现在更新了我的问题我想只在游戏日期=＆＃34; 08/25/2017和＃34;加上只能获得2场比赛。结果将是这样的

时间：下午1:45   线型：2   LASTUPDATED：10

时间：下午1:45   线型：2   LASTUPDATED：10

提前致谢。

Answer 1

试试这个简单的，希望这个会有所帮助。

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;
}

Answer 2

使用以下方法：

$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;
}

输出：

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

从具有特定游戏日期的xml获取值
