XML to array

[Brianfree]

Hi, i have the following working code to put xml values into an array.. however sometimes there can be multiple engine codes? how can i write to the array and read back from the array?

Please can anyone advise???

below is my code...

<?php
$REG = "";
if (isset($_POST["REG"])) {
	$VRM = $_POST["VRM"];
	$xml = file_get_contents("[URL unfurl="true"]http://www.xxx.com/gateway1_0?reg="[/URL] . $REG . ");
}


$p = xml_parser_create();
xml_parse_into_struct($p, $xml, $vals, $index);
xml_parser_free($p);
$output = array();
$desiredOutput = array(''VIN','VEHICLE_YEAR','MAKE','MODEL','ENGINE_NO'); //add the things you want to retrieve here
foreach ($desiredOutput as $o){
    if (isset($index[$o])){
        $key = $index[$o][0];
        $output[$o] = trim( $vals[$key]['value'] );
    }
}
session_register("$VIN");
session_register("$VEHICLE_YEAR");
session_register("$MAKE");
session_register("$MODEL");
session_register("$ENGINE_NO");

Many thanks,

Brian.

unless you know for sure whether there is more than one or exactly one each time you will need to use is_array() to determine whether to return a string or an array or whatever.

a well designed data structure from your source would mandate that any field that could have multiple entries was always delivered essentially as an array (or in xml as a sub node of a parent node engine numbers 1->many engine number)

Hi jpadie, 90% of the time a vehicle only has 1 engine code but occasionally there is more than one and will need to display it. The xml data i get back simply displays the following for 1 engine number…


<Engine_No>DT 4164 T</Engine_No>

If there is another engine code it is directly below in the xml…


<Engine_No>DT 4164 T</Engine_No>
<Engine_No>AT 3168 T</Engine_No>

If this helps?

Many thanks,

Brian

you'll have to manipulate the xml manually then.

assuming there is no parent element for those engine numbers, anyway.
