How to set up patterns when using SequenceSplit












2















Given a list



lst={0,0,0,0,0,"A1",0,0,0,"B2",0,0,"C3","D4","E5",0,0,0,"F6"}


How to split it as



{{0,0,0,0,0},{"A1",0,0,0},{"B2",0,0},{"C3"},{"D4"},{"E5",0,0,0},{"F6"}}


I want to use SequenceSplit but didn't know how to set up the right pattern.



SequenceSplit[lst, {_String} -> {}]


Thanks!

            @Jerry, in a test function used as the second argument of Split, #1 refers to the first element of a consecutive pair and #2 to the second, See also animation - Split which illustrates how it works for the default test function SameQ.
