Try this simple one, Hope this one will be helpful.

Try this code snippet here

$xml_data = simplexml_load_file('demo.xml');
$result=$xml_data->xpath('//Game[@Date="08/25/2017"]');//querying with XPath
$result=array_slice($result, 0,2);//slicing data for two results
foreach ($result as $game) 
{
    $odds = $game->xpath('SportsBook[@Name="3Dimes"]/Odds');
    $t = $game['Time'];
    echo 'Time: ' . $t . ' LineType: ' . $odds[0]->attributes()['LineType']
      . ' LastUpdated: ' . $odds[0]->attributes()['LastUpdated'] . PHP_EOL;
}

Use the following approach:

$xml_data = simplexml_load_file('demo.xml');

foreach ($xml_data->xpath('//Game[@Date="08/25/2017" and position() <= 3]') as $game) {
    $t = $game['Time'];
    $odds = $game->xpath('SportsBook[@Name="5Dimes"]/Odds');
    echo 'Time: ' . $t . ' LineType: ' . $odds[0]->attributes()['LineType']
        . ' LastUpdated: ' . $odds[0]->attributes()['LastUpdated'] . PHP_EOL;
}

The output:

Time: 1:45 PM LineType: 2 LastUpdated: 10
Time: 1:45 PM LineType: 2 LastUpdated: 10
