PHP: How do I loop through every XML file in a directory? (2 answers)

Closed 8 years ago.

Should I read many xml file in a folder and extract from these data. I have no problem to read the folder with this code

<?php
$dir = "Dati/xml/nonletti/";
  if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
    while (($file = readdir($dh)) !== false) {
      if (($file !== '.') && ($file !== '..') ) {
  echo "$file \n";
  }
}
  closedir($dh);
}
}
?>

but if I try to use simplexml to read all the files do not I see anything

<?php
$dir = "Dati/xml/nonletti/";
if (is_dir($dir)) {
  if ($dh = opendir($dir)) {
    while (($file = readdir($dh)) !== false) {
      if (($file !== '.') && ($file !== '..') ) {
    $xml = simplexml_load_file($file);  
        $RGSostituzione = $xml->attributes()->Sostituzione;
    echo "<li>File $file - <b>Sostituzione:</b> $RGSostituzione</li>";
    }
  }
  closedir($dh);
  }
}
?>

Can you help me and tell me how to do? thank's- Filippo

Answer 1

When you read the files in the directory, you only get the base filename, not the full path. So you need to prepend the path when you do the SimpleXML call.

Change to:

$xml = simplexml_load_file($dir . $file);  

Answer 2

$xml = simplexml_load_file($dir . $file);

https://php.net/readdir (returns filename, not entire file path)

https://php.net/simplexml_load_file (takes full file path)
