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

Some thoughts:

  • There is no  || regex operator. More precisely,  || resolves to a pair of  | regex alternation operators with a null pattern between them, and the  // null regex pattern matches everything, so no surprise about the junk.
  • I don't get where the   $tgt  $tgtf  $tgtl variables are defined and initialized: what are these supposed to represent? Do you have any philosophical objection to running with strict and warnings enabled?
  • (Update: The  /c$tgt || c$tgtf || c$tgtl || $tgtf || $tgtl / regex has embedded literal spaces. I don't know if this is intentional, but you may want to investigate the  /x regex modifier; see Modifiers.)

Can you supply a short, representative chunk of the sample input data you wish to process and its desired final form? I think that would help greatly to define the problem.

Update: Various small wording and spelling fixes.

Give a man a fish:  <%-{-{-{-<

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 or How to display code and escape characters are good places to start.
