The benchmark is getElementById().getElementsByTagName() - why not
inlcude that in the test?  Add the following below test 3:


// Test # 4
start = new Date();
$Test = document.getElementById('div' +
            myDiv).getElementsByTagName('p');
end = new Date();
a_Selectors.push('getEBI().getEBTName()');
a_Times.push(end - start);
