PHP 5.6.22 通过。

PHP处理XML有几种方式,DOM、XMLReader/Writer、XSL,建议你用后两种,DOM相对耗内存。

<code><?php $a = <<<EOF
<?xml version="1.0" encoding="utf-8"?>
<order deliveryno="PH00127495JP">
    <status>
        <state statedate="2016-06-28 11:37:47" statemessage="亲,您的包裹已入库完成,祝您海淘愉快!" stateoperator="PH002JP"></state>
        <state statedate="2016-06-29 12:32:13" statemessage="亲,您的包裹已安排极速转运!" stateoperator="PH002JP"></state>
        <state statedate="2016-07-02 09:16:58" statemessage="亲,您的包裹已到达HK分拨中心,等待清关中!" stateoperator="PH005CN"></state>
        <state statedate="2016-07-04 09:32:16" statemessage="亲,您的包裹已清关完毕!" stateoperator="PH006CN"></state>
    </status>
</order>
EOF;
$xml = simplexml_load_string($a);
$json = json_encode($xml);
$array = json_decode($json,TRUE);
$states = $array['Status']['State'];
foreach($states as $state) {
    echo $state['@attributes']['StateMessage'],' 操作员:',$state['@attributes']['StateOperator'],',',$state['@attributes']['StateDate'],PHP_EOL;
}
</code>

输出如下:

<code>亲,您的包裹已入库完成,祝您海淘愉快! 操作员:PH002JP,2016-06-28 11:37:47
亲,您的包裹已安排极速转运! 操作员:PH002JP,2016-06-29 12:32:13
亲,您的包裹已到达HK分拨中心,等待清关中! 操作员:PH005CN,2016-07-02 09:16:58
亲,您的包裹已清关完毕! 操作员:PH006CN,2016-07-04 09:32:16</code>
