there is no lack of deleteChild function, you should use the php function unset()



<?php

unset($myxml->book[0]->page[22]);

unset($myxml->book[1]->page);

?>

Easy and fast deleting of a node:



<?php



$oNode = dom_import_simplexml($oSimpleXMLNodeToDelete);

$oNode->parentNode->removeChild($oNode);



?>



The node can have childs, attributes, and be anywhere in your document, it'll get deleted. The deletion will appear immediately in your SimpleXML object after calling removeChild, there's nothing else to do.

Here's a handy workaround to accommodate the lack of a $xml->deleteChild() function. It's not perfect, but it's a start (and it works for what I'm using it for):





<?php


// Workaround by Kobra.


function simplexml_deleteChild($parent, $childname, $parentname)


{


$temp = simplexml_load_string(str_replace("#","?","<#xml version=\"1.0\"#>\n<".$parentname.">\n</".$parentname.">"));


foreach($parent as $t)


{


  if($t->getName() != $childname)


  {


  $name = $t->getName();


  $value = eval("return \$parent->".$name.";");


  $temp->addChild($t->getName(), $value);


  }


}


return $temp;


}





?>





I have not tested this with multi-level XML files; but like I said, it's a start.

Object cloning ...



So using the 'clone' keyword here lets you work on $new separately, and attributes added to $new don't show up in $sxe



without the 'clone' all changes to $new will be reflected in the larger $sxe tree



                $new = clone $sxe->AddChild("comment",$comment);

                $new->AddAttribute("name",$name);

                $new->AddAttribute("url",$url);

                $new->AddAttribute("ip",$ip);

                $new->AddAttribute("time",$time);

Correct namespace usage:





<?php


$xml = new SimpleXMLElement('<root xmlns:itunes="http://example.com"/>');


$n = $xml->addChild("subtitle", "My Subtitle", " http://example.com");


?>





Incorrect namespace usage:





<?php


$xml = new SimpleXMLElement('<root xmlns:itunes="http://example.com"/>');


$n = $xml->addChild("subtitle", "My Subtitle", " itunes");


?>





The latter incorrect usage results in the following superfluous xmlns attribute:





<itunes:subtitle xmlns:itunes="itunes">My Subtitle</itunes:subtitle>





Whereas all you want is this:





<itunes:subtitle>My Subtitle</itunes:subtitle>

Replacing a node is an easy mod of the simplexml_append



function simplexml_replace(SimpleXMLElement $parent, SimpleXMLElement $new_child){

   $node1 = dom_import_simplexml($parent);

   $dom_sxe = dom_import_simplexml($new_child);

   $node2 = $node1->ownerDocument->importNode($dom_sxe, true);

   $node1->parentNode->replaceChild($node2,$node1);

}

<?php

// phpversion <= 5.1.2



function simplexml_addChild($parent, $name, $value=''){

    $new_child = new SimpleXMLElement("<$name>$value</$name>");

    $node1 = dom_import_simplexml($parent);

    $dom_sxe = dom_import_simplexml($new_child);

    $node2 = $node1->ownerDocument->importNode($dom_sxe, true);

    $node1->appendChild($node2);

    return simplexml_import_dom($node2);

}



function simplexml_addAttribute($parent, $name, $value=''){

    $node1 = dom_import_simplexml($parent);

    $node1->setAttribute($name,$value);

    return simplexml_import_dom($node1);

}



?>

Rob Richards and I have come up with a very easy way to append one SimpleXML tree to another:

<?php

function simplexml_append(SimpleXMLElement $parent, SimpleXMLElement $new_child){

   $node1 = dom_import_simplexml($parent);

   $dom_sxe = dom_import_simplexml($new_child);

   $node2 = $node1->ownerDocument->importNode($dom_sxe, true);

   $node1->appendChild($node2);

}

?>

And adding a textnode is also easy:

<?php

//$sxe1 (refers to SimpleXMLElement)

$node1 = dom_import_simplexml($sxe1);

$node1->appendChild(new DOMText("my text"));

?>



Ofcourse, you could use this to extend the SimpleXMLElement class and overwrite and improve the existing addChild function.



Have fun, Luuk Peters.
