DeleteCases[list, ___:___] looks very logical and should work, but of course it doesn't . Also, there is a StringCases function which would seem to correspond with the Cases function. There is a DeleteCases function but no string counterpart, namely, DeleteString function. Any reason for this? Thanks in advance.
