regexpatch 和 xpatch 之间的区别

我正在尝试将我的书目条目中的个别名称放入括号中，并尝试使用 (rege)xpatch 功能修补 biblatex bibmacros。

具体来说，我正在尝试修补 bibmacrosname:given-family和name:family-given。

据我所知，regexpatch提供了相同的补丁命令xpatch，另外还提供了正则表达式功能。而且我无法从文档中了解到 的原始命令的语法有任何变化xpatch。但是，与 配合regexpatch使用的补丁xpatch返回了。MWE：undefined control sequenceregexpatch

\documentclass{article}

\usepackage{xpatch}
%\usepackage{regexpatch}

\usepackage[style=authortitle]{biblatex}
\addbibresource{biblatex-examples.bib}

% These patches work with xpatch, but not with regexpatch
\xpatchbibmacro{name:given-family}
    {\usebibmacro{name:hook}}
    {\bibopenbracket\usebibmacro{name:hook}}
    {}{}

\xapptobibmacro{name:given-family}
    {\bibclosebracket}
    {}{}

\xpatchbibmacro{name:family-given}
    {\usebibmacro{name:hook}{#3#1}}
    {\bibopenbracket\usebibmacro{name:hook}{#3#1}}
    {}{}

\xpatchbibmacro{name:family-given}
    {\usebibmacro{name:hook}{#1}}
    {\bibopenbracket\usebibmacro{name:hook}{#1}}
    {}{}

\xapptobibmacro{name:family-given}
    {\bibclosebracket}
    {}{}

\begin{document}

\nocite{*}

\printbibliography

\end{document}

我遗漏了什么或者做错了什么？

注意：我需要其他真正需要正则表达式功能的补丁，并且如果可能的话，为了代码的可读性，regexpatch我愿意使用原始补丁命令。xpatch

您发现了一个隐藏的功能。;-)

这应该可以解决这个暂时的问题。

\documentclass{article}

%\usepackage{xpatch}
\usepackage{regexpatch}

% Fix regexpatch itself
\ExplSyntaxOn
\makeatletter
\exp_args:Nc \xpatchcmd { xpatchbibmacro~code }
 {\xpatch_main:Ncnnnn}
 {\xpatch_main_four:Ncnnnn}
 {}{}
\makeatother
\ExplSyntaxOff

\usepackage[style=authortitle]{biblatex}
\addbibresource{biblatex-examples.bib}

% These patches work with xpatch, but not with regexpatch
\xpatchbibmacro{name:given-family}
    {\usebibmacro{name:hook}}
    {\bibopenbracket\usebibmacro{name:hook}}
    {}{}

\xapptobibmacro{name:given-family}
    {\bibclosebracket}
    {}{}

\xpatchbibmacro{name:family-given}
    {\usebibmacro{name:hook}{#3#1}}
    {\bibopenbracket\usebibmacro{name:hook}{#3#1}}
    {}{}

\xpatchbibmacro{name:family-given}
    {\usebibmacro{name:hook}{#1}}
    {\bibopenbracket\usebibmacro{name:hook}{#1}}
    {}{}

\xapptobibmacro{name:family-given}
    {\bibclosebracket}
    {}{}
