Question

Does anyone know of a simple way one could count and display the number of headings of a certain level(i.e. level 1, level 2, etc) within a topic? I am trying to figure out a simple way to list the number of comments on a topic if all comments were preceeded by a heading of a certain level. Thanks for any thoughts on this.

Answer

Do a multiple="on" search on the topic for the heading, like "\-\-\-\+\+ ", and count the number of hits with the SpreadSheetPlugin. For this you need the latest TWikiAlphaRelease.

Example:

%SEARCH{ "\-\-\-\+\+ " scope="text" topic="%TOPIC%" regex="on" multiple="on" format="|$text|" nosearch="on" nototal="on" }%
| Total: %CALC{$ROW(-1)}% |

produces this on the current topic:

You can hide this table in HTML comments and refer to the total after the commented out table with %CALC{$ROW(-1)}% (gives this: 3)

You can also put the whole thing into a topic you include in other topics (use topic="%INCLUDINGTOPIC%" to point search to the correct topic)

Hope this helps.

Wow! I would have never figured that one out on my own and I'm impressed that there was a way to do it at all. Thanks so much, Peter!
