PHP的SimpleXML遍历所有属性

一 代码

<?php
header("Content-Type:text/html;charset=utf-8");					//设置编码
/*  创建XML格式的字符串  */
$str = <<<XML
<?xml version='1.0' encoding='gb2312'?>
<object name='commodity'>
	<book type='computerbook'>
		<bookname name='PHP从入门到精通'/>
	</book>
	<book type='historybook'>
		<booknanme name='上下五千年'/>
	</book>
</object>
XML;
$xml = simplexml_load_string($str);							//创建一个simplexml对象
foreach($xml->children() as $layer_one){							//循环子节点元素
	foreach($layer_one->attributes() as $name => $vl){				//输出各个节点的属性和值
		echo $name.'::'.$vl;
	}
	echo '<br>';
	foreach($layer_one->children() as $layer_two){					//输出第二层节点元素
		foreach($layer_two->attributes() as $nm => $vl){			//输出各个节点的属性和值
			echo $nm."::".$vl;
		}
		echo '<br>';
	}
}
?>

 

二 运行结果

type::computerbook
name::PHP从入门到精通
type::historybook
name::上下五千年
