还有就是上面是print_r输出的内容，而var_dump输出的是这样的

PHP 5.6.22 通过。

<code>$xml_string = '<?xml version="1.0" encoding="utf-8"?>

libxml_disable_entity_loader(true);
$obj = simplexml_load_string($xml_string, 'SimpleXMLElement', LIBXML_NOCDATA);

print_r($obj);

echo $obj->attributes()->DeliveryNo;</code>

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 StateDate="2016-06-29 12:32:13" StateMessage="亲，您的包裹已安排极速转运！" StateOperator="PH002JP" />
        <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 StateDate="2016-07-04 09:32:16" StateMessage="亲，您的包裹已清关完毕！" StateOperator="PH006CN" />
    </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>
