Rails - Sep 2013 - Why the string interpolation is not working inside the Nokogiri method `#search` ?

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
