What's the proper way to select a nested div with jquery? My specific example looks like this:

<div id="reportTitle">

   <div id="line1">

   <div id="line2">

</div>

I need to set the values of line1 and line2 of reportTitle. I want to make sure that I don't set the value of some other line1 and line2 elements on the page. So I'm looking for something like this:

$('#reportTitle > line1').text('test1')

$('#reportTitle > line2').text('test2')

What's the proper way to do this?
