使用Perl将RTF转换为TEXT [英] RTF to TEXT conversion using perl
问题描述
有人可以告诉我如何使用perl编程语言将rtf文件转换为带有所有标签,表和格式化数据的文本吗?
Can somebody tell me how can we convert the rtf file into text with all the tags, tables and formatted data using perl programming language ?
@Ahmad Bilal,@petersergeant:我一直在使用以下代码进行RTF到TXT的转换,并且我能够将其转换为文本.但是问题是我无法捕获表格或图像格式,甚至无法使用该程序捕获输入文件中的所有实体.
@Ahmad Bilal , @petersergeant : I have been using the below code for RTF to TXT conversion and i am able to convert into text. But the problem is i am unable to capture table or image formats and even all the entities in the inputfile are not captured using the program.

use strict;
use warnings;
use Getopt::Long;

推荐答案
我是链接模块的作者.不要使用它.如果可能的话,将外壳转换为真正的RTF至文本转换器(如Pandoc).
I am the author of the linked module. Don't use it. If at all possible, shell out to a real RTF to text convertor like Pandoc.
