OpenCart - XML to MySQL

[at4re]

I have a XML document and a fresh OpenCart installation. The XML Document's content is:http://pastebin.com/59WeK4Qk I was able to get every tag and its value using \[code\]simplexml()\[/code\]:\[code\]$sxml = simplexml_load_file("products-sample.xml");foreach($sxml->products->children() as $products){ foreach($products->children() as $product) { echo 'Tag: '. $product->getName(). ' Value:' . $product.'<br />'; } echo '<hr />';}\[/code\]But I have no coding experience in opencart, so I was wondering is there any guide or tutorial on using opencart database.
