Kara, thank you for your comment. You’re right. I implemented the changes in the article.

Thanks for posting this. I just found one error when trying to use it… You need to access the nodes in xml, not xml.children initially. You will check the child nodes during recursion (the way it was before, every other level of the tree was being skipped completely). I have posted the corrected version below.

public function goThrough(xml:XMLList, removeData:Array):void
{
    if (xml.length() > 0)
    {
        for (var i:int = xml.length() - 1; i >= 0 ; i--)
        {
            if (removeData.indexOf(xml[i].@id_data.toString()) != -1)
            {
                debugText.text += xml[i].@id_data + "\n";
                delete xml[i];
            } else {
                if (xml[i].children())
                {
                    goThrough(xml[i].children(),removeData);
                }
            }
        }
    }
}

Cengiz, thanks for the comment. You’re right if you tried to delete to consecutive nodes in the same parent it won’t work.

Instead of decreasing the “i” variable, as you proposed, I’m looping from the last node to the first.

Now it should work.

Good work, thanks! But fails while deleting following nodes. Needs to decrement index (i--) after deleting the node.

AS3 does have a very poorly documented “delete” function that you can use to delete a node and all its children. You can see an example I posted on Kirupa.

He great stuff, here something simular but with an arraycollection.
