How to check for an attribute in a variable-selector using jquery?

Question

I'm having the following Jquery code:

$('div:jqmData(wrapper="true"):jqmData(ex="true") div:jqmData(role="page")').each(function(index) { 
     // do sth 
     });

I want to replace $('div:jqmData(wrapper="true") with my variable page.

Question:
How do I get the above syntax working with my variable page? This is not really working:

page.is(':jqmData(ex="true")').find('div:jqmData(role="page")').each(function() { 
   // do sth 
   });

Thanks for some inputs!

.is returns a boolean indicating whether the selector applies to one ore more elements in the set. To filter the current set, use .filter instead:

page.filter(':jqmData(ex="true")').find(...)

The is function in jquery only return true of false, so you can use it in an if statement like below:

if(page.is(':jqmData(ex="true")'))
{
    page.find('div:jqmData(role="page")').each(function() { 
        // do sth
    });
}
