Re: removing nodes from Nokogiri::XML::NodeSet

Show all headers | View raw

It doesn't remove it though. I also don't want specifically to remove 
the first or last node, often I want to remove one somewhere in the 
middle of the array.

puts nodes.length
nodes[0].remove
puts nodes.length

when I run that code I have originally 4 nodes, and after, I still have 
4 nodes. I found a way to do this but I disklike it, because it has to 
search for the node every time it needs to erase it.

puts nodes.length
nodes.delete(nodes[0])
puts nodes.length
