Help with simplexml

Courtney · 03-02-2010, 02:00 AM

I am totally stumped. I have managed to use simpleXML and XPATH to get this far.. now I am trying to neatly extract the keys and values from the following XML string. Trouble is I cannot figure out how to do it so that the number of [reagents] does NOT matter. Some strings will have 1 [reagent] some 15.

XML as I can access it:

Code:

<product id="12049" name="Corn Bread" icon="INV_Corn_09" minCount="1" maxCount="1">
  <reagent id="4339" name="Corn Meal" quality="1" icon="INV_Baking_03" count="2" /> 
  <reagent id="4291" name="Flour" quality="1" icon="INV_Baking_02" count="3" /> 
</product>

Code:

SimpleXMLElement Object
(
    [@attributes] => Array
        (
            [id] => 12049
            [name] => Corn Bread
            [icon] => INV_Corn_09
            [minCount] => 1
            [maxCount] => 1
        )

    [reagent] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [@attributes] => Array
                        (
                            [id] => 4339
                            [name] => Corn Meal
                            [quality] => 1
                            [icon] => INV_Baking_03
                            [count] => 2
                        )

                )

            [1] => SimpleXMLElement Object
                (
                    [@attributes] => Array
                        (
                            [id] => 4291
                            [name] => Flour
                            [quality] => 1
                            [icon] => INV_Baking_02
                            [count] => 3
                        )

                )

        )

)

Can someone point me in the right directon? This is mainly for learning and I am a novice.

what is the key and what is the value?

Looking for a foreach loop I suppose to grab all of the keys and values. I cannot figure out how to get the item listed under:

Code:

[reagent] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [@attributes] => Array

a look in the manual will give the solution

PHP Code:


			
foreach ($reagent->attributes() as $key => $value)
