Untuk mengambil semua data diantara tag < tr> dan < /tr>, gunakan script dibawah ini parsing-tabel.php

<?php
// parsing-tabel.php
$fileHTML = file_get_contents('/tmp/tabel.html');
 
// ambil semua data diantara <tr> dan </tr>
preg_match_all("'<tr>(.*?)</tr>'si",$fileHTML, $ketemu);
 
// cek array data
// var_dump($ketemu);
 
// $ketemu[0] atau array pertama masih memiliki tag <tr> </tr>
// makanya kita memilih $ketemu[1] dari hasil var_dump($ketemu) diatas.
foreach ($ketemu[1] as $data) {
    echo $data;
}

kegunaan tiap baris dari script diatas bisa dilihat di script diatas.
Output script diatas :

    <th>name</th>
    <th>email</th>
    <th>address</th>
    <th>country</th>
 
    <td>Vivien Buckner</td>
    <td>[email protected]</td>
    <td>7575 Pharetra Rd.</td>
    <td>Eritrea</td>
 
    <td>Derek Sharpe</td>
    <td>[email protected]</td>
    <td>7545 Lobortis. Road</td>
    <td>Bangladesh</td>
 
    <td>Bradley Dalton</td>
    <td>[email protected]</td>
    <td>Ap #544-8283 Malesuada Av.</td>
