I have an XML document:
<cred>
<login>Tove</login>
<pass>Jani</pass>
</cred>
My code is:
require 'nokogiri'
require 'selwet'
context "parse xml" do doc = Nokogiri::XML(File.open("test.xml"))
doc.xpath("cred/login").each do
|char_element|
puts char_element.text
end
should "check" do
Unit.go_to "http://www.ya.ru/"
Unit.click '.b-inline'
Unit.fill '[name="login"]', @login
end
When I run my test I get:
Tove
0
But I want to insert the parse result to @login
. How can I get variables with the parsing result? Do I need to insert the login
and pass
values from the XML to fields in the web page?
I'd use something like this to get the values:
require 'nokogiri'
doc = Nokogiri::XML(<<EOT)
<cred>
<login>Tove</login>
<pass>Jani</pass>
</cred>
EOT
login = doc.at('login').text # => "Tove"
pass = doc.at('pass').text # => "Jani"
Nokogiri makes it really easy to access values using CSS, so use it for readability when possible. The same thing can be done using XPath:
login = doc.at('//login').text # => "Tove"
pass = doc.at('//pass').text # => "Jani"
but having to add //
twice to accomplish the same thing is usually wasted effort.
The important part is at
, which returns the first occurrence of the target. at
allows us to use either CSS or XPath, but CSS is usually less visually noisy.
