上面是我要改的xml文件,要修改里的4个的值和smallinfo属性,求大神帮帮忙。


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.' );}

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

$s =<<< XML<?xml version='1.0' encoding='GB2312'?><img List alt="请问怎么在php里修改xml文件?" ><pic><list path="images/01.jpg"   smallpath="images/01.png" smallinfo="黑客的局域网攻击">.html/article/hardware/008.html</list><list path="images/02.jpg"   smallpath="images/02.png" smallinfo="维护你的光驱">http://www.niutuku.com/</list><list path="images/03.jpg" smallpath="images/03.png" smallinfo="数字地球">http://www.niutuku.com/</list><list path="images/04.jpg" smallpath="images/04.png" smallinfo="网络改变生活">http://www.niutuku.com/</list></pic><rollTime fade_in="10">3</rollTime><text font="微软雅黑" size="14" bold="true" color="0xfffffff"></text></imgList>XML;$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();
