如何解析文件以提取“组号”中保存的 3 位数字

我正在编写一个 shell 脚本来解析从标准化 pdf 文件中提取的文本文件。我想为每个测试组（由组 0、组 1... 标识）获取测试编号列表，例如组 0 的 101、102、412...。我尝试过 sed、awk，但我确实这样做理想情况下，我希望将输出转换为 LaTeX 代码，即每个输出项都由合适的字符串包围，例如

\section{Group0}
\Testdetails{101}
\Testdetails{102}
...............
\section{Group1}
\Testdetails{305}
................

这是源文件。

                                                Table 6

答案1

awk '
    $1 == "Group" {printf("\\section{%s%d}\n", $1, $2); next}
    {for (i=1; i<=NF; i++) 
        if ($i ~ /^[0-9][0-9][0-9]$/) {
            printf("\\Testdetails{%d}\n", $i)
            break
        }
    }
'

根据评论更新：

awk '
    $1 == "Group" {printf("\\section{%s %d}\n", $1, $2); next}
    {
      title = sep = ""
      for (i=1; i<=NF; i++) 
        if ($i ~ /^[0-9][0-9][0-9]$/) {
          printf("\\subsection{%s} \\Testdetails{%d}\n", title, $i)
          break
        }
        else {
          title = title sep $i
          sep = FS
        }
    }
'

perl使用regexp和假设的一种方法infile是您在问题中发布的内容。

内容script.pl：

use warnings;
use strict;

while ( <> ) { 
    chomp;
    if ( m/\A\s*(Group)\s*(\d+)/ ) { 
        printf qq[\\Section{%s}\n], $1 . $2; 
        next;
    }   

    if ( m/\s(\d{3})(?:\s|$)/ ) { 
        printf qq[\\Testdetails{%s}\n], $1; 
    }   
}

像这样运行它：

perl script.pl infile

具有以下输出：

\Section{Group0}                                      
\Testdetails{101}                                      
\Testdetails{102}                                      
\Testdetails{412}                                      
\Testdetails{206}                                      
\Testdetails{207}                                      
\Testdetails{201}                                      
\Testdetails{202}                                     
\Testdetails{408}                                      
\Testdetails{101}                                      
\Section{Group1}                                      
\Testdetails{305}                                     
\Testdetails{101}                                     
\Testdetails{324}                                     
\Testdetails{206}                                      
\Testdetails{207}                                        
\Testdetails{410}
\Testdetails{409}
\Testdetails{420}
\Testdetails{426}
\Testdetails{101}
\Section{Group2}
\Testdetails{409}
\Testdetails{305}

为了完整起见，这里有一个sed版本：

sed -n -e 's#^ *Group \([0-9]\+\).*#\\Section{Group\1}#p' \
       -e 's#.*\b\([0-9][0-9][0-9]\)\b.*#\\Testdetails{\1}#p'
