String comparisons in IfStatements

In IfStatements I can't find examples of more advanced string comparisons.

Are there any possibilites to compare if string

I know that I provided examples from Python, but Perl also have more advanced string comparisons possibilites:

IF Statements in TML are very limited. You could extend this however by using the %CALCULATE% macro of the SpreadSheetPlugin to do some of the string manipulation.
  • %CALCULATE{$FIND(tion,%TOPIC%)}% evaluates to: 5
  • %CALCULATE{$LEFTSTRING(%TOPIC%,8)}% evaluates to: Question
  • %CALCULATE{$RIGHTSTRING(%TOPIC%,4)}% evaluates to: 1696

So considering the inside-out left-right rendering, you can combine these:
  • %IF{"%CALCULATE{$FIND(tion,%TOPIC%)}%=5" then="'tion' found in position 5"}%
  • 'tion' found in position 5
