php - Retrieving Node Values from XML if it have 1 diff child name and rest are equal -

i had xml file this

 <report>     <table>       <columns>          <column name="datetime"/>          <column name="userlogin"/>          <column name="campaignname"/>          <column name="adgroupname"/>          <column name="changes"/>       </columns>       <row datetime="aug 13, 2013 11:56:34 pm" userlogin="hello123" campaignname="search exact parts - 2012 usa" adgroupname="12 volt razor battery" changes="text ad changed  status changed enabled paused"/>       <row datetime="aug 13, 2013 11:56:34 pm" userlogin="hello123" campaignname="search exact parts - 2012 usa" adgroupname="razor quad battery" changes="text ad changed status changed enabled paused"/>       <row datetime="aug 13, 2013 11:56:34 pm" userlogin="hello123" campaignname="search exact parts - 2012 usa" adgroupname="razor quad tires" changes="text ad changed status changed enabled paused"/>       <row datetime="aug 13, 2013 11:56:34 pm" userlogin="hello123" campaignname="search exact parts - 2012 usa" adgroupname="razor replacement battery" changes="text ad changed status changed enabled paused"/>       <row datetime="aug 13, 2013 11:56:34 pm" userlogin="hello123" campaignname="search exact parts - 2012 usa" adgroupname="razor.com" changes="text ad changed status changed enabled paused"/>     </table>   </report> 

my problem i'm trying read xml file. code wrote is,

foreach($xml->children() $secgen=>$value){         foreach($value->columns->children() $thrgen){             $feilds[] = $thrgen['name'];         }     $data[] = $value->row['datetime']; } 

this code reading first row value ie.," aug 13, 2013 11:56:34 pm "

even tried in possible ways know. cannot retrieve ways in correct way. if 1 can solve problem, thankful.

use xpath select datetime attribute of <row> nodes:

$results = $xml->xpath("//row/@datetime"); 

see them all:

foreach ($results $result) echo "$result <br />";
