jquery regex replace
===

Never seem to master those regex's...

I need to update the total with newVal

    <span class="myClass">some text Total (12)</span>
into

    <span class="myClass">some text Total (13)</span>

and also without a current value

    <span class="myClass">some text Total</span>

into

    <span class="myClass">some text Total (13)</span>

oh, and some text can be anything

my code

    newVal = 13;
    $('.myClass').text().replace(???, ???)
