jQuery how to find an element based on a data-attribute value?

I've got the following scenario: ``` var el = 'li'; ``` and there are 5 `<li>`'s on the page each with a `data-slide=number` attribute (number being 1,2,3,4,5 respectively). I now need to find the currently active slide number which is mapped to `var current = $('ul').data(current);` and is updated on each slide change. So far my tries have been unsuccessful, trying to construct the selector that would match the current slide: ``` $('ul').find(el+[data-slide=+current+]); ``` does not match/return anything… The reason I can't hardcode the `li` part is that this is a user accessible variable that can be changed to a different element if required, so it may not always be an `li`. Any ideas on what I'm missing?
