How do I determine which buttons are enabled in iOS UI Automation?

Question

Using the UI Automation instrument, I know how to test if a particular button is enabled in my iOS application:

if( btn[0].isEnabled() ) {
    UIALogger.logPass("button enabled");  
} else  {
    UIALogger.logFail("button not enabled");  
}

However, I'd like to be able to determine the number of buttons that have been enabled in the interface, not just whether a specific one is enabled. How could I determine the number of enabled buttons?

Also, how do I print details of these buttons to the console?

Here's a function which takes a UIAElementArray (ie app.mainWindow().buttons()) and logs the number of enabled buttons:

function printEnabledButtons(list) {
    var enabledButtons = 0;
    for (var i=0;i<list.length;i++) {
        if (list[i].isEnabled()) {
            //UIALogger.logDebug("button " + list[i].name() + " is enabled");
            enabledButtons++;
        } else {
            //UIALogger.logDebug("button " + list[i].name() + " is not enabled");
        }
    }
    UIALogger.logDebug("number of enabled buttons: " + enabledButtons);
}

Example calling code:

printEnabledButtons(app.mainWindow().buttons());
