How to get all childs of a node using php xpath?

Question

In the code below:

<tbody>
  <tr class='even'>
    <th>header 1</th>
    <td>11</td>
    <td>12</td>
  </tr>
  <tr class='even'>
    <th>header 2</th>
    <td>21</td>
    <td>22</td>
  </tr>
</tbody>

When I run, $xpath->query("//tr[@class='even']")

It only shows me the contents of the <th> tags. Shouldn't I be getting the contents of the <td> as well i.e. everything inside the <tr> tags?

If not how can I get the td without having to write separate ones like this:

$xpath->query("//tr[@class='even']/th")
$xpath->query("//tr[@class='even']/td")

Answer 1

You can use * selector that select any tag.

$xpath->query("//tr[@class='even']/*")

The above code select every child of tr.even. Also you can use | (OR) operator like bottom code.

$xpath->query("//tr[@class='even']/td | //tr[@class='even']/th");
