      ro.sync.ecss.extensions.commons.XPointerElementLocator

public class XPointerElementLocator
extends ElementLocator

Element locator for links that have the one of the following patterns:

• element(elementID) - locate the element with the same id
• element(/1/2/5) - A child sequence appearing alone identifies an element by means of stepwise navigation, which is directed by a sequence of integers separated by slashes (/); each integer n locates the nth child element of the previously located element.
• element(elementID/3/4) - A child sequence appearing after an NCName identifies an element by means of stepwise navigation, starting from the element located by the given name.
