I'm not sure if my mind is twisted enough! I can follow how Jairo's
answer works, and that does what I need it to, but it's not as clear to
me what the last two TeX-only approaches are doing at a low level.
Perhaps more importantly, I should clarify that for my purposes, the
\MyOuter macro is the \currentbtxrighttext macro, which is defined in a
separate module that I'd prefer not to modify. I want to be able to
detect and parse the parameters of a \loc macro that a user can specify
in a citation as follows:
```
\cite[lefttext={See}, righttext={\loc[vol=8,p=223] for further
details}][clementinehomilies]
```
Because the locator parameters may need to be parenthesized or formatted
differently depending on the category of the bibliography entry, they
should be typeset separately from the plain part of the righttext. This
is why I'd like to be able to parse the parameters and then expand the
\loc macro itself as empty when the righttext is typeset.
in that case: just redefine \loc on the fly depending on where it's used
and/or use keys
\cite[lefttext={See},volume=8,page=223]
or so .. imo parsing content is not really a good solution and probably
also not reliable
