Function Block STR_TRIM

The function block STR_TRIM removes whitespaces (or other characters) from the beginning and end of a string.

Input STR

The input defines the string to be processed.

Input CHARACTER MASK

  • " " (ASCII 32 (0x20)), a normal space.
  • "\t" (ASCII 9 (0x09)), a tab character.
  • "\n" (ASCII 10 (0x0A)), a line feed.
  • "\r" (ASCII 13 (0x0D)), a carriage return.
  • "\0" (ASCII 0 (0x00)), the NUL byte.
  • "\x0B" (ASCII 11 (0x0B)), a vertical tab.

Note: These must necessarily be in double quotation marks.

Output

Returns a string cleaned on both sides.
