HTMLタグで囲まれていない各テキストノードを取得するためのxpathがあります。代わりに、 で区切られてい<br>ます。<span>これらをタグで囲みたいと思います。

Nokogiri::HTML(open("http://vancouver.en.craigslist.ca/van/swp/1426164969.html"))
.xpath("//br/following-sibling::text()|//br/preceding-sibling::text()").to_a

それらのテキストノードを返します。

以下の完全な改訂コード：

doc = Nokogiri::HTML(open("http://vancouver.en.craigslist.ca/van/swp/1426164969.html"))
.xpath("//br/following-sibling::text()|//br/preceding-sibling::text()").wrap("<span></span>")
puts doc

これらのテキストがタグでラップされた完全な html ソース コードが表示されることを期待していました<span>が、次のようになりました。

This is a spectacular open plan 1000 sq. ft. loft is in a former Canada Post building. Upon entering the loft from the hallway you are amazed at where you have arrived.... a stunning, bright and fully renovated apartment that retains its industrial feel. The restoration of the interior was planned and designed by a famous Vancouver architect.
The loft is above a police station, so youÂre guaranteed peace and quite at any time of the day or night.
The neighborhood is safe and lively with plenty of restaurants and shopping. ThereÂs a starbucks across the street and plenty of other coffee shops in the area.  Antique alley with its hidden treasures is one block away, as well as the beautiful mile long boardwalk. Skytrain station is one minute away (literally couple of buildings away). 15 minutes to Commercial drive, 20 minutes to downtown Vancouver and Olympic venues.

doc 変数がドキュメント全体に割り当てられていません — 使用する必要があります

doc = Nokogiri::HTML(open("http://vancouver.en.craigslist.ca/van/swp/1426164969.html"))
doc.xpath("//br/following-sibling::text()|//br/preceding-sibling::text()").wrap("<span></span>")
puts doc

残念ながら、nokogiri は次のようなテキストですべてのスパンよりもすべての br を最初に配置するため、問題は解決しません。

<br><br><br><br><span>
text</span><span>
text</span><span>
text</span><span>
text</span>

しかし、あなたはこのようにすることができます

doc = Nokogiri::HTML(open("http://vancouver.en.craigslist.ca/van/swp/1426164969.html"))
doc.search("//br/following-sibling::text()|//br/preceding-sibling::text()").each do |node|
  node.replace(Nokogiri.make("<span>#{node.to_html}</span>"))
end
puts doc
