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");
        }
    }
?>
