xml转换成数组的有关问题

xml转换成数组的问题
现有如下xml:

XML code

<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--><root><rows><errmsg text=""></errmsg><retvalue text="true"></retvalue></rows><records><productno text="000321"></productno><billno text=""></billno><orderno text="D004410439"></orderno><out_trade_no text="100001"></out_trade_no><plcprem text="0.0"></plcprem><orderprem text="50.0"></orderprem><commision text="0.0"></commision></records>....<root></root></root>

xml深度不确定但每个节点都有text属性，想转换成如下数组，有什么好办法吗

PHP code

<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->Array(    [rows] => Array        (            [errMsg] =>             [retValue] => true        )    [records] => Array        (            [productno] =>000321            [billno] =>            [orderno] =>D004410439            [out_trade_no] => 100001            [plcprem] =>0.0            [orderprem] =>50.0            [commision] =>0.0        )        .....)
