColumn children00">

Answer 1

对于标题以“4G 信号质量”开头的元素的 CSS 选择器:

driver.find_element_by_css_selector("[title^='4G Signal quality']")

，或包含“4G信号质量”:

driver.find_element_by_css_selector("[title*='4G Signal quality']")
