StringDelete

StringDelete["string",patt]

yields the string obtained by deleting from string all occurrences of anything matching the string pattern patt.

StringDelete[patt]

represents an operator form of StringDelete that can be applied to an expression.

Details and Options

  • The string expression patt can contain any of the objects specified in the notes for StringExpression.
  • Setting the option IgnoreCase->True makes StringDelete treat lowercase and uppercase letters as equivalent.
  • StringDelete[patt][expr] is equivalent to StringDelete[expr,patt].
  • StringDelete[BioSequence["type","seq"],patt] removes cases of patt in the string "seq" yielding a BioSequence result. In this case, degenerate letters in patt are interpreted as wildcard patterns based on the type of bio sequence. Use Verbatim["patt"] to match degenerate letters literally.
  • If the bio sequence operated upon by StringDelete is circular, wraparound matches are possible.
