[AccessD] SQL to count delimiters in a string

Assume I have a text field in a table. Further assume that the text strings
are delimited by the pipe character "|". I want to know how many pipe
characters occur in each field, ie. the select statement should return:

fldText                         Occurrences
test|ddd|ww|ex                3
fff|sss                             1
eenie|meenie|minie|moe   3

What is the correct SQL to produce the desired result? TIA
