customize current _page_item

I have been messing around with the classes.php (Line 567) for a while now.

I’m trying to get it so when your not on the current page the other

• items do NOT have a class at all, so they just look like

instead of <li class=”page_item page_item 1924″>. I know how to hide the page_item page_item 1924 part, but I’m still left with an empty class name when you look at the “view source” code in the browser (<li class=””>)

How do I make it show NO class name at all when it’s not the current page?

Thanks

And how would I put this in my themes function.php file?
