[jQuery] Doubts on Multiple selection employment

As stated in your documentation, it's possible to iniciate the
selector with more than one filter of "^=" kind. But when I try to use
that feature it doesn's seem to work. Should it work that way? May I
actually use two or more filters of that kind (^=) in the same
expression?
var procsGrid = $("#GridProcedimentos tr[id^='jnGridRow']
[id^='Grid_Linha'][id!='jnGridRowEmpty']");
