next_node(#)

I want the 12th next node. @basic.search("b[@class='blackcatheader']")[0].next_node.next_node.next_node.next_node.next_node.next_node.next_node.next_node.next_node.next_node.next_node.next_node or @basic.search("b[@class='blackcatheader']")[0].next_node(12)

What about something like (1..12).inject(header) { |node,_| node.next_node } ?

Replying to tec:

What about something like (1..12).inject(header) { |node,_| node.next_node } ?

Is this a suggestion for writing .next_node 12 times or the test code I posted?

Using inject would prevent 0 and negative indexes.

[why]

Ohh, I like the range idea, too, though. Maybe it could accept an int or a range. Hmm. Negative values would turn next_node into previous_node, though. Confusing.

Probably better to add a nodes_at method which can take any number of int and range combinations.

 #!ruby
 ele.nodes_at(-3..-1, 1..3) # gets three nodes before and three after
 ele.nodes_at(1, 5, 7) # gets three nodes at offsets below the current node
 ele.nodes_at(0, 5..6) # the current node and two others

[why]

Okay, [90] includes both siblings_at and nodes_at.
