Table 1 Code Against the XML Object Model. The XML object model exposes several useful interfaces. The object model itself is simple, composed of three objects: the XML Document, the XML Element, and the Element Collection. The XML document model sports a tree-like structure. For example, it begins with a top-level element and branches out to descendants. Navigating this tree enables you to retrieve important information about the source document.
