DOM Model- The W3C has broken down the DOM 5 into a tree structure of nodes of varying 4 types. The Node interface is the base interface 3 for all elements. All objects implementing 2 this interface expose methods for dealing 1 with children.
$dom=new DomDocument;
$dom->Load("file.xml");
$root=$dom->documentElement; // Root node
According to the PHP docs DOMElement is a subclass of DOMNode, so it should 1 inherit the hasChildNodes()-method.
Prior to php 5.1.3 this guy has it licked
https://macfoo.wordpress.com/2009/06/03/getting-the-root-node-from-an-xml-string
/**
* function getXMLRootNode
* @param string An xml string
* @return string Return XML root node name
*/
function getXMLRootNode($xmlstr)
{
// Create DOM model
$doc = new DOMDocument();
// Load the XML string
if(!$doc->loadXML($xmlstr))
{
throw new Exception('Unable to parse XML string');
}
// Find the root tag name
$root = $doc->documentElement;
if(!isset($root))
{
throw new Exception('Unable to find XML root node');
}
if(!isset($root->nodeName))
{
throw new Exception('Unable to find XML root node name');
}
return $root->nodeName;
}
