Folks,
In fact I need not split into lines after extracting sections, just feed it
into a wikify with html output.
- In this case I want to keep the prefix and its content, so due to
split I have to add the start one back.
- I am not sure why the "!is[blank] is needed but it is.
- by default this handles block sections, inline items like span's could
be handled as well with mode=inline on the wikify?
Based on your comments I have come up with a working solution I plan to
generalise further.
<$list filter="[{NewTiddler}split[<section]splitbefore[</section>
]!is[blank]addprefix[<section ]]" variable=section>
<$wikify name=display-section text="<<section>>" output=html>
<<display-section>>
</$wikify>
</$list>
Source tiddler "NewTiddler"
<section id="example">
;Bank line above
*WIkitext
*Wikt ''text''
</section>
<section id="example2">
;Bank line above
*WIkitext
*Wikt ''text''
</section>
If the sections are identical (unlike above with a change in ID) you only
see it once. ie it is de-duplicated (A Good thing)
Now I have a solution to the original thread,* thanks all.* However the
need to have a real variable feature, I think my example illustrated still
exists, if not for this case.
Regards
Tony
