Class DOMHandler

  cz.cuni.mff.ksi.jinfer.xsdimportdom.DOMHandler

public class DOMHandler
extends Object

Class responsible for building rule-trees from DOM tree.

Extracts information from existing DOM tree to create rule-trees. Rule-trees are tree data structures, where vertices are instances of Element and edges are the relations between them stored in Regexp instances within vertices. Every vertex is a rule by itself, so in order to obtain IG rules, one must extract all Elements from a rule-tree.

Please read package info.

Create rule-trees from direct children of the root node of DOM tree.

Returns list of Elements containing complete rule-trees of the top level tags. This method recursively builds rule-trees for all its sub-nodes, thus should be invoked only once, on the schema tag node itself.

Parameters:

root - Root of the DOM tree, (schema tag) node.

Returns:

Rule-trees of all top level element tags, or empty list if schema was empty.

Throws:

XSDException

InterruptedException
