<?php 
if($value['name'] == 'scans') 
{ 

      print_r($value->object);

    } 
echo "</ul>";

Answer 1

，你必须使用嵌套foreach：

foreach($xml->object->field as $key => $value) 
{ 
    (...) 
    if($value['name'] == 'scans') 
    { 
     foreach($value->object as $obj) 
     { 
      /* Here you can output <object> attributes */ 
      foreach($obj->field as $field) 
      { 
       /* Here you can output <field> attributes and values */ 
      } 
     } 
    } 
}
