( #3333=superdoc: print w/replies, xml ) Need Help??
That wouldn't work if the sub is AUTOLOADED, and the package doesn't redefine 'can' to reflect this. (I've seen many packages using AUTOLOAD that don't redefined 'can').

Having said that, and given the fact the subname comes from some XML document whose creation may not be under our control, I would neither use eval, nor a symref, and not can either. I'd make a dispatch table allowing only values I approve of.

my $style = ... retrieve from XML document ... my $value; given ($style) { when ("sub1") {$value = sub1} when ("sub2") {$value = sub2} ... default {die "Illegal style '$style'"} } Wx::TextCtrl->new( $self, -1, "", [5, 10], [-1, -1], $value);

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.
