Method Detail

getNodeValue

public static String getNodeValue(Element base,
                                  Path path)

Gets the value of the node at the given path relative to the given base element.

For element nodes the value is the text content and for the attributes node the attribute value.

Returns:

the node value or null if no such node was found

visitNodes

                              DOMHelper.NodeVisitor visitor,
                              Collection<Object> result)

Visits the nodes selected by the given path using the given visitor.
