• Diubah menjadi MySQL ke MySQLi ! Sangat penting untuk mulai berubah sekarang selagi bisa! =)
• Gunakan Fungsi! Anda menulis $xml->startElement &$xml->endElement berulang kali, letakkan di addNode() metode.
• Menambahkan 'Root ' node untuk menambahkan setiap baris database juga.
• Gunakan CData (<![CDATA[text for inclusion within CData tags]]> ), ini akan membantu untuk melarikan diri dengan aman dari kemungkinan karakter yang sulit
