Question

我是PHP和XML的新手。我试图从我认为是XML文件的子元素中提取特定元素。

主要课程为<events>，<event>课程中有多个<events>。我试图从XML文件中提取特定数据并显示它们。

<?php
$xml = simplexml_load_file('http://xml.pinnaclesports.com/pinnaclefeed.aspx?sporttype=Football&sportsubtype=nfl');
foreach($xml->children() as $event){
    echo $event->participants->participant->participant_name . ", ";
    echo $event->participants->participant[1]->participant_name . ", ";
    echo $event->periods->period->spread->spread_visiting . ", ";
    echo $event->periods->period->total->over_adjust . "<br>";
}
?>

这是输出，没有PHP error_log条目：

我感谢任何帮助。

要访问嵌套元素，您只需遵循从上下文元素（event）开始到目标元素的元素路径。如果正确格式化XML，将更容易看到路径/层次结构：

foreach($xml->children() as $event) {
    echo $event->participants->participant->participant_name . ", ";
    echo $event->participants->participant[1]->participant_name . ", ";
    echo $event->periods->period->spread->spread_visiting . ", ";
    echo $event->periods->period->total->over_adjust . "<br>";
}
