This problem sounds like it suffers from a "Lack of Specification". You indicate that you want to convert back and forth from plaintext to HTML. However, there's a reason why there's two formats - they do different things. I ran into this when attempting to design a Document::Template that would handle PDF, Excel, and other formats. PDF and Excel are sufficiently different that it makes no sense, and HTML is even worse. A better question would be How can I convert a HTML table into fixed-width columns and back again? This is an easily solvable problem. (I could have a solution in 20 minutes and under 250 characters ... golf, anyone?)

Now, mentioning PDF brings up another idea - there are HTML => PDF converters and PDF => plaintext converters. There are also plaintext => PDF converters, but no PDF => HTML converters (that I'm aware of). A big problem with converting from XXX => HTML is that HTMl is a non-deterministic format. I find it easier to consider HTML a "hinting format" instead of a "defining format" (like PDF). Browsers, to be compliant, are free to implement whatever they want, so long as they implement something. (This is how you have HTML-x compliant browsers for the blind.)

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • Outside of code tags, you may need to use entities for some characters:
            For:     Use:
    & &amp;
