Making the output of a filter into the parameter of another

[Miguel Miranda]

Hi everyone!

I'm having some trouble understanding exactly how to make several filters in a row. I'm having trouble making the output of a filter into the parameter for another. For example, I'd like filter [tags[TiddlerA]] and make that the input of tagging[]. So if we have:

TiddlerA: Tagged as N1,N2,N3.

TiddlerB: Tagged as N2,N3.

TiddlerC: Tagged as N3.

So [tags[TiddlerA]]=[N1][N2][N3]

and I want that to be the input to tagging, so its output would be TiddlerA,B and C.

The thing is I want to put the result into a variable, such as:

    <$vars  test=""" [tagging[tags[TiddlerA]]]""">      ------->Knowing full well the expression is wrong. Do I have to create a previous variable that contains [[tags[TiddlerA]] and then operate on that?

    </$vars>

Thanks!

Perhaps:

<$set name="mylist" filter="[title[TiddlerA]tags[]tagging[]]">
<<mylist>>
</$set>
