如何提取不在环境中但包含定义的命令的一系列文本

Question 1

由于文件创建是自动的，我们可以依靠一致的使用，并利用这一点来获得优势。为此，我

假设你绝不使用\subsubsection*{..}或\subsubsection[.]{..}
假设你会总是\subsubsection{..} ... \clearpage对于任何都有\subsubsection。也就是说，\subsubsection标题后的文本在开头以分隔\subsubsection{..}，在结尾以分隔\clearpage。

\documentclass{article}
\usepackage{xcolor}

\let\oldsubsubsection\subsubsection
\makeatletter
\long\def\subsubsection#1#2\clearpage{%
  \begingroup
  \let\textcolor\@secondoftwo% Extract <text> from \textcolor{<color>}{<text>}
  \let\textsf\@firstofone% Ignore \textsf
  \let\textbf\@firstofone% Ignore \textbf
  %\let\par\space% If \par is a problem in the output
  % ... Ignore other commands
  \xdef\@@x{#2}% Extract entire <title> in \subsubsection{<title>}
  \immediate\write\subsubsectiontextfile{\@@x}% Write <title> to file
  \endgroup
  \oldsubsubsection{#1}#2\clearpage% Regular \subsubsection
}
\makeatother
\AtBeginDocument{%
  \newwrite\subsubsectiontextfile
  \immediate\openout\subsubsectiontextfile=\jobname.sst}
\AtEndDocument{\immediate\closeout\subsubsectiontextfile}

\begin{document}

\section{How to Find and Extract Text within Fixed Markers}

\noindent\rule{150pt}{1.7pt}  
\vspace{2pt}
\subsubsection{\textcolor{blue}{\textsf{R} Note: History and Current Status of \textsf{R}}}:
\textsf{R} is an open source software platform used to analyze data.  
Written originally in the early 1990's, it is an \textbf{object-oriented}, \textbf{interpreted} 
programming language blessed with a wealth of constantly-growing and improving "packages" and 
a vibrant user community.

\clearpage

\section{Each Note is at the bottom of a page.  All have the same start up to Note: They end with clearpage}

\noindent\rule{150pt}{1.7pt}

Some other text. **There are NO OTHER COMMANDS after the colon except \textsf{R} and all of it consists 
of ONE LINE OF TEXT.**

\clearpage

\end{document}

上面产生<jobname>.sst了

: R is an open source software platform used to analyze data. Written originally in the early 1990's, it is an object-oriented, interpreted programming language blessed with a wealth of constantly-growing and improving "packages" and a vibrant user community. \par 
: Some other text. **There are NO OTHER COMMANDS after the colon except R and all of it consists of ONE LINE OF TEXT.** \par

\begingroup...之间的部分\endgroup用于删除文本中可能包含的所有格式。在我们的例子中，它删除了to和和to\subsubsection的功能（在这两种情况下，它们都只返回）。您可以在此处添加更多此类无操作。\textcolor{<colour>}{<text>}\@secondoftwo\textsf{<text>}\textbf{<text>}\@firstofone<text>

一旦提取，我们立即将其写入文件。只需打开此文件然后关闭它<jobname>.sst即可，因为您对它所在的页面不感兴趣。\AtBeginDocument\AtEndDocument

不确定包含是否\par有问题。您可以添加\let\par\space以转换\par为常规空间。

Question 2

如果我们获取原始问题中给出的精确文件（例如，名为myfile.tex），并将其输入sed像这样：

sed -n '/\\subsubsection.*Note:/,/\\clearpage/p' myfile.tex

你将获得以下输出：

\subsubsection{\textcolor{blue}{\textsf{R} Note: History and Current Status of \textsf{R}}}:  \textsf{R} is an open source software platform used to analyze data.  Written originally in the early 1990's, it is an \textbf{object-oriented}, \textbf{interpreted} programming language blessed with a wealth of constantly-growing and improving ``packages'' and a vibrant user community.

\clearpage
\subsubsection{\textcolor{blue}{\textsf{R} Note: Different text}}:  Some other text.  **There are NO OTHER COMMANDS after the colon except \textsf{R} and all of it consists of ONE LINE OF TEXT.**

\clearpage

现在，我们要删除到的部分Note:和的部分\clearpage，这可以通过将其传输到来实现：

sed 's/\\subsubsection.*Note: //g;s/\\clearpage//g'

得出的结果为：

 History and Current Status of \textsf{R}}}:  \textsf{R} is an open source software platform used to analyze data.  Written originally in the early 1990's, it is an \textbf{object-oriented}, \textbf{interpreted} programming language blessed with a wealth of constantly-growing and improving ``packages'' and a vibrant user community.


Different text}}:  Some other text.  **There are NO OTHER COMMANDS after the colon except \textsf{R} and all of it consists of ONE LINE OF TEXT.**

最后，我们要去掉一些TeX东西。将结果通过管道传输到命令detex（TeX Live 的一部分）将会这样做。

把它们放在一起看起来就像这样：

sed -n '/\\subsubsection.*Note:/,/\\clearpage/p' myfile.tex | sed 's/\\subsubsection.*Note: //g;s/\\clearpage//g' | detex

其结果是：

History and Current Status of R:  R is an open source software platform used to analyze data.  Written originally in the early 1990's, it is an object-oriented, interpreted programming language blessed with a wealth of constantly-growing and improving ``packages'' and a vibrant user community.

Question 3

由于是 Windows 8，因此应该包含 PowerShell，但目前我只能轻松访问 Windows 10 进行测试。以下是您可以在 PowerShell 提示符下运行的内容，假设将提取单行字符串。

给定一个源 .tex 文件

\documentclass[11pt]{article}     
\begin{document}
\section{How to Find and Extract Text within Fixed Markers}
\noindent\rule{150pt}{1.7pt}  
\vspace{2pt}
\subsubsection{\textcolor{blue}{\textsf{R} Note: History and Current Status of \textsf{R}}}:  \textsf{R} is an open source software platform used to analyze data.  Written originally in the early 1990's, it is an \textbf{object-oriented}, \textbf{interpreted} programming language blessed with a wealth of constantly-growing and improving "packages" and a vibrant user community.
\clearpage
\section{Each Note is at the bottom of a page.  All have the same start up to Note: They end with clearpage}
\noindent\rule{150pt}{1.7pt}  
\vspace{2pt}
\subsubsection{\textcolor{blue}{\textsf{R} Note: Different text}}:  Some other text.

\end{document}

您可以在 PowerShell 提示符下运行以下命令：

sls'^\\subsubsection'290814.tex`
| 选择 -ExpandProperty 行 `
| foreach { 写入主机 ($_ -split ': ')[1] }

并得到结果

\textsf{R} 是一个用于分析数据的开源软件平台。它最初于 20 世纪 90 年代初编写，是一种 \textbf{面向对象}、\textbf{解释型} 编程语言，拥有大量不断增长和改进的“软件包”以及活跃的用户社区。
一些其他文本。

我绝对不是 PowerShell 专家，但简单的解释是：

sls是的别名select-string，大致相当于 Unix 的grep
该select行从结果行中删除文件名和行号前缀
迭代foreach输出的每一行，按序列分割行:，并返回第二行。
