if you can use jquery,

you can parse this by using $.parseXML

xmlDoc = $.parseXML( "<xml></xml>" );

and then you can use find to get the prefered node

$(xmlDoc).find("roster")

and get number of children via

.children().length

putting it together

var rostersChildren = $(xmlDoc).find("roster").children().length;
console.log(rostersChildren > 0);

here is a sample fiddle.
