Convert XML to CSV with PHP

I’m using the following code to convert my XML file to a CSV format. Unfortunately, it seems to not be recognizing each entry in the XML and so the XML file ends up being blank.

<?php
$filexml='test.xml';
if (file_exists($filexml)) {
  echo 'File Exists';
$xml = simplexml_load_file($filexml);
  $f = fopen('test.csv', 'w');
  foreach ($xml->Item as $item) {
        fputcsv($f, get_object_vars($item),',','"');
  }
  fclose($f);
}
?>

An example of my XML file is below…

<Item MaintenanceType="C">
  <HazardousMaterialCode>N</HazardousMaterialCode>
  <ItemLevelGTIN GTINQualifier="UP">090127000380</ItemLevelGTIN>
  <PartNumber>0-1848-1</PartNumber>

Any ideas what I did wrong?

Answer

Try this

function createCsv($xml, $f)
{
    foreach ($xml->children() as $item) {
        $hasChild = (count($item->children()) > 0) ? true : false;
        if (!$hasChild) {
            $put_arr = array($item->getName(), $item);
            fputcsv($f, $put_arr, ',', '"');
        } else {
            createCsv($item, $f);
        }
    }
}

$filexml = 'test.xml';

if (file_exists($filexml)) {
    $xml = simplexml_load_file($filexml);
    $f = fopen('test.csv', 'w');
    createCsv($xml, $f);
    fclose($f);
}
