Oh! This brings up an important point! It’s possible to remove XML elements using the global delete keyword so “delete myXML.Harbs” or “delete myXML.Harbs[0]” would get rid of me.

You can add items to an XMLList using bracket notation as well. So there’s no way to know ahead of time how many indexes you’re going to need. I personally don’t see the problem with having Array functions on XMLList. It’s a very array-like object and I so no damage in having it behave completely like an array.

Yup. I’m just going to have to do all the heavy lifting myself without off-loading it to Document.
