( [id://3333]=superdoc: print w/replies, xml ) Need Help??
I'm trying to solve the following problem with a regex, and so far I have not been successful. I've mostly resigned myself to solving it without a regex, but I'd like to know if anyone here can come up with a clever solution.

I have a potentially malformed URL. It MAY be missing some of the leading characters of the "http://". That is, it might be tp://www.foo.com/ or ://www.foo.com; then again, it might be fine.

I am trying to determine WHAT I need to supply to the beginning of it. I know I could just do a check for ^http://, ^ttp://, ^tp://, and so on, but that seems so barbaric. Any ideas?

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



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
