#!/usr/bin/ruby
require 'nokogiri'
# require 'irb'
text = <<HTML
<html>
<head>
<title>My Title</title>
</head>
<body>
<h1>My Heading</h1>

<!-- body="start" -->
<p>
text line 1
<br>
text line 2
<br>
text line 3
<br>
<p><pre>
very important text
more important text
would you believe even more important text?
</pre>
<p><!-- body="end" -->
not to print
</body>
</html>
HTML
dom = Nokogiri.HTML(text)
puts dom.xpath('/html/body//pre/text()')
puts '---'
puts dom.xpath('//text()[contains(preceding::comment(),"start") and
contains(following::comment(),"end") and not(ancestor::pre)]')
