perl - 使用 Perl 和 Win32::OLE，如何将 Word 文档中的编号列表转换为纯文本？

Question

我编写了一个 Perl 脚本来使用 Win32::OLE 读取 Microsoft Word 文档内容.

我的问题是文档包含编号列表(以 1、2、3、... 开头)。我的 Perl 脚本无法获取该数字。我只能获取文本内容，不能获取数字。

请建议如何将该编号列表转换为纯文本，同时保留编号和文本。

我的博文Extract bullet lists from PowerPoint slides using Perl and Win32::OLE 演示如何使用 PowerPoint 执行此操作。事实证明，使用 Word 可以更简单地完成任务。

#!/usr/bin/env perl

use strict;
use warnings;
use feature 'say';

use Carp qw( croak );
use Const::Fast;
use Path::Class;
use Try::Tiny;
use Win32::OLE;
use Win32::OLE::Const ('Microsoft.Word');
use Win32::OLE::Enum;

$Win32::OLE::Warn = 3;

run(@ARGV);

sub run {
    my $docfile = shift;
    # Croaks if it cannot resolve
    $docfile = file($docfile)->absolute->resolve;

    my $word = get_word();
    my $doc = $word->Documents->Open(
        {
            FileName => "$docfile",
            ConfirmConversions => 0,
            AddToRecentFiles => 0,
            Revert => 0,
            ReadOnly => 1,
        }
    );
    my $pars =  Win32::OLE::Enum->new($doc->Paragraphs);

    while (my $par = $pars->Next) {
        print_paragraph($par);
    }
}

sub print_paragraph {
    my $par = shift;
    my $range = $par->Range;
    my $fmt = $range->ListFormat;
    my $bullet = $fmt->ListString;
    my $text = $range->Text;

    unless ($bullet) {
        say $text;
        return;
    }

    my $level = $fmt->ListLevelNumber;
    say ">" x $level, join(' ', $bullet, $text);

    return;
}

sub get_word {
    my $word;

    try { $word = Win32::OLE->GetActiveObject('Word.Application') }
    catch { croak $_ };

    return $word if $word;

    $word = Win32::OLE->new('Word.Application', sub { $_[0]->Quit });
    return $word if $word;

    croak sprintf('Cannot start Word: %s', Win32::OLE->LastError);
}

给定以下 Word 文档:

它生成输出:

This is a document>1. This is a numbered list>2. Second item in the numbered list>3. Third oneBack to normal paragraph.>>a. Another list>>b. Yup, here comes the second item>>c. Not so sure what to put here>>>i. Sub-item

Object Browser是不可或缺的。
