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

I think a better idea is to use a tied hash as the basis of your class in testing and development, and an untied hash in production release. This way you bypass the requirement for converting from method syntax to hash syntax using a regex. All attributes of the objects are accessed via hash notation. The tie ensures that the keys and values are legal, etc. Then when you switch out of development/test mode, you disable the tie and get the speed benefit of pure hash accesses. You could even selectively enable the tie as required.

I believe that Damian Conway wrote Tie::SecureHash with this in mind, with the added benefit of namespace rules to aid in subclassing. But I think it may also be worth hand coding in some cases.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.

    [ovedpo15]: But I don't know the length of the string. will it still work?
    [ovedpo15]: The only thing I know is that there is a comma at the end and a value after that
    [hippo]: Try it and see. Your computer won't explode.
    [Corion]: length will tell you the length of a string.
    [Corion]: But if you are parsing CSV, again, let me point to Text::CSV_XS, which you should use instead
    [hippo]: +1 for Text::CSV_XS
    [ovedpo15]: Im not allowed to use additional modules, so I can't use it. looking for a simple regex to do this task though..
    [Corion]: Ah, so this is homework? Then most likely, you should review your course material closer. It would greatly surprise me if the course material wouldn't mention the topics that will be used in the homework...
    [Corion]: I already showed you the simple regex to match the last part of a string without a comma in it
    [Tux]: Corion++ hippo++
