Substring

This block extracts part of a string.

Configuration

• Input String: the string to extract from.
• Start Position: zero-based position of the first character to keep.
• Extract: how much to extract.
  • To End of String: everything from the start position to the end of the string.
  • Fixed Length: at most Length characters from the start position.
• Length: number of characters to extract. Only shown when Extract is set to Fixed Length.

Connections

• Result: executed after the extraction. The extracted text is available to the following blocks as result_str.

Note

Out-of-range positions are clamped, so the block never fails. If Start Position is past the end of the input, the result is an empty string.
