public class SpaceStrippedNode
extends AbstractVirtualNode
implements WrappingFunction
```
A StrippedNode is a view of a node, in a virtual tree that has whitespace text nodes stripped from it. All operations on the node produce the same result as operations on the real underlying node, except that iterations over the axes take care to skip whitespace-only text nodes that are supposed to be stripped. Note that this class is only used in cases where a pre-built tree is supplied as the input to a transformation, and where the stylesheet does whitespace stripping; if a SAXSource or StreamSource is supplied, whitespace is stripped as the tree is built.
