Method Detail

validate

public final Node validate(Node node)

Given a node which is a DOM tree (or subtree), validate the tree against the current DTD. If the tree is valid, return null. If the subtree is invalid return the highest (closest to the root) and left most node which causes the tree to be invalid.

Parameters:

node - The node representing the root of the DOM subtree to be revalidated.

Returns:

null if the subtree is valid or the first (highest and leftmost) node where the tree is invalid.
