php - using simplexml_load_file() to get attributes from xml file for Amazon Affiliate API -


i using amazon affiliate api here. new of actually.

i have php code generate working url products, having issues extracting data url's generated xml. looking return formattedprice xml.

here example of xml file: https://pastebin.com/hnttevfv

here code trying pull "formattedprice". neither of examples below working , returning empty values.

sidenote: $request_url full http:// valid url of xml file.

$getxml = simplexml_load_file($request_url);  $price = $getxml->itemlookupresponse->items->item->itemattributes->listprice['formattedprice'];

nor does

$price = $getxml->itemlookupresponse->items->item->itemattributes->listprice->formatedprice;

every xml document has single "root element". in example, top-level element <itemlookupresponse>.

when load document in simplexml, first object gives root element. access chlidren of element ->elementname notation.

so instead of $getxml->itemlookupresponse->items should write $getxml->items.
