DOM Xpath get desired result only - php

Question

$some_link = 'http://www.example.com';
$abc = 'killer';
$bcd = 'awsome';
$cde = 'qwerty';
$dom = new DOMDocument;
$dom->preserveWhiteSpace = false;
#$dom->loadHTMLFile($some_link);
$html = getTags( $dom, $abc, $bcd, $cde );
echo $html;
function getTags( $dom, $abc, $bcd, $cde ){
$html = '';
$domxpath = new DOMXPath($dom);
$newDom = new DOMDocument;
$newDom->formatOutput = true;
$defffff = $domxpath->query("//$abc" . '[#' . $bcd . "='$cde']");
// since above returns DomNodeList Object
// converting to string(html)
$i = 0;
while( $myItem = $defffff->item($i++) ){
$node = $newDom->importNode( $myItem, true ); // import node
$newDom->appendChild($node); // append node
}
$html = $newDom->saveHTML();
return $html;
}
?>
this is the whole code. it is returning multiple results in a row, now what I want is to have ONLY the result no.1 and no.5. How can I do it?
I am new to DOM, tried several things but no success. Thanks in Advance

Change this
$i = 0;
while( $myItem = $defffff->item($i++) ){
$node = $newDom->importNode( $myItem, true ); // import node
$newDom->appendChild($node); // append node
}
into this, in order to append only selected nodes
$i = 0;
while( $myItem = $defffff->item($i++) ){
if ($i==0 or $i==4){
$node = $newDom->importNode( $myItem, true ); // import node
$newDom->appendChild($node); // append node
}
}
or you if you know the indexes you want already, you can do this
$myIndexes = array (0,4);
foreach ($myIndexes as $i){
$myItem = $defffff->item($i++);
$node = $newDom->importNode( $myItem, true ); // import node
$newDom->appendChild($node); // append node
}
