xml如下：

<?xml version="1.0" encoding="utf-8"?>

<list>

    <item index="0">

        <name a="a0" b="b0"><![CDATA[张三]]></name>

        <site c="c0" d="d0">http://www.hu-rong.com</site>

    </item>

    <item index="1">

        <name a="a1" b="b1"><![CDATA[李四]]></name>

        <site c="c1" d="d1">www.hu-rong.com</site>

    </item>

</list>

转为数据结构如下：

Array
(
    [item] => Array
        (
            [0] => Array
                (
                    [@attributes] => Array
                        (
                            [index] => 0
                        )

                    [name] => Array
                        (
                            [@attributes] => Array
                                (
                                    [a] => a0
                                    [b] => b0
                                )

                        )

                    [site] => http://www.hu-rong.com
                )

            [1] => Array
                (
                    [@attributes] => Array
                        (
                            [index] => 1
                        )

                    [name] => Array
                        (
                            [@attributes] => Array
                                (
                                    [a] => a1
                                    [b] => b1
                                )

                        )

                    [site] => www.hu-rong.com
                )

        )

)

奇怪的是site的属性丢了

php读xml

<?php

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

//print_r(json_decode(json_encode($xml),true));

echo $xml->getName().'节点下有'.$xml->count().'个item<br/>';

foreach($xml as $item){

    $str='';

    $child=$item->children();

    $attributes=$child->attributes();

    $str.='index为'.$item->attributes()->index.'item下有';

    $str.=$child[0]->getName().'(属性'.$attributes[0]->getName().'=>'.$attributes[0].','.$attributes[1]->getName().'=>'.$attributes[1].')和';

    $str.=$child[1]->getName().'节点';

    $str.='其值分别为:'.$item->name.','.$child[1].'<br/>';

    echo $str;

}

结果如下：

index为0item下有name(属性a=>a0,b=>b0)和site节点其值分别为:张三,http://www.hu-rong.com

index为1item下有name(属性a=>a1,b=>b1)和site节点其值分别为:李四,www.hu-rong.com

list节点下有2个item

例2：

<?php

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

//print_r(json_decode(json_encode($xml),true));

$count=$xml->count();

echo $xml->getName().'节点下有'.$count.'个item<br/>';

$i=0;

foreach($xml as $item){

    $str='';

    $child=$item->children()[$i];

    $attributes=$child->attributes();

    $str.='index为'.$item->attributes()->index.'的item下的';

    $str.=$child->getName().'(属性'.$attributes->getName().'=>'.$attributes[0].','.$attributes[1]->getName().'=>'.$attributes[1].')';

    $str.='其值分别为:'.$child.'<br/>';

    echo $str;

    $i++;

}

运行结果：

index为0的item下的name(属性a=>a0,b=>b0)其值分别为:张三

index为1的item下的site(属性c=>c1,d=>d1)其值分别为:www.hu-rong.com

list节点下有2个item
