php怎么取取xml里的数据？
<?xml version='1.0' encoding='gb2312'?>
<imgList>
<pic>
<list path="/Public/images/01.jpg" smallpath="/Public/images/01.png" smallinfo="管理创造价值">http://www.china-lz.org/</list>
<list path="/Public/images/02.jpg" smallpath="/Public/images/02.png" smallinfo="价值、合作、专业、实践">http://www.china-lz.org/</list>
<list path="/Public/images/03.jpg" smallpath="/Public/images/03.png" smallinfo="七彩虹显卡十周年庆典">http://www.china-lz.org/</list>
<list path="/Public/images/04.swf" smallpath="/Public/images/04.png" smallinfo="Colorful S101">http://www.china-lz.org/</list>
</pic>

<rollTime fade_in="10">6</rollTime>
<text font="微软雅黑" size="14" bold="true" color="0xfffffff"></text>
</imgList>

我想取<list path="/Public/images/01.jpg" smallpath="/Public/images/01.png" smallinfo="管理创造价值">http://www.china-lz.org/</list>里面path,smallinfo,url
放到数组里，我用$xml = simplexml_load_file（'file.xml'），foreach $xml->pic 取不出来。

------解决方案--------------------
DOM解法：

PHP code

$doc = new DomDocument();
$doc->load("file.xml"); 
$lists=$doc->getElementsByTagName("list");
foreach($lists as $list){
      $path=$list->getAttribute("path"); 
      $smallinfo=$list->getAttribute("smallinfo"); 
     $arr[]=array('path'=>$path,'smallinfo'=>$smallinfo,'url'=>$list->nodeValue);
}
print_r($arr);
