Ruby Selenium无法获取h4标记的值

我无法在selenium ruby代码中获取

标记的值

这是我的选择器config.yml

selectors:
  - Topix_Header_Div:
    - selector: ".local-news"
    - type: 'css'
    - element: 'div'
  - Topix_Header_Div:
    - selector: ".local-news .comp-header"
    - type: 'css'
    - element: 'div'
  - Topix_Header_Heading:
    - selector: ".local-news .comp-header h4"
    - type: 'css'
    - element: 'heading'

标记位于嵌套的div中，如下所示

<div class="local-news">
 <div class="comp-header">
  <h4>Local News - Buffalo, NY</h4>
 </div>
</div>

这是我得到的输出
