String comparisons in IfStatements

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

Are there any possibilites to compare if string

• is contained in another string?
• Starts with some string (http://www.tutorialspoint.com/python/string_startswith.htm)
• Ends with some string (http://www.tutorialspoint.com/python/string_endswith.htm)

I know that I provided examples from Python, but Perl also have more advanced string comparisons possibilites: http://stackoverflow.com/questions/7011524/perl-if-string-contains-text

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
