/**
* Parses an XML string into a structured JavaScript object.
* Parses an XML string into a plain JavaScript object.
* Each tag becomes a key. Attributes and child tags are merged as
* sibling properties on that tag's object. Duplicate tag/attribute
* names are collapsed into arrays. Text-only tags resolve to their
* (optionally numeric) value; if a tag has both text and attributes/
* children, the text is kept under a `_text` key.

* @returns {Object} An object with `tag`, `attributes`, and `children` properties
