Subject: Re: libhxml Node#remove! kills each loop and extension to #<<

PS: Here's another alternative that might work: use delete_if to
iterate and delete those elements you want to get rid of.

 root.delete_if do |node|
   if XML::Node === node
     node.content = "yep"
     node['id'] == "b"
   else
     false
   end
 end

Cheers
