class DOMElement {

__construct ( string name [, string value [, string namespaceURI]] )

}

Creates a new DOMElement object. This object is read only. It may be appended to a document, but additional nodes may not be appended to this node until the node is associated with a document. To create a writeable node, use DOMDocument->createElement() or DOMDocument->createElementNS().

Список параметров

name: The tag name of the element. When also passing in namespaceURI, the element name may take a prefix to be associated with the URI.
value: The value of the element.
namespaceURI: A namespace URI to create the element within a specific namespace.

Пример 1. Creating a new DOMElement

<?php $dom = new DOMDocument('1.0', 'iso-8859-1'); $element = $dom->appendChild(new DOMElement('root')); $element_ns = new DOMElement('pr:node1', 'thisvalue', 'http://xyz'); $element->appendChild($element_ns); echo $dom->saveXML(); /* <?xml version="1.0" encoding="iso-8859-1"?> <root><pr:node1 xmlns:pr="http://xyz">thisvalue</pr:node1></root> */ ?>

Dennis:



DOMDocument::saveXML can take in a node as a parameter and output the XML as a string. Perhaps this is what you were looking for?

I'm just starting to get into the DOM methods and finding it pretty challenging. 



One of the obstacles is that once you've got a node, there doesn't seem to be any way to see what's inside it (at least I haven't been able to find it). You'd expect (I did) print_r to show you the properties (attributes) of the node, but all it tells you is the object type. 



So I wrote this little function to mimic the way I think print_r should work: 



<?php

function nodeDump($node)

{

    $output = print_r($node, TRUE);

    $output = str_replace(")\n", '', $output);         

    $output .= '    ' . '[tagName] => ' . $node->tagName . " \n";

    

    $numOfAttribs = $node->attributes->length;        

    for ($i = 0; $i < $numOfAttribs; $i++)

    {

        $output .= '    [' . $node->attributes->item($i)->nodeName . '] => ' . $node->attributes->item($i)->nodeValue . " \n"; 

    }

    

    $output .= '    [nodeValue] => ' .  $node->nodeValue;    

    $output .= ')';

    return $output;

}

?>



OK - to really work like print_r it would also go through all the childNodes recursively, but it's a start.

If you like to view an element simply do:



<?php

echo htmlentities($element->C14N());

?>



Undocumented but found ;)
