我希望生成内容和日期的两份目录，请问应该如何实现？

试着做了一下

\documentclass{article}
\usepackage{lipsum}

\ExplSyntaxOn

  date .clist_set:N = \l__alfred_date_tl,
  title .tl_set:N = \l__alfred_title_tl
}

{
  \tl_clear:N \l_tmpa_tl
  \clist_map_inline:nn { #1 }
  {

  }
  \tl_set_eq:NN #2 \l_tmpa_tl 
}

\cs_new:Npn \alfred_parse_datefmt:nN #1#2 
{

  {
    \clist_item:nn {#1}{1}-
    \clist_item:nn {#1}{2}-
    \clist_item:nn {#1}{3}
  }
  \tl_set_eq:NN #2 \l_tmpa_tl 
}
