Method Detail

getErrorElement

public Node getErrorElement()

Returns the element of the last error. Note: This method only returns non-null if the last erroneous node was of type Node.ATTRIBUTE_NODE.

validate

public 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.

If the node returned from this method is of type Node.ATTRIBUTE_NODE, the attribute's element can be queried by calling the getErrorElement() method.

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.
