Why the string interpolation is not working inside the Nokogiri method `#search` ?

require 'nokogiri'

doc = Nokogiri::HTML::Document.parse <<-eotl <div>   <p>foo</p>   <p>foo</p>   <p>bar</p> </div> eotl

doc.class # => Nokogiri::HTML::Document

class Person   attr_accessor :name end

ram = Person.new ram.name="foo" ram.name # => "foo" doc.search('//div/p[text()= "#{ram.name}"]').to_a.size # => 0

Where am I doing wrong ? please help!

You are not wrapping it in a "" or %Q{}...: 1. doc.search("//div/p[text()= \"#{ram.name}\"]").to_a.size 2. doc.search(%Q{//div/p[text()= "#{ram.name}"]}).to_a.size

@Jordon - Thank you very much - it worked like a charm!!

require 'nokogiri'

doc = Nokogiri::HTML::Document.parse <<-eotl <div>   <p>foo</p>   <p>foo</p>   <p>bar</p> </div> eotl

doc.class # => Nokogiri::HTML::Document

class Person   attr_accessor :name end

ram = Person.new ram.name="foo" ram.name # => "foo" doc.search("//div/p[text()= \"#{ram.name}\"]").to_a.size # => 2
