Is it possible to convert HTML with Nokogiri to plain text? I also want to include
tag.
For example, given this HTML:
Try
Nokogiri::HTML(my_html.gsub('<br />',"\n")).text
Instead of writing complex regexp I used Nokogiri.
Working solution (K.I.S.S!):
def strip_html(str)
document = Nokogiri::HTML.parse(str)
document.css("br").each { |node| node.replace("\n") }
document.text
end
If you use HAML you can solve html converting by putting html with 'raw' option, f.e.
= raw @product.short_description
Nokogiri will strip out links, so I use this first to preserve links in the text version:
html_version.gsub!(/<a href.*(http:[^"']+).*>(.*)<\/a>/i) { "#{$2}\n#{$1}" }
that will turn this:
<a href = "http://google.com">link to google</a>
to this:
link to google
http://google.com
Nothing like this exists by default, but you can easily hack something together that comes close to the desired output:
require 'nokogiri'
def render_to_ascii(node)
blocks = %w[p div address] # els to put newlines after
swaps = { "br"=>"\n", "hr"=>"\n#{'-'*70}\n" } # content to swap out
dup = node.dup # don't munge the original
# Get rid of superfluous whitespace in the source
dup.xpath('.//text()').each{ |t| t.content=t.text.gsub(/\s+/,' ') }
# Swap out the swaps
dup.css(swaps.keys.join(',')).each{ |n| n.replace( swaps[n.name] ) }
# Slap a couple newlines after each block level element
dup.css(blocks.join(',')).each{ |n| n.after("\n\n") }
# Return the modified text content
dup.text
end
frag = Nokogiri::HTML.fragment "<p>It is the end of the world
as we
know it<br>and <i>I</i> <strong>feel</strong>
<a href='blah'>fine</a>.</p><div>Capische<hr>Buddy?</div>"
puts render_to_ascii(frag)
#=> It is the end of the world as we know it
#=> and I feel fine.
#=>
#=> Capische
#=> ----------------------------------------------------------------------
#=> Buddy?
