OK, so you want every tag that is a sibling of address and pre and is
within those two. I have found this StackOverFlow answer:

http://stackoverflow.com/a/6555376

which applied to your problem:

1.9.2p290 :001 > require 'nokogiri'
 => true
1.9.2p290 :002 > s = <<END
1.9.2p290 :003"> <!-- body="start" -->
1.9.2p290 :004"> <div class="mail">
[...snip...]
1.9.2p290 :031 > doc = Nokogiri::HTML(s)
1.9.2p290 :039 >
doc.xpath("//address/following-sibling::node()[count(.|
//pre/preceding-sibling::node())=count(//pre/preceding-sibling::node())]")
 => [#<Nokogiri::XML::Text:0xdb0114 "\n">,
#<Nokogiri::XML::Element:0xdaff84 name="p"
children=[#<Nokogiri::XML::Text:0xdafc28 "\nLine 1\n">,
#<Nokogiri::XML::Element:0xdafa5c name="br">,
#<Nokogiri::XML::Text:0xdaf728 "\nLine 2\n">,
#<Nokogiri::XML::Element:0xdaf5ac name="br">,
#<Nokogiri::XML::Text:0xdaf228 "\nLine 3\n">,
#<Nokogiri::XML::Element:0xdaf0ac name="br">]>,
#<Nokogiri::XML::Element:0xdaea80 name="p">]

will return a node set that contains the required nodes.

Hope this helps,

Jesus.
