how to find parent element that has specific child using By.xpath()?

Question

Recently i've been scrapping by using selenium-webdriver in nodejs for a few days. so i have to find element has specific child element but i don't know how find it.

i have used following operator but it doesn't work

By.xPath("tr[contains(@class, 'datetime2')]")

following html

<table>
  <tbody>
    <tr style="bacrgound-color:#eee">
      <td class="datetime2">
        20:00
      </td>
    <tr>
    
    <tr></tr>
    
    <tr style="bacrgound-color:#eee">
      <td class="datetime2">
        21:00
      </td>
    <tr>
    
    <tr style="bacrgound-color:#eee">
      <td class="datetime2">
        22:00
      </td>
    <tr>
    
    <tr></tr>
  </tbody>
</table>
