If information should be grouped by <p>, I'd do a two step approach,
something like this

require 'nokogiri'

dom = Nokogiri.HTML(<<DOC)
<p>
 <span class="label">Name:</span>  PeterPan<br>
 <span class="label">Tag:</span>   Critical<br>
 <span class="label">Priority:</span>  223<br>
 </p>
DOC

dom.xpath('//p').each do |para_tag|
  dat = {}

  para_tag.xpath('span[@class="label"]').each do |span_tag|
    dat[span_tag.text[/\A(.*?):?\z/, 1]] = span_tag.next_sibling.text
  end

  p dat
end

Kind regards

robert
