Question

有人可以告诉我如何使用perl编程语言将rtf文件转换为包含所有标签，表格和格式化数据的文本？

我一直在使用以下代码进行RTF到TXT转换，我可以转换成文本。但问题是我无法捕获表，甚至输入文件中的所有实体都没有使用该程序捕获。

use strict;
use warnings;
use Getopt::Long;
use Pod::Usage;
use RTF::HTMLConverter;

my %opts;

pod2usage(-verbose => 1, -exitval => 0) if $opts{help};

my %params;
if($opts{dom}){
  eval "require $opts{dom}";
  die $@ if $@;
  $params{DOMImplementation} = $opts{dom};
}else{
  eval { require XML::GDOME };
  if($@){
    eval { require XML::DOM };
    die "Can't load either XML::GDOME or XML::DOM\n" if $@;
    $params{DOMImplementation} = 'XML::DOM';
  }
}

}else{
  $params{image_dir} = $opts{imagedir} if defined $opts{imagedir};
  $params{image_uri} = $opts{imageuri} if defined $opts{imageuri};
}
