```
public class Node
extends Object
```
Represents an XML node with name, value, attributes, and child nodes.
This class provides a tree-like structure for representing XML documents. Each node can have a name, value, attributes, and child nodes. Nodes can be created independently or as part of an XML document tree.
Key features:
- Node name and value management
- Attribute storage and retrieval
- Parent-child node relationships
- XML string output with proper escaping
- User data attachment for application-specific information
