i have a xml file and I am trying to access the data in a xml file but it return an empty array.

Could the problem be in the file itself?

I have tried to use Basic SimpleXML usage this is my php code i used:

<?php
libxml_use_internal_errors(TRUE);

$xml = file_get_contents("https://egytech4uu.herokuapp.com/data.xml");

$XML = simplexml_load_string($xml, "SimpleXMLElement", LIBXML_NOCDATA);
$json = json_encode($XML);
$arr = json_decode($json,TRUE);
print_r($arr);

?>

Answer 1

Here's one for you:

<?php
$xmldata = file_get_contents("https://egytech4uu.herokuapp.com/data.xml");
$xmlparser = xml_parser_create();
$arr = [];
xml_parse_into_struct($xmlparser, $xmldata, $arr);
xml_parser_free($xmlparser);
print_r($arr);

So what's going there? It returns a flat array, but for each node at least we can see its level. As mentioned in the comments, this is not the best way to parse XML, only a last resort kind of thing.
