The remove_child() function seems to have a bug. if the parent node  of the node you are trying to delete is the same as the root node it will give you unexpected errors. I fixed this by checking if the parent node of the node i was deleting was the same as the document node. take a look at the function below if you are running into the same problem. $this->xmlData reffers to the domxml object inside the class i was using.

<?php

    function deleteNode($ref, $levels) {

        $parent = $ref->parent_node();

        $root = $this->xmlData->document_element();

        if($parent->node_name()==$root->node_name()) {

            $parent = $this->xmlData->document_element();

        }

        if($parent->remove_child($ref)) {

            return true;

        } else {

            exit("error removing node");

        }

    }

?>
