在PHP中，你可以在PHP

使用的DOMDocument

http://php.net/manual/en/class.domdocument.php

例如：

<?php 
    $handle = fopen("1.xml", "rb"); 
    $xml= ''; 
    while (!feof($handle)) { 
     $xml .= fread($handle, 8192); 
    } 
    fclose($handle); 

    $dom = new DOMDocument; 
    $dom->loadXML($xml); 
    $books = $dom->getElementsByTagName('book'); 
    foreach ($books as $book) { 
     echo $book->nodeValue, PHP_EOL; 
    } 
    ?>

我使用的文件，而不是字符串。你能否告诉我其他方式来做到这一点？ – Alpa 2013-02-12 05:34:04

@Alpa你可以使用fopen和fread从file.see中创建一个字符串。更改答案 – 2013-02-12 05:38:08

@mohammadmohsenipur你不需要构建$ xml字符串，你可以简单地使用'$ doc-> load（'1.xml'）; – 2013-02-12 05:40:25

这里有一个简单的解决方案，你可以工作：

<?php 
//Load xml file and than json encode/decode it into an array. 
$a = json_decode(json_encode((array) simplexml_load_file('path_to_your_xml.xml'),1); 

//Loop the array creating a return array 
$return = array(); 
foreach($a['ALL_VERSIONS']['version'] as $key=>$value){ 
    $return[$key]['code'] = $value['@attributes']['code']; 
    $return[$key]['name'] = $value['@attributes']['name']; 

    if(is_array($value['RELEASES_LIST']['release']) && isset($value['RELEASES_LIST']['release'][0]['BRAND_LIST']['BRAND']['@attributes']['code'])){ 
     //Loop sup versions 
     foreach($value['RELEASES_LIST']['release'] as $key2=>$sub){ 
      $return[$key][$key2]['RELEASES_LIST'] = array(
              'core'=>$sub['@attributes']['code'], 
              'name'=>$sub['@attributes']['name']); 
      $return[$key][$key2]['BRAND_LIST'] = array(
              'brand'=>$sub['BRAND_LIST']['BRAND']['@attributes']['code'], 
              'brand_name'=>$sub['BRAND_LIST']['BRAND']['@attributes']['name']); 
     } 

    }else{ 
    $return[$key]['RELEASES_LIST'] = array(
              'core'=>$value['RELEASES_LIST']['release']['@attributes']['code'], 
              'name'=>$value['RELEASES_LIST']['release']['@attributes']['name']); 
    $return[$key]['BRAND_LIST'] = array(
              'brand'=>$value['RELEASES_LIST']['release']['BRAND_LIST']['BRAND']['@attributes']['code'], 
              'brand_name'=>$value['RELEASES_LIST']['release']['BRAND_LIST']['BRAND']['@attributes']['name']); 
    } 
} 

print_r($return);

$xml = simplexml_load_file("data.xml"); 

foreach($xml->ALL_VERSIONS->version as $child) 
{ 

    echo "Version code : ".$child['code']; 
    echo "Version name : ".$child['name']; 

    foreach($child->RELEASES_LIST->release as $releaseChild)
