Php 通过foreach显示XML数组中的特定值

php xml

Php 通过foreach显示XML数组中的特定值,php,xml,multidimensional-array,Php,Xml,Multidimensional Array,demo.xml $xml = simplexml_load_file('demo.xml'); foreach($xml->Game as $d) { foreach( $d->SportsBook as $sb) { foreach( $sb->Odds as $odds) { // echo $odds['LineType'].' '.$odds['LastUpdated']."<br/>"; } } } 现在更新了我的问题，我只想在游戏日

demo.xml

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

foreach($xml->Game as $d) {

foreach( $d->SportsBook as $sb) {

foreach( $sb->Odds as $odds) {
  //   echo $odds['LineType'].' '.$odds['LastUpdated']."<br/>";

}
} 
}

现在更新了我的问题，我只想在游戏日期为2017年8月25日的情况下获取，加上仅获取2场游戏。如何在每场比赛中显示特定的赔率值。类似于3倍的值。游戏值，每个游戏的值仅为3倍。结果是这样的

时间：下午1:45 线型：3 最近更新：20

提前感谢。

这种方法最困难的是，一旦你找到了“赔率”元素，你就必须使用parent:::*返回以获取时间部分。

这种方法最困难的一点是，一旦你进入“赔率”元素，你就必须使用parent:::*返回以获取时间部分。

使用函数的解决方案：

$xml = simplexml_load_file('t1.xml');

$xpath = $xml->xpath('//SportsBook[@Name="3Dimes"]/Odds');

foreach ($xpath as $odds)   {
    echo 'Time:'.(string)$odds->xpath('parent::*/parent::*/@Time')[0]
            .' LineType:'. $odds["LineType"]
            .' LastUpdated:'.$odds["LastUpdated"]."\n";
}

输出：

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

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

$xml = simplexml_load_file('t1.xml');

    $odds = $game->xpath('SportsBook[@Name="3Dimes"]/Odds');
    echo 'Time: ' . $t . ' LineType: ' . $odds[0]->attributes()['LineType']
          . ' LastUpdated: ' . $odds[0]->attributes()['LastUpdated'] . PHP_EOL;

请参阅：

Xpath表达式允许您使用路径和条件获取部分DOM。在您的情况下，您希望输出带有特定属性的SportsBook元素中的赔率。这在Xpath中相当简单

获取任何SportsBook元素节点 //运动手册使用特定的名称属性值 //SportsBook[@Name=3次] 获取它们的子节点 //SportsBook[@Name=3次]/赔率如果使用DOM，则返回一个DOMNodelist；如果使用SimpleXML，则返回一个数组。时间属性不在赔率节点上，而是在祖先节点上。所以我们用这个轴

获取游戏祖先节点 //祖先：游戏它们的时间属性祖先：：游戏/@时间将第一个最接近的大小写转换为字符串 StringAn祖：：游戏/@时间转换为字符串的最后一步仅适用于DOMXpath:：evaluate。这是一个完整的DOM示例，其他答案已经显示了SimpleXML逻辑

$document = new DOMDocument();
$document->loadXml($xml);
$xpath = new DOMXpath($document);

$expression = '//SportsBook[@Name="3Dimes"]/Odds';
foreach ($xpath->evaluate($expression) as $odds) {
  printf(
    "Time:%s LineType:%d LastUpdated:%d\n",
    $xpath->evaluate('string(ancestor::Game/@Time)', $odds),
    $odds->getAttribute('LineType'),
    $odds->getAttribute('LastUpdated')
  );
}

输出：

Time:1:45 PM LineType:3 LastUpdated:20
Time:1:45 PM LineType:3 LastUpdated:30
