PHP XML data missing custom attribute data -

i have custom xml of following format:

<xml>     <data>         <node index='0.04, 0.17, 0.30, 0.43, 1.48, 2.01, 4.23, 4.36'>             node data#1         </node>         <node index='0.07, 0.20, 0.33, 0.46, 1.51, 2.04, 4.27, 4.40'>             node data#2         </node>         <node index='0.11, 0.24, 0.37, 0.50, 1.55, 2.08, 4.30, 4.43'>             node data#3         </node>     </data> </xml> 

i'm using following simple php code read xml file:

$file = 'test1.xml';     if(file_exists($file) ){         print "xml file found!";         $xml = file_get_contents($file) or die('<br>error loading xml file');         $xml = simplexml_load_string($xml) or die('<br>error loading xml file');     }else{         print "no xml file found!";     }      if($xml){         print "<pre>";         print_r($xml);         print "</pre>";     } 

the output code shows simplexmlelement object xml output expected except index attributes data source xml missing. output looks following:

[data] => simplexmlelement object (     [node] => array         (             [0] =>                  node data#1             [1] =>                  node data#2             [2] =>                  node data#3         ) ) 

it's missing node index attributes data.

no, it's not inside print_r() can access them, not missing:

$xml_string = <<<xml <xml>     <data>         <node index='0.04, 0.17, 0.30, 0.43, 1.48, 2.01, 4.23, 4.36'>             node data#1         </node>         <node index='0.07, 0.20, 0.33, 0.46, 1.51, 2.04, 4.27, 4.40'>             node data#2         </node>         <node index='0.11, 0.24, 0.37, 0.50, 1.55, 2.08, 4.30, 4.43'>             node data#3         </node>     </data> </xml> xml;  $xml = simplexml_load_string($xml_string);  $first_node = $xml->data->node[0]; $attrs = (string) $first_node->attributes()->index; echo $attrs; 

or of course of want loop each node:

$xml = simplexml_load_string($xml_string); $nodes = $xml->data->node; foreach($nodes $node) {     echo (string) $node . '<br/>';     $attrs = (string) $node->attributes()->index;     echo $attrs . '<br/>';     $numbers = explode(', ', $attrs);     print_r($numbers);     echo '<hr/>'; } 

sample output
