mehrere Autoren (Namen) von \textcites als Possessivpronomen

Question

Erweiterung der früheren Antworten unterAutorenname von \textcite als Possessivpronomen, ich frage mich, wie man den vorgeschlagenen Code anpassen kann, sodass, WENN das Autorenfeld des vorletzten zitierten Eintrags mehrere Namen enthält, das nachfolgende „und“ (um die verschiedenen Einträge abzugrenzen) „schön“ durch z. B. ein „sowie“ ersetzt wird.

\begin{filecontents*}{database.bib}
    @book{texbook,
    author  = {Donald E. Knuth and Someone Else},
    title   = {The {{\TeX}book}},
    publisher   = {Addison-Wesley},
    date    = {1984}
    }

    @inproceedings{foo,
      author = {Foo Bar and {Yet Another} Person},
      title = {Some article},
      abstract = {Here is the abstract.},
      crossref = {acl2015},
      year = {2015}
    }
\end{filecontents*}

und in der Tex-Datei würde ich verwenden wollen

\posscites{foo}{texbook}

und das sollte gedruckt werden als

 Knuth and Else's (1984) as well as Bar and Person's (2015)

Es folgt ein nicht ganz minimaler MWE

I would like the final case, #, to result in:

That is, for the case of british english.

Answer 1

Sie müssen lediglich eine aswellasBibliografiezeichenfolge (mit Definitionen) hinzufügen und dann die Definition von ändern, sodass vor dem abschließenden Zitat anstelle von das Trennzeichen \textcitedelimverwendet wird , wenn das abschließende Zitat mehr als einen Namen enthält.aswellasand

Fügen Sie der Präambel Ihres MWE oben Folgendes hinzu:

\NewBibliographyString{aswellas}
\DefineBibliographyStrings{english}{%
  aswellas = {as well as}
}
\DefineBibliographyStrings{ngerman}{%
  aswellas = {sowei}
}
\renewcommand*{\textcitedelim}{%
  \iffinalcitedelim
    {\ifnumgreater{\value{textcitetotal}}{2}
       {\iftextcitepunct{\finalandsemicolon}{\finalandcomma}}{}%
     \addspace
     \ifnumgreater{\value{labelname}}{1}
       {\bibstring{aswellas}}
       {\bibstring{and}}}
    {\iftextcitepunct{\addsemicolon}{\addcomma}}%
  \space}
