Yes, and you have been shown why regexp is the wrong tool for parsing
SGML heritage - especially when there is something as awesome as
Nokogiri around. :-)

require 'nokogiri'

dom = Nokogiri::XML <<XML
<doc><p id="a124">this is a paragraph</p><ul id="b234567"><li
id="a4563">list item</li></ul></doc>
XML

dom.xpath('//*[@id]').each do |node|
  printf "%-10s %s\n", node[:id], node.name
end

Kind regards

robert
