如何在xml标记名称php中获取单词？

Question

我有这个xml文件https://pastebin.com/2PFthem2

我想获取所有讲座的“教室”属性以将其打印为HTML数组

example Classroom =“ B3”我想要B3

到目前为止的代码

x=atomic_pre_increment(&a)-1; y=atomic_pre_increment(&a);

}

Answer 1

您需要使用getAttribute()方法，

$lectures = $event->getElementsByTagName( "Lecture" );

$classRoomArray = [];

foreach($lectures as $lecture) {
   // getting Classroom attribute of each leature element
   $classRoom = $lecture->getAttribute('Classroom');

   //push to classroom array
   array_push($classRoomArray, $classRoom);

}


echo $classRoomArray; // will print all classroom attribute of all lecture element
