Class XML

java.lang.Object
javaforce.XML
public class XML extends Object
XML encapsules a complete XML file.
Each XML tag (element) is treated as a node in the tree. The read() functions include a callback interface so you can further tweak the layout of the XML tree.
Then you can write() it back to a file. Typical XML Tag:
<name [attributes...]> content | children </name>
Singleton XML Tag: (no children)
<name [attributes...] />
Caveats:
Only leaf nodes can contain actual data (content) (in other words @XmlMixed is not supported).
Mixed tags are read, but when written the content is lost.
There must be only one root tag.
Support for the standard XML header is provided (see header).
readClass() and writeClass() support : int, short, byte, float, double, boolean, String, and Custom Classes.
Arrays of any of these.
All classes and fields MUST be public. static and transient members are skipped. No special annotations are required.

    • getTag

      public XML.XMLTag getTag(Object[] objs)
      Returns a node based on the objs[] path.

    • setTag

      public void setTag(XML.XMLTag tag, String name, String attrs, String content)
      Sets the name, attrs and content for an existing node.

    • writeClass

      public void writeClass(XML.XMLTag tag, Object obj)
      Writes all children of tag to object.

    • writeClass

      public void writeClass(Object obj)
      Writes entire XML tree to object.

    • readClass

      public void readClass(XML.XMLTag tag, Object obj)
      Reads all fields from an object and places into tag.

    • readClass

      public void readClass(String rootName, Object obj)
      Reads entire XML tree from object (deletes entire tree first).
      Parameters:
      rootName - = name to assign to root tag.
