Parsing HTML Table - PHP

I am trying to parse many HTML tables, with the URLs stored in the database. The current problem with my code is that it will fail on a different table every time. Here is the part of the code that gets the error:

while ($sqlrow = mysqli_fetch_row($res)) {
echo "Started Processing Table " . $tables . PHP_EOL;
$tables++;
$data = file_get_contents($sqlrow[1]);
$dom->loadHTML($data);
$dom->preserveWhiteSpace = false;
$teamtable               = $dom->getElementById("reTeamTable");
$teamrows                = $teamtable->getElementsByTagName('tr');

The lines that usually fails is either the "getElementById" command or the "getElementsByTagName" command. The error I am getting is: "PHP Fatal error: Call to a member function getElementsByTagName() on a non-object in /scouting/teamlist.php on line 20". I don't understand why this is getting an error on a different URL every time.

Its means that $dom doesnt find element with id="reTeamTable" ( $teamtable is null ). Before call getElementsByTagName , check $teamtable on empty.
