忽略 biber 中的特定 URL 字段？

忽略 biber 中的特定 URL 字段？

我使用 Biber 来阅读我的文献。通常应该打印出 URL，但有些条目的 URL 很“丑陋”，例如“http://dx.doi.org/...”等等。如果 URL 字段包含特定字符串，是否可以不打印 URL？我不想清理我的 bib 文件，因为也许我想稍后使用所有 URL。

我尝试了 karlkoeller 的建议，但仍然不起作用。为什么以下代码不起作用？

\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map{
      \step[fieldsource=url,
        match=\regexp{dx.doi.org|dl.acm.org(.+)}, null=true
        ]
    }
  }
}

您的解决方案是使用biblatex和biber的sourcemap功能。

将以下代码片段添加到您的序言中。

\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map{
      \step[fieldsource=url, match=\regexp{http://(dx.doi.org/|dl.acm.org/)}, final]
      \step[fieldset=url, null]
      \step[fieldset=urldate, null]
    }
  }
}

您可以通过在 中指定 URL 来扩展要删除的 URL 列表match=\regexp{http://(dx.doi.org/|dl.acm.org/)}。要进行过滤example.com，请编写该行match=\regexp{http://(dx.doi.org/|dl.acm.org/|example.com)}，但您可能match=\regexp{http://(www.)?(dx.doi.org/|dl.acm.org/|example.com)}还应该使用 来捕获www.example.com。

biber使用 Perl 的正则表达式，你可以阅读更多关于它们的内容这里。

如果biber找到匹配项，则url和urldate被清除，否则什么也不会发生。

biber的功能使我们能够对这些 URL 实施更复杂的处理。

以下 MWE 将映射 DOI、稳定的 JSTOR 标识符和 arXiv 链接至适当的doi或eprintfields。如果您不想显示这些内容，只需将doi=false和添加eprint=false到biblatex的选项即可。

上述内容无法正确使用 https 链接。如果replace={}使用 而不是 ， 则会出现所需的行为replace=\regexp{$1}，如下所示：
