如何在php中获取xml节点的属性值？

I'm using simplexml to read a xml file. So far i'm unable to get the attribute value i'm looking for. this is my code.

          if(file_exists($xmlfile)){
              $doc = new DOMDocument();
              $doc->load($xmlfile);
              $usergroup = $doc->getElementsByTagName( "preset" );
              foreach($usergroup as $group){         
                 $pname = $group->getElementsByTagName( "name" );
                 $att = 'code';
                 $name = $pname->attributes()->$att; //not working

                 $name = $pname->getAttribute('code'); //not working
                 if($name==$preset_name){
                     echo($name);
                      $group->parentNode->removeChild($group);
                 }
              }
          }

and my xml file looks like

<presets>
<preset>
 <name code="default">Default</name>
  <createdBy>named</createdBy>
  <icons>somethignhere</icons>
 </preset>
</presets>

我正在使用simplexml来读取xml文件。 到目前为止，我无法获得我正在寻找的属性值。 这是我的代码。 

  if（file_exists（$ xmlfile））{
 $ doc = new DOMDocument（）; 
 $ doc-＆gt; load（$ xmlfile）  ; 
 $ usergroup = $ doc-＆gt; getElementsByTagName（“preset”）; 
 foreach（$ usergroup as $ group）{
 $ pname = $ group-＆gt; getElementsByTagName（“name”）; 
 $ att  ='code'; 
 $ name = $ pname-＆gt; attributes（） - ＆gt; $ att;  //不工作
 
 $ name = $ pname-＆gt; getAttribute（'code'）;  //不工作
 if（$ name == $ preset_name）{
 echo（$ name）; 
 $ group-＆gt; parentNode-＆gt; removeChild（$ group）; 
} 
} 
} 
}  
   
 
 
我的xml文件看起来像 
 
 
 ＆lt; presets＆gt; 
＆lt; preset＆gt; 
＆lt;  name code =“default”＆gt;默认＆lt; / name＆gt; 
＆lt; createdBy＆gt;名为＆lt; / createdBy＆gt; 
＆lt; icons＆gt; somethignhere＆lt; / icons＆gt; 
＆lt; / preset＆gt; 
＆lt; / presets＆gt;

    Actually question in my head includes deleting a node as well , mistakenly i could not add it. So in my point of view this is the complete answer, i a case if someone else find this useful. This answer doesn't include SimpleXMLElement class because how hard i tried it didn't delete the node with unset(); . So back to where i was , i finally found an answer. This is my code. and its Simple!!!

    if(file_exists($xmlfile)){
              $doc = new DOMDocument();
              $doc->load($xmlfile);
              $presetgroup = $doc->getElementsByTagName( "preset" );
              foreach($presetgroup as $group){       
                 $pname = $group->getElementsByTagName( "name" );
                  $pcode = $pname->item(0)->getAttribute('code');
                 if($pcode==$preset_name){
                      echo($preset_name);
                      $group->parentNode->removeChild($group);
                 }
              }
          }
        $doc->save($xmlfile);
