This has come up before and it comes up in the classroom.  What you 
need to use here is grouping, creating new groups for every <br> and 
encapsulating everything in the group except <br> elements (which are 
the first in those groups that have a <br> and possibly not present 
in the very first group, as is true with your data).

I hope the working answer below helps.
