CSV to XML add more header - php

Question

I've got the following problem:
I have a csv file, that I can convert to XML via a php script.
This way, every field goes under the same row in the xml, and I want the product_sku field go under a different row, for example call it SKU_row.
The CSV looks like this:
my CSV file
The XML looks like this:
my XML file
PHP file code that I run to convert the CSV to XML:
error_reporting(E_ALL | E_STRICT);
ini_set('display_errors', true);
ini_set('auto_detect_line_endings', true);
function PrepareXMLName($PrepareString)
{
$PrepareString = str_replace(" ","",$PrepareString);
$PrepareString = preg_replace('#\W#', '', $PrepareString);
$PrepareString = str_replace("ZSPAZESZ","",$PrepareString);
$PrepareString = strtolower($PrepareString);
return $PrepareString;
}
$inputFilename = 'faszom.csv';
$outputFilename = 'faszom.xml';
// Open csv to read
$inputFile = fopen($inputFilename, 'rt');
// Get the headers of the file
$headers = fgetcsv($inputFile);
// Create a new dom document with pretty formatting
$doc = new DomDocument();
$doc->formatOutput = true;
// Add a root node to the document
$root = $doc->createElement('rows');
$root = $doc->appendChild($root);
// Loop through each row creating a <row> node with the correct data
while (($row = fgetcsv($inputFile)) !== FALSE)
{
$container = $doc->createElement('row');
foreach ($headers as $i => $header)
{
$header = str_replace(chr(32),"_",trim($header));
$header = strtolower($header);
if($header==''){ $header = 'empty';}
$header = PrepareXMLName($header);
if(is_numeric($header)) { $header = "number-". $header; }
//echo "HERE: " . $header . "<br />";
$child = $doc->createElement($header);
$child = $container->appendChild($child);
$value = $doc->createTextNode($row[$i]);
$value = $child->appendChild($value);
}
$root->appendChild($container);
}
header("Content-type: text/xml");
$strxml = $doc->saveXML();
$handle = fopen($outputFilename, "w");
fwrite($handle, $strxml);
fclose($handle);
echo $doc->saveXML();
How can I do in this PHP file, to let it put the product_sku fields under a different row, to be it separated from the row in which customer data's are?

Answer 1

XML allows you to group on a further level. So instead of your flat row model:
<rows>
<row>
<product_sku>L162L</product_sku>
<order_entity_id>31</order_entity_id>
<order_customer_firstname>Teszt</order_customer_firstname>
<product_qty_ordered>1.0000</product_qty_ordered>
</row>
You can group further on depending on the context of the data, for example by order, product and customer:
<rows>
<row>
<product>
<sku>L162L</sku>
<qty_ordered>1.0000</qty_ordered>
<product>
<order>
<entity_id>31</entity_id>
<customer>
<firstname>Teszt</firstname>
</customer>
</order>
</row>
But this depends entirely of what you want and from your question I don't see any reason on why to do it this, that or any other way nor what stands in your way to do whatever you want.
