I think you missed the point and an i modifier.

while ( <DATA> )

    print if /\Ahttps.*[^\/]\n\z/;

Gives these which are either completely invalid or "end" with a trailing slash since the fragment and the empty query string are irrelevant to the URI path.

If you know for a fact that your data set is simple/normalized enough, you could use a straightforward regular expression. URI is simple and robust however so not using it is just sloth and it will eventually bite you or the dev who inherits your code. Trusting input data to be well-formed is risky and only appropriate in one-offs.

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.
