能否新增一个获取某个元素在其兄弟节点中的索引值，或者可以直接获取该元素的上一个节点和下一个节点

现在我们有一个场景是 1234567 | connect 1234568 | connect 1234569 | connect 1234566 | connect

而元素列表如下： "12345.." 和 “connect” 全都在同一级，没有对应的关系

左侧的数字是随时变动的，我无法直接通过左侧数字定位到右侧的connect 的按钮

我自己写了一个解决的方案，但是速度不尽如人意，想来应该还是得从更底层去解决这个 def index(self): """ Returns the index of the element in the subset of the parent element

    """
    start = time.time()
    sub_query = build_query(None)  # as placeholder
    query = ('-', (self.query, sub_query))
    obj = UIObjectProxy(self.poco)
    obj.query = query
    position = [x.get_position()  for x in obj]
    return position.index(self.get_position())

def last_sibling(self):
    """
    Returns the sibling to the left of an element

    """
    sub_query = build_query(None)
    query = ('-', (self.query, sub_query))
    obj = UIObjectProxy(self.poco)
    obj.query = query
    return obj[self.index() - 1]

def next_sibling(self):
    """
    Returns the sibling to the right of an element

    """
    sub_query = build_query(None)
    query = ('-', (self.query, sub_query))
    obj = UIObjectProxy(self.poco)
    obj.query = query
    return obj[self.index()+1]
