I am really sorry to say this, but have you even bothered to get and look into Jeffrey Friedl's Mastering Regular Expressions? You have asked a lot of similar questions along the lines of "I want to do this, please tell me how to do it".
The Monastery is a place for you to learn something by looking at the answers of specific questions, but is by no means a substitute for a good Perl/RegEx book or a tutorial. Browse through the Tutorials section. Have a look at the book reviews. And consider starting a new thread when you are asking a question that is not related to the thread you are replying to, especially if you are replying to a post that is already 56 days old.
Sorry if this was a bit harsh, but this is how I feel and I suppose I should at least inform you about it.
Have a nice day.
Cheers,
CombatSquirrel.

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!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • 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, details, 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, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
