I wasn't making fun of you.

Sorry, it's "structure" you want to use.

<tal:replace=3D"structure <some tag or other>">

Now, if you are going to generate some complex tag then you are best =20
of doing this in a PythonScript and returning the string to the =20
template. However, I do not think that is the way to want you want as =20=

I this only makes sense for extremely dynamic content. In my view =20
it's better to use standard tags.

Your source is virtually impenetrable to me which I think is a guide =20
to it being wrong.

<span tal:define=3D"r record/name; id record/task_id; mylt
string:'<'; mygt string:'>';"
            tal:replace=3D"string:${mylt}option label=3D'${r}'
value=3D'${id}'${mygt}${r}${mylt}/option${mygt}"></span>

<option tal:attributes=3D"label record/name; value record/task" =20
content=3D"record/value"></option>

No formatting required at all. At least I think that's what you want!
