PHP遍历指定文件夹内的XML文件，100分啊，100分。

<?xml version="1.0" encoding="UTF-8"?><template><title><![CDATA[《克鲁德一家》预告]]></title>   <image>130112001.jpg</image>   <intro><![CDATA[《克鲁德一家》预告]]></intro>   <mediapath>130112001.3gp</mediapath></template>

指定文件夹目录路径：D:
@3（此文件夹下有多个XML文件）遍历开始（读取4个XML文件，满足后停止遍历）读取一个XML文件内容$title=XML内的title$img=XML内的image$path=此XML文件的路径把这3个变量输出到页面遍历结束

$doc = new DOMDocument();$doc->load ("a.xml");$tmp =  $doc->getElementsByTagName('template');foreach($tmp as $t){	Echo 'title:'.$t->getElementsByTagName('title')->item(0)->nodeValue."<br>";	Echo 'image:'.$t->getElementsByTagName('image')->item(0)->nodeValue."<br>";	Echo 'intro:'.$t->getElementsByTagName('intro')->item(0)->nodeValue."<br>";	Echo 'mediapath:'.$t->getElementsByTagName('mediapath')->item(0)->nodeValue."<br>";}

$i == 0foreach (glob("D:\001\1003\*.xml") as $filename) {    if ($i >3) break;    读取$filename……    $i++;}

$dir='D:
@3';function readxml($dir,&$arr){	if($handle=opendir($dir)){		while(false!==($file=readdir($handle))){			$sub_dir=$dir.DIRECTORY_SEPARATOR.$file;			if(is_dir($sub_dir)&&$file!='.'&&$file!='..'){				readxml($sub_dir,$arr);			}elseif(preg_match('/.xml$/',$file)){				if(count($arr)>3){					return false;				}				$arr[]=$sub_dir;			}		}	}}readxml($dir,$arr);foreach($arr as $x){	$doc = new DOMDocument();	$doc->load ($x);	$tmp =  $doc->getElementsByTagName('template');	foreach($tmp as $t){		Echo 'title:'.$t->getElementsByTagName('title')->item(0)->nodeValue."<br>";		Echo 'image:'.$t->getElementsByTagName('image')->item(0)->nodeValue."<br>";		Echo 'intro:'.$t->getElementsByTagName('intro')->item(0)->nodeValue."<br>";		Echo 'mediapath:'.$t->getElementsByTagName('mediapath')->item(0)->nodeValue."<br>";	}	Echo "<p>--------------------------------------</p>
