Get XML attribute value

This is my XML:

<response errors="0"><person><middlename/><name>Egor</name><carsList><car default="true">0777AD</car></carsList><surname>Petrov</surname></person><funds>505.56</funds></response>

I need to get the value of the default attribute for the <car> element.

I found some solutions on Stack Overflow with attr() and attributue() but I had no success using them.

My code is:

unless @account.xpath("//person//carslist").blank?
  @account.xpath("//person//carslist").each do |car|

    p car.attribute('default')

  end
end

On my console I see nil but need to see true.

The correctly variant is:

unless @account.xpath("//person//carsList/*").blank?
  @account.xpath("//person//carsList/*").each do |car|

    p car.attribute('default').content

  end
end

What can it be?

You want:

unless @account.xpath("//person//carsList/*").blank?

Notice the capital 'L' in carsList instead of carslist. Also note the /* to get the child nodes of carList.

The corrected code would be:

  unless @account.xpath("//person//carsList/*").blank?
    @account.xpath("//person//carsList").each do |car|

      p car.attribute('default')

    end
  end
