如果与期刊匹配，则删除短期刊字段（BibLaTeX 和 biber）

我正在对从 Bookends 导出的文件使用biber和。这种方法大部分情况下都很好用。不过，我有一些期刊文章，由于各种原因，它们的和字段最终都相同。我想做一个地图，检查和是否相同，如果相同，则省略该字段。BibLaTeX.bibjournalshortjournaljournalshortjournalshortjournal

以下是示例条目：

@Article{Larsen1977,
author = {Larsen, Mogens Trolle}, 
title = {Partnerships in the Old Assyrian Trade}, 
journal = {Iraq}, 
shortjournal = {Iraq}, 
volume = {39}, 
number = {1}, 
pages = {119--145}, 
year = {1977}}

理想情况下，应该在导出端修复此问题.bib。根据您的实际使用情况，shortjournal可能根本不需要消除这些情况。

这是一个可以做到这一点的源图，

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[backend=biber, style=authoryear]{biblatex}

\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map{
      \step[fieldsource=journal, fieldtarget=journaltitle]
    }
    \map{
      \step[fieldsource=journaltitle, match=\regexp{\A(.*)\Z}, final]
      \step[fieldsource=shortjournal, match=\regexp{\A$1\Z}, final]
      \step[fieldset=shortjournal, null]
    }
  }
}

\begin{filecontents}{\jobname.bib}
@article{Larsen1977,

  title        = {Partnerships in the Old Assyrian Trade}, 
  journal      = {Iraq}, 
  shortjournal = {Iraq}, 
  volume       = {39}, 
  number       = {1}, 
  pages        = {119--145}, 
  year         = {1977},
}
@article{test2,

  title        = {A Tremendously Interesting Idea},
  journal      = {Journal of Tremendously Interesting Ideas},
  shortjournal = {JTII},
  volume       = {1},
