As IXMLDOMNode is a COM interface, it includes reference-counting semantics.
When a node is removed from the tree and it's reference count drops to zero,
the memory is reclaimed. Parent nodes addref their children. Keeping a
node alive has the side effect of keeping it's owner document alive. In the
case that there are no outstanding nodes, still addref'd, when a
IXMLDOMDocument's refcount goes to zero, the entire document is reclaimed.

Subject: MSXML Memory Management
Something more mundane regarding MS. When using MSXML and IE, is there a
way to permanently remove an XMLDOMNode object
or can one only remove it from the tree. Over a long set
of operations, without a means to get rid of it out
of memory, obvious bad things happen. IOW, what is
the garbage collection policy for MSXML?
