php - Show only the first object with SimpleXMLElement -

this question exact duplicate of:

• selecting children of first result using xpath 1 answer

after extracting data file in php xpath.

my code:

$xml = simplexml_load_file("ccv.xml");      foreach ($xml->xpath('./section[@label="education"]/section[@label="degrees"]') $details) {             foreach ($details->field $f) {             $a = $f->attributes();                 if ('degree type'== $a['label']){                     $x = $f->lov;                     var_dump($x);                     break;                 }             }     } 

the result looks this

object(simplexmlelement)[10]   public '@attributes' =>      array (size=1)       'id' => string '00000000000000000000000000000073' (length=32)   public 0 => string 'doctorate' (length=9) object(simplexmlelement)[9]   public '@attributes' =>      array (size=1)       'id' => string '00000000000000000000000000000072' (length=32)   public 0 => string 'master's thesis' (length=15) object(simplexmlelement)[8]   public '@attributes' =>      array (size=1)       'id' => string '00000000000000000000000000000084' (length=32)   public 0 => string 'bachelor's equivalent' (length=21)  

how can return first object doctorate.

in xpath can wrap initial query within ()[1] xpath query return first match :

(xpath/query/that/may/return/multiple/result)[1] 

for particular case should :

(./section[@label="education"]/section[@label="degrees"])[1]
