Method – 4

A common pitfall is to forget that json_encode() doesn’t respect elements/data with a textvalue and attribute(s). it’ll select one in all those, that means dataloss. The operate below solves that downside. If one decides to travel for the json_encode/decode method, the subsequent operate is suggested.

function json_prepare_xml($xml_object)
{
 
foreach($xml_object->childNodes as $xml_val)
{
if($xml_val->hasChildNodes())
{
json_prepare_xml($xml_val);
} else
{
if($xml_object->hasAttributes() && strlen($xml_object->nodeValue)){
$xml_object->setAttribute("nodeValue", $xml_val->textContent);
$xml_val->nodeValue = "";
}
}
}
}
 
$xml_url = "books-xml.xml";
 
$xml_object = new DOMDocument();
$xml_object->loadXML( file_get_contents($xml_url) );
json_prepare_xml($xml_object);
$string_xml = simplexml_load_string( $xml_object->saveXML() );
$json_data = json_decode( json_encode( $string_xml ) ) );
