public interface VirtualNode
extends NodeInfo
```
This interface is implemented by NodeInfo implementations that act as wrappers on some underlying tree. It provides a method to access the real node underlying the virtual node, for use by applications that need to drill down to the underlying data.

- Method Detail
  - getUnderlyingNode
```
java.lang.Object getUnderlyingNode()
```
    Get the node underlying this virtual node. Note that this may itself be a VirtualNode; you may have to drill down through several layers of wrapping.
    In some cases a single VirtualNode may represent an XPath text node that maps to a sequence of adjacent nodes (for example text nodes and CDATA nodes) in the underlying tree. In this case the first node in this sequence is returned.
    
    Returns:
    
    The underlying node.
  - getRealNode
```
java.lang.Object getRealNode()
```
    Get the node underlying this virtual node. If this is a VirtualNode the method will automatically drill down through several layers of wrapping.
    In some cases a single VirtualNode may represent an XPath text node that maps to a sequence of adjacent nodes (for example text nodes and CDATA nodes) in the underlying tree. In this case the first node in this sequence is returned.
    
    Returns:
    
    The underlying node.
