• php simplexml - remove xpath node 4 answers

i have xml looks following:

$data = '<search-params>   <date>2013-05-20</date> </search-params> <results>   <date>2013-05-21 14:31:00</date>   <prices>    <for>     <players>1</players>    </for>    <amount>20</amount>   </prices>   <prices>    <for>     <players>2</players>    </for>    <amount>35</amount>   </prices>   <prices>    <for>     <players>3</players>    </for>    <amount>49.5</amount>   </prices>   <prices>    <for>     <players>4</players>    </for>    <amount>60</amount>   </prices>  </results>  <results>   <date>2013-05-21t14:40:00</date>   <prices>    <for>     <players>1</players>    </for>    <amount>20</amount>   </prices>  </results>'; 

now, want strip out of based on rule.

so, if have <players> child node of 4, should return <results> nodes have value.

is possible in in php?

i can load using simplexml_load_string($data). problem how find information , remove nodes.

thanks

// first, xml must wraped root tag. $data = '<root>     <search-params>         <date>2013-05-20</date>     </search-params>     <results>         <date>2013-05-21 14:31:00</date>         <prices>             <for>                 <players>1</players>             </for>             <amount>20</amount>         </prices>         <prices>             <for>                 <players>2</players>             </for>             <amount>35</amount>         </prices>         <prices>             <for>                 <players>3</players>             </for>             <amount>49.5</amount>         </prices>         <prices>             <for>                 <players>4</players>             </for>             <amount>60</amount>         </prices>     </results>     <results>         <date>2013-05-21t14:40:00</date>         <prices>             <for>                 <players>1</players>             </for>             <amount>20</amount>         </prices>     </results> </root>';  // instancing simplexmlelement within xml(obviously) $xml = new simplexmlelement($data);  // xpath $xpath = $xml->xpath("results[prices/for[contains(players,'4')]]");  /**  * explained xpath:  *      <results>   *          <prices>/<for>  *              contains <players> content equal 4  */  foreach($xpath $node){     // fun echoes <results> node     echo $node->asxml(); }
