Update documentation on xmltree.items/mitems (#11930)

Browse source 
* Update documentation on `xmltree.items`/`mitems`

So far the documentation on `items` and `mitems` wasn't explicit about whether the iteration recurses down the node's children or not. I assumed recursion, which was wrong.

* Improve wording in comment

Use the more common and shorter word "direct".
