PHP SimpleXML how do i get this value?

Question

How would i go around retrieving the value of <TotalNew> in the example file below? I am unfamiliar with simplexml. I tried to access it as following: ItemLookupResponse->Items->Item->TotalNew but it did not produce a result.

Anyone who can point me out how to achieve this ? Thanks in advance

Your XML has an error. Add the following to the end of your XML..

    </Items>
</ItemLookupResponse>

Then you can use the following.. ..bearing in mind that there may be multiple <item> elements inside <items> , so you will have to loop through them.

$xml = simplexml_load_string($string);

foreach ($xml->Items as $item){

    echo $item->Item->OfferSummary->TotalNew->__toString();

}

If you can guarantee that there will only ever be one <Item> inside <Items> , or you just want to target the first <Item> , you could achieve this without a loop, by targeting the first value of the <Items> array using Item[0] .

echo $xml->Items->Item[0]->OfferSummary->TotalNew->__toString();
