## Class PsXmlNode

- java.lang.Object
- - jv.rsrc.PsXmlNode

- All Implemented Interfaces:
    java.io.Serializable

      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.

      Parameters:
        `writer` - Write all data to this stream
        `node` - node to save.
        `tab` - indentation tab which is increased on children, maybe null string.
