  +--jv.loader.PsXmlNode

public class PsXmlNode

extends java.lang.Object

implements java.io.Serializable

Node of an XML resource tree. Each node corresponds to an XML element which consists of

1. a unique string type which is the name of the XML element
2. a set of unordered attribute pairs (key, value) of strings
3. a link to its father node
4. an ordered set of links to all its child nodes
5. a link to the next sibling node (i.e. brother resp. sister)
6. a content string
   

In mixed mode, the node can have children mixed with sequences of text. In mixed mode, the content is not a single string.

Version:

07.01.01, 1.50 revised (kp) Mixed mode added.
04.02.00, 1.00 created (kp)
