( #3333=superdoc: print w/replies, xml ) Need Help??

Your solution looks very close to a common trick I use, which is to assign a vairable to another variable, then do a regex search and replace on the new one:

my $file = 'file013.txt'; (my $sk = $file) =~ s/^.*?(\d+).*$/$1/;

Which for the sake of this problem is a very similar solution to what others are proposing, the above method is much more useful when I want to keep most of the string rather than a portion of it.

Example, I want to emphasise the word keep above:

my $boring_string = '...when I want to keep most of the string...'; (my $exciting_string = $boring_string) =~ s/(keep)/<b>$1</b>/;

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.
