PHP traverses and parses XML into an array implementation code

/**
* Traverse and parse the xml file into an array
* edit bbs.it-home.org
*/
public function parseXML($menus){
 $result = array();
 foreach($menus as $menu){
 $tmparr = array ();

 //How to handle empty text nodes A
 if( $menu->nodeName !='#text'){

 // Skip over text nodes when retrieving child elements - Method B
 for handling empty text nodes for($i=1; $i<$menu->childNodes->length; $i+=2) {
 $aNode = $menu->childNodes->item($i);

 // Child element traversal
 $aNode->childNodes->length > 1 ? $tmparr[$aNode->nodeName] = $this->parseXML( $aNode->childNodes)
 : $tmparr[$aNode ->nodeName] = $aNode->nodeValue;
 }
 array_push($result,$tmparr);
 }
 }
 return $result;
}
$doc = new DOMDocument();
$doc-> ;load ( 'a.xml' );

//The first type, with empty text nodes
$menus = $doc->getElementsByTagName('siteMap')->item(0)->childNodes;

//The second type, clearly specify the label, and the sequence has no empty text nodes. But the child element still has empty nodes

$xpath = new DOMXPath($doc);
$query = "/siteMap/child::a";
$menus = $xpath->query($query);

In many PHP tutorials, there is content about PHP operating xml files. Today’s code is relatively simple and easy to understand, and is suitable for reference by beginners. Programmer's Home, I wish you all the best in your studies and progress.
