Here's a simple, recursive, function to transform XML data into pseudo E4X syntax ie. root.child.value = foobar



<?php

error_reporting(E_ALL);



$xml = new SimpleXMLElement(

'<Patriarch>

   <name>Bill</name>

   <wife>

     <name>Vi</name>

   </wife>

   <son>

     <name>Bill</name>

   </son>

   <daughter>

     <name>Jeri</name>

     <husband>

       <name>Mark</name>

     </husband>

     <son>

       <name>Greg</name>

     </son>

     <son>

       <name>Tim</name>

     </son>     

     <son>

       <name>Mark</name>

     </son>     

     <son>

       <name>Josh</name>

         <wife>

           <name>Kristine</name>

         </wife> 

         <son>

           <name>Blake</name>

         </son>

         <daughter>

           <name>Liah</name>

         </daughter>

     </son>

   </daughter>

</Patriarch>');



RecurseXML($xml);



function RecurseXML($xml,$parent="")

{

   $child_count = 0;

   foreach($xml as $key=>$value)

   {

      $child_count++;     

      if(RecurseXML($value,$parent.".".$key) == 0)  // no childern, aka "leaf node"

      {

         print($parent . "." . (string)$key . " = " . (string)$value . "<BR>\n");        

      }     

   }

   return $child_count;

}



?>



The output....



.name = Bill

.wife.name = Vi

.son.name = Bill

.daughter.name = Jeri

.daughter.husband.name = Mark

.daughter.son.name = Greg

.daughter.son.name = Tim

.daughter.son.name = Mark

.daughter.son.name = Josh

.daughter.son.wife.name = Kristine

.daughter.son.son.name = Blake

.daughter.son.daughter.name = Liah
