rspec users - Jan 2007 - Best way to specify an HTML element inside another

Hi

I know should_have is preliminary but I can''t resist using it...

I have a form that contains a date select (Rails-generated).  I want  
to specify that the default value for each popup menu is correct

The best I can manage is this:
     response.should_have "form > p >
select[name=''quote_parameters
[purchase_date(3i)]''] >
option[selected=''selected'']", :text =>
''16''

I really want to specify two attributes for the <option> tag, like  
option[selected=''selected'',value=''16''] - is
there any syntax that
allows this?
