Simple Dom Parser or CURL TABLE PARSING - php

Question

I need help to get the data from a table. It's an internet usage table and the html code is down below :
<table width="572" border="0" align="center" cellspacing="0">
<tbody><tr valign="top">
<td width="1" class="bgsidelines"></td>
<td width="*" class="bgbottom">
<table summary="" width="100%" border="0" cellpadding="0">
<tbody><tr>
<td width="10" rowspan="2" bgcolor="#CCCCCC"></td>
<td width="443">
<table width="443" height="10" border="0" align="center" cellpadding="8">
<tbody>
<tr>
<td width="100%" class="path"><b>Internet usage</b></td>
</tr>
<tr>
<td class="reg"><!-- Begin yours codes -->
<table width="100%" cellpadding="0" cellspacing="0" border="0">
<tbody><tr>
<table cellpadding="5" cellspacing="1" border="0">
<tbody>
<tr>
<td width="43" bgcolor="#EEEEEE" class="grey"><b><center>MB</center></b>
</td>
<td width="44" bgcolor="#EEEEEE" class="grey"><b><center>GB</center></b>
</td>
<td width="44" bgcolor="#EEEEEE" class="grey"><b><center>MB</center></b>

<td width="44" bgcolor="#EEEEEE" class="grey"><b><center>GB</center></b>

<tr>
<td bgcolor="#FFFFFF" class="reg" nowrap="nowrap">2017-06-01 to<br>2017-
06-18</td>
<td bgcolor="#FFFFFF" align="right" valign="top" class="reg">54815.06</td>
<td bgcolor="#FFFFFF" align="right" valign="top" class="reg">53.53</td>
<td bgcolor="#FFFFFF" align="right" valign="top" class="reg">52114.59</td>
<td bgcolor="#FFFFFF" align="right" valign="top" class="reg">50.89</td>
<td bgcolor="#FFFFFF" align="right" valign="top" class="reg">106929.65</td>
<td bgcolor="#FFFFFF" align="right" valign="top" class="reg">104.42</td>

I've done it in a way that works but only works sometimes, this must be due to the user agent. and it fetches the entire table while I would like each separated values for the internet usage, the ones in the td class="reg" (54815.06, 53.53..) It's hard because there is a table in table.. Also it's
My PHP :
require_once 'advanced_html_dom.php';
$numvl = $_POST['numvl'];
$url =
'https://extranet.videotron.com/services/secur/extranet/tpia/Usage.do?
compteInternet='.$numvl;
$html = new AdvancedHtmlDom();
$html->load_file($url);
$element = $html->find("tr");
echo $element[1]->innertext;

no need for some external lib (advanced_html_dom.php? never heard of), just use PHP's DOMDocument and DOMXPath.
example:
<?php
declare(strict_types=1);
$domd=#DOMDocument::loadHTML(getHTML());
$xpath=new DOMXPath($domd);
foreach($xpath->query("//td[#valign='top' and #class='reg']") as $ele){
var_dump($ele->textContent);
}
function getHTML():string{
$html=<<<'HTML'
<table width="572" border="0" align="center" cellspacing="0">
<tbody><tr valign="top">
<td width="1" class="bgsidelines"></td>
<td width="*" class="bgbottom">
<table summary="" width="100%" border="0" cellpadding="0">

<td width="10" rowspan="2" bgcolor="#CCCCCC"></td>

</tr>
<tr>

</td>

HTML;
return $html;
}
output:
string(8) "54815.06"
string(5) "53.53"
string(8) "52114.59"
string(5) "50.89"
string(9) "106929.65"
string(6) "104.42"
