Here we use the XMLReader extension to parse and process the file. Another advantage of XMLReader is that it reads data in the form of Stream, that is, even if it is faced with an extremely large xml file, it can still be processed calmly. Here’s what we do with the above files:




Copy code

$nodeName = $reader->name;
                                                                                 If($reader->nodeType == XMLReader::TEXT && !empty($nodeName)){
switch($nodeName){
case 'name':
$name = $reader->value;
break;
case 'channel':
$channel = $reader->value;
break;
case 'start':
$start = $reader->value;
break;
case 'duration':
$duration = $reader->value;
break;
                                                                                                                                                                             } 
$reader->close();
