I wouldn't do that. You are untainting something that should not, IMO, be untainted. Consider an if statement and call the darn method from there. You are definitely asking for trouble with this code.

All someone would have to do is return
'NewDocument($refname);unlink(*);'

and you would wish you hadn't used this shortcut.

Update: Indeed, as noted below, you can only use letters, numbers, and _ or your regex will cast it out like so many demons. Still, there would seem to me to be just a little too much room for an exploit here. IMO, of course.

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.
