Cannot get XML structure right - php

Question

I am working with XML and php. I am trying to get an array of PHP result to this XML format with two <customer> customers, I can get 1 but dont know how to do it for 2 customers in an array.
<?xml version="1.0"?>
<NewSLSCase>
<Identification CientNo="4xxx" CLientBatchNo="1" IJBatchNo="1" HubNo="201048" ClientEmailAddress1="etunimi.sukunimi#yritys.fi" ClientEmailAddress2="etunimi.sukunimi#yritys.fi"/>
<LedgerSet>
<Ledger ProductionUnit="04" LedgerNo="4xxxxx">
<CustomerSet>
<Customer No="123456" Name="Farhana" Address1="Myhouse" ZipCode="40100" City="Vantaa" LanguageCode="FIN" CountryCode="FI" VatNo="01011-111A" TypeCode="C"/>
<Customer No="123457" Name="Asiakas Anna" Address1="Asiakastie 2" ZipCode="00100" City=" Helsinki" LanguageCode="FIN" CountryCode="FI" VATNo="010111-111A" TypeCode="C"/>
</CustomerSet>
<InvoiceSet>
<Invoice InvoiceNo="123456"/>
<InvoiceHeader InvoiceHeaderType="L" InvoiceCustomerNo="123456" InvoiceCurrency="EUR" InvoiceDate="2011-04-08" InvoiceDueDate="2011-05-15" InvoiceAmount="57.00" ClientOCRReference="908000101800031186" InvoiceReferenceText3="150,00" InvoiceReferenceText4="Laskuille tulostuva" InvoiceReferenceText5="IBAN" InvoiceReferenceText6="BIC"/>
</InvoiceSet>
</Ledger>
</LedgerSet>
</NewSLSCase>
I wrote the codes for just getting one ` but adding another one is something I am truly not sure off.
Here is the array, did not copy the whole thing since its big, but I am using a small part of it for testing.
array(2) (
[0] => stdClass object {
ID => (string) 177835
currency => (string) Asiakas Anna
type => (string) Asiakastie 2
}
[1] => stdClass object {
ID => (string) 177840
Name=> (string) Farhana
Address=> (string) Myhouse
.....
Here is the whole XML format
$result = $this->invoice_page->getInvoiceByID('20241'); //this is the array
$xml = new DomDocument('1.0');
$xml->formatOutput = true;
$NewSLSCase = $xml->createElement("NewSLSCase");
$xml->appendChild($NewSLSCase);
$Identification = $xml->createElement("Identification");
$Identification->setAttribute("CientNo","4xxx");
$Identification->setAttribute("CLientBatchNo", "1");
$Identification->setAttribute("CLientBatchNo", "1");
$Identification->setAttribute("IJBatchNo", "1");
$Identification->setAttribute("HubNo", "201048");
$Identification->setAttribute("ClientEmailAddress1", "etunimi.sukunimi#yritys.fi");
$Identification->setAttribute("ClientEmailAddress2", "etunimi.sukunimi#yritys.fi");
$NewSLSCase->appendChild($Identification);
$LedgerSet = $xml->createElement("LedgerSet");
$NewSLSCase->appendChild($LedgerSet);
$Ledger = $xml->createElement("Ledger");
$Ledger->setAttribute("ProductionUnit","04");
$Ledger->setAttribute("LedgerNo", "4xxxxx");
$LedgerSet->appendChild($Ledger);
$CustomerSet = $xml->createElement("CustomerSet");
$Ledger->appendChild($CustomerSet);
$Customer = $xml->createElement("Customer");
$Customer->setAttribute("No","123456");
$Customer->setAttribute("Name", $result['Fullname']);
$Customer->setAttribute("Address1", $result['Address_street']);
$Customer->setAttribute("ZipCode", $result['Address_zip']);
$Customer->setAttribute("City",$result['Address_city']);
$Customer->setAttribute("LanguageCode", "FIN");
$Customer->setAttribute("CountryCode","FI");
$Customer->setAttribute("VatNo", "01011-111A");
$Customer->setAttribute("TypeCode","C");
$CustomerSet->appendChild($Customer);
$InvoiceSet = $xml->createElement("InvoiceSet");
$Ledger->appendChild($InvoiceSet);
$Invoice = $xml->createElement("Invoice");
$Invoice->setAttribute("InvoiceNo","123456");
$InvoiceSet->appendChild($Invoice);
$InvoiceHeader = $xml->createElement("InvoiceHeader");
$InvoiceHeader->setAttribute("InvoiceHeaderType", "L");
$InvoiceHeader->setAttribute("InvoiceCustomerNo","123456");
$InvoiceHeader->setAttribute("InvoiceCurrency", "EUR");
$InvoiceHeader->setAttribute("InvoiceDate","2011-04-08");
$InvoiceHeader->setAttribute("InvoiceDueDate", "2011-05-15");
$InvoiceHeader->setAttribute("InvoiceAmount","57.00");
$InvoiceHeader->setAttribute("ClientOCRReference", "908000101800031186");
$InvoiceHeader->setAttribute("InvoiceReferenceText3","150,00");
$InvoiceHeader->setAttribute("InvoiceReferenceText4","Laskuille tulostuva");
$InvoiceHeader->setAttribute("InvoiceReferenceText5",$result['IBAN']);
$InvoiceHeader->setAttribute("InvoiceReferenceText6",$result['BIC']);
$InvoiceSet->appendChild($InvoiceHeader);
echo "<xmp>".$xml->saveXML()."</xmp>";
What the above code, gives me is this
<?xml version="1.0"?>
<NewSLSCase>
<Identification CientNo="4xxx" CLientBatchNo="1" IJBatchNo="1" HubNo="201048" ClientEmailAddress1="etunimi.sukunimi#yritys.fi" ClientEmailAddress2="etunimi.sukunimi#yritys.fi"/>
<LedgerSet>
<Ledger ProductionUnit="04" LedgerNo="4xxxxx">
<CustomerSet>
<Customer No="123456" Name="Farhana" Address1="Myhouse" ZipCode="40100" City="Vantaa" LanguageCode="FIN" CountryCode="FI" VatNo="01011-111A" TypeCode="C"/>
</CustomerSet>
<InvoiceSet>
<Invoice InvoiceNo="123456"/>
<InvoiceHeader InvoiceHeaderType="L" InvoiceCustomerNo="123456" InvoiceCurrency="EUR" InvoiceDate="2011-04-08" InvoiceDueDate="2011-05-15" InvoiceAmount="57.00" ClientOCRReference="908000101800031186" InvoiceReferenceText3="150,00" InvoiceReferenceText4="Laskuille tulostuva" InvoiceReferenceText5="IBAN" InvoiceReferenceText6="BIC"/>
</InvoiceSet>
</Ledger>
</LedgerSet>
</NewSLSCase>
I have no clue how to add a foreach to get two customers information.

Answer 1

Use foreach loop through customers:
foreach ($customersArray as $customerData) {
$Customer = $xml->createElement("Customer");
$Customer->setAttribute("No",$customerData->ID);
//set all attributes like that
$CustomerSet->appendChild($Customer);
}
