DomDocument: setting attributes to a new node

[Sebastian Araya]

Hello,
I'm trying to create a single function to append new nodes to a
DOMDocument object:

public function addElement( $element, $name, $value = '', $attrs = Null
)
{
if( !( $created = $this->createElemen t( $name, $value ) ) )
throw new Exception( 'Could not create a new node ' );

if( !( $child = $element->appendChild( $child ) ) )
throw new Exception( 'Could not append a new node ' );

// Process and attachs the new attributes from array $attrs if
any...
// if( $attrs )
// foreach( $attrs as $attribute => $value )
// ...
}

So far, so good. Now I want to set attributes and its values of the
recent created node (playing with createAttribute () and setAttribute(),
but I can't get the DOMElement from the new child DOMNode. Is it
possible without issuing getElementsByTa gName() or getElementById( ) ??

Is another easy way -using DomDocument object- to create a new
element (such <table width="50%" border="0">...</table>) which has its
attributes and its values ??

Thanks in advance,
Sebastián Araya

<?php

class Dom {
private $dom;

function __construct() {
$this->dom = new DomDocument;
}

function addElement($nam e, $value = '', $attrs = array()) {
$element = $this->dom->createElement( $name, $value);
foreach ($attrs as $a => $v) {
$element->setAttribute($ a, $v);
}
$this->dom->appendChild($e lement);
}

function saveXML() {
return $this->dom->saveXML();
}
}

$dom = new Dom;
$dom->addElement('ro ot', 'test', array('foo' => 'bar'));
print htmlentities($d om->saveXML());

?>

You could use the following (although not very pretty):

<?php

class Dom {
private $dom;

function __construct() {
$this->dom = new DomDocument;
}

function addElement($ele ment) {
$dom = DomDocument::lo adXML($element) ;
$node = $this->dom->importNode(
$dom->documentElemen t,
true
);
$this->dom->appendChild($n ode);
}

function saveXML() {
return $this->dom->saveXML();
}
}

$dom = new Dom;
$dom->addElement('<r oot foo="bar">test</root>');
print htmlentities($d om->saveXML());

?>
