php解决xml代码

使用simpleXML处理XML











 // 使用simpleXML处理XML

 $xml = simplexml_load_file('./simple.xml');
 //var_dump($xml);
 //echo $xml->getName();
 //var_dump($xml->children());
 $record = '';
 foreach ($xml->children() as $child)
 {
  $record .= '

';
  foreach ($child->children() as $item)
  {

   $record .= '';
  }
  $record .= '';
 }
 echo $record;
?>

'. $child->attributes(). ''. $item .'


将XML转换为数组结构

 代码如下 复制代码

private function change_simple_xml_to_array($obj){
  $i = 0;
  //从根节点下的二层子节点开始遍历
  foreach($obj->children() as $value){
    //如果发生同级、同标签名的情况,则加一维数组;
    if(isset($last_name) && $value->getName()==$last_name){
      //出现同名发现第二个,则推入第二维数组;
      if($i==1) $arr[$last_name]=array($arr[$last_name]);
      //遍历子节点;
      array_push($arr[$last_name],$this->change_simple_xml_to_array($value));
    }else{
      $last_name = $value->getName();
      if(count($value->children())==0) $arr[$last_name] = $value."";
      else $arr[$last_name] = $this->change_simple_xml_to_array($value);
    }
    $i++;
  }
  return $arr;
}
