You've posted no code, why make people guess what $htmldata is? You don't show us how you read this input, what processing is done on the input or how you display your output. If all you do is read the data into a variable and print it within a webpage it isn't going to display in the same manner it did within your text editor. You need to learn about HTML, and basic perl. Rather than have to reiterate your problem consider putting some thought into your posts, and asking a real question, How do I post a question effectively?.
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:
Outside of code tags, you may need to use entities for some characters:
- 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
