Question

I have the following XML for example:

<?xml version="1.0"?>
    <extraslist>
        <extra 
            id="0"
            enabled="1"
            quantityavailable="2"
            displayindex="1">
            <extraname>Example 1</extraname>
            <extradesc>Example 1 Description</extradesc>
        </extra>
        <extra 
            id="1"
            enabled="1"
            displayindex="2">
            <extraname>Example 2</extraname>
            <extradesc>Description 2</extradesc>
        </extra>
    </extraslist>

And a .find function that finds each extra and displays the result on a web page.

$(xmlExtras).find('extra').each(function(){

});

How would I go about writing a function so that if all ‘extras’ = enabled=”0″ to do something…

Update after reading question properly

You can check the length of the find result using an extra selector:

var $enabledExtras = $(xmlExtras).find('extra[enabled="1"]');

if ($enabledExtras.length == 0) {
    //do something
}
