------解决方案--------------------
这个主要涉及到xml DOM的操作吧,去看看这方面的内容吧。
------解决方案--------------------
用 xml DOM
------解决方案--------------------
if ( file_exists ( 'out.xml' )) {<br />     $xml  = simplexml_load_file ( 'out.xml' );<br /> <br />     foreach ($xml->pic->list as $key => $value) {<br />      	$attr = (array) $value->attributes ();<br />      	var_dump($attr[[email&#160;protected]']['smallinfo']);<br />      } <br />} else {<br />    exit( 'Failed to open test.xml.' );<br />}

这个只能取到里面的值 想改里面的值建议去下个simple_html_dom或者phpQuery
