Here's a slightly modified function that transforms xml data into an associative array with the
indices's into the array have the following syntax, parent.child etc.
So for
<meal>
<type>Lunch</type>
<time>12:30</time>
<menu>
<entree>salad</entree>
<maincourse>steak</maincourse>
</menu>
</meal>
The array would look like this...
array(4) {
["type"]=>
string(5) "Lunch"
["time"]=>
string(5) "12:30"
["menu.entree"]=>
string(5) "salad"
["menu.maincourse"]=>
string(5) "steak"
}
Here's an example
<?php
$xml = new SimpleXMLElement(
'<meal>
<type>Lunch</type>
<time>12:30</time>
<menu>
<entree>salad</entree>
<maincourse>steak</maincourse>
</menu>
</meal>');
$vals = array();
RecurseXML($xml,$vals);
foreach($vals as $key=>$value)
print("{$key} = {$value}<BR>\n");
function RecurseXML($xml,&$vals,$parent="")
{
$child_count = 0;
foreach($xml as $key=>$value)
{
$child_count++;
$k = ($parent == "") ? (string)$key : $parent . "." . (string)$key;
if(RecurseXML($value,$vals,$k) == 0) // no childern, aka "leaf node"
$vals[$k] = (string)$value;
}
return $child_count;
}
The output:
type = Lunch
time = 12:30
menu.entree = salad
menu.maincourse = steak
?>
