请问怎么在php里修改xml文件？

回复讨论(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。

用 xml DOM

if ( file_exists ( 'out.xml' )) {     $xml  = simplexml_load_file ( 'out.xml' );      foreach ($xml->pic->list as $key => $value) {      	$attr = (array) $value->attributes ();      	var_dump($attr['@attributes']['smallinfo']);      } } else {    exit( 'Failed to open test.xml.' );}

$s =<<< XML.html/article/hardware/008.htmlhttp://www.niutuku.com/http://www.niutuku.com/http://www.niutuku.com/3XML;$xml = simplexml_load_string($s);for($i=0; $ipic->list); $i++) {  $xml->pic->list[$i] = $i;  $t = $xml->pic->list[$i]->attributes();  $t['smallpath'] = $i;}echo $xml->asXML();
