All I need to do is add a new child node 'item' and if the number of childnodes of channel called item is greater than 50 remove them.

 

here is what I have tried so far with limited (no) success....

 

$file	=	$_SERVER['DOCUMENT_ROOT'] . '/xml/test.xml';
$dom	=	domxml_open_file($file);

$elements	=	$dom->get_elements_by_tagname ('item');

$nonodes	=	count($elements);

if	(
$nonodes	>	4
)
{
$remove	=	$elements[$nonodes - 1];
$child	=	$dom->dump_node($remove);
}

$element	=	$elements[0];

$newnode = $element->insert_before($element, $element);
$children = $newnode->children();
$attr = $children[1]->set_attribute("align", "left");



$xmlfile = $dom->dump_mem(true);
echo htmlentities($xmlfile);

 

now all that is doing is replacing the first item node with a line!!!!!

 

I need some kind fo loop to remove child nodes as there could be a situation where a few nodes get added manually so teh script needs to remove all nodes after the 50th one.

 

If anyone can help I woudl be very greatful.
