<shandong dn="day">
<city cityX="236" cityY="90" cityname="滨州" />
<city cityX="296" cityY="90" cityname="东营"/>
<city cityX="296" cityY="90" cityname="青岛"/>
</shandong>

如何用php把他读取到数组里面?
给的就这个格式.

高手指点下 给个函数或者解决方法
不想用 explode 一点一点的拆分

$xml = simplexml_load_string(iconv('gbk','utf-8',file_get_contents('1.xml')));
print_r($xml);

SimpleXMLElement Object
(
[@attributes] => Array
(
[dn] => day
)

[city] => Array
(
[0] => SimpleXMLElement Object
(
[@attributes] => Array
(
[cityX] => 236
[cityY] => 90
[cityname] => 滨州
)

)

[1] => SimpleXMLElement Object
(
[@attributes] => Array
(
[cityX] => 296
[cityY] => 90
[cityname] => 东营
)

)

[2] => SimpleXMLElement Object
(
[@attributes] => Array
(
[cityX] => 296
[cityY] => 90
[cityname] => 青岛
