How do you rename a tag in SimpleXML through a DOM object?

Question

The problem seems straightforward, but I\'m having trouble getting access to the tag name of a SimpleXMLElement.

Let\'s say I have the follow XML structure:

Rather late but I came up with the fallowing solution by replacing the hell out of the xml. I thought this might help some people as I couldnt find any good solution on the web without copying all children.

function RenameNode(SimpleXMLElement $Entire_XML, SimpleXMLElement $Node, $New_Title) 
{    
    $Full_XML   = $Entire_XML->asXML();
    $Old_Title  = $Node->getName();
    $XML_String = $Node->asXML();
    $Replaced   = preg_replace("/$Old_Title/", $New_Title, $XML_String, 1);

    if (count($Node->children())>0) 
    {
        $Replaced = strrev(
            preg_replace(
                strrev("/$Old_Title/"), 
                strrev($New_Title), 
                strrev($Replaced), 
                1
            )
        );    
    }

    $Full_XML = str_replace($XML_String, $Replaced, $Full_XML);

    return simplexml_load_string($Full_XML);
}

Sidenote: This function can be simplified but I quickly rewrote this function in order to post this here. The original function I use looks a little bit different
