我正在尝试使用 tex4ebook 生成 .epub。我定义的命令之一使用 \ifelsethen 和 \isempty 来检查空参数，并根据存在的参数产生不同的输出：
- 如果第一个参数为空，则应该打印“empty1”。
- 如果第一个参数不为空，但第二个参数为空，则应该打印“parameter#1 empty2”。
- 如果两个参数都存在，则应该打印两个参数。
我还需要能够向任一参数添加脚注，并且我使用 biblatex 来处理引用。但是，如果我使用 biblatex，此命令将无法正常工作，如下面的 mwe 所示。如果您能提供任何有关如何使 xifthen 函数与 biblatex 配合使用的提示，或者有关与 biblatex 兼容的 \ifthenelse 和 \isempty 替代方案的建议，我将不胜感激。
麦格
\documentclass{book}
%\usepackage{biblatex}
\usepackage{xifthen}
\newcommand{\printif}[2]{\ifthenelse{\isempty{#1}}{empty1}{#1\ifthenelse{\isempty{#2}}{ empty2}{ #2}}}
\begin{document}
\printif{apple\footnotemark[1]}{orange}
\printif{pear}{peach}
\footnotetext[1]{This is a footnote.}
\end{document}
如果我不导入 biblatex，mwe 中的两个示例都会按预期工作。
如果我导入 biblatex 并注释掉第一个示例，文档会编译，但输出不正确：第一个参数和如果第一个参数为空则应该打印的文本都存在于 .epub 中。
