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

Due to recent job search needs in my family, I've been working on a Perl module that will take a resume in XML format and translate it to a variety of formats. I did some looking around the Internet, but none of the wheels I found were quite the right shape or size for my needs, and I thought it'd be a fun learning project. Right now I have a single object with the following output functions:

  • output_raw - simply uses the toString method to return the raw XML
  • output_html - uses XSLT to transform the XML resume to (X)HTML
  • output_text - uses XSLT to transfor the XML resume to reasonably laid out text, then uses Text::Wrap to wrap long lines to 80 columns
  • output_pdf - the most ambitious, uses XSLT to transform the XML resume into a series of sections and lines that are then fed to PDFLib to generate a PDF file.

My question is this: should I keep this as a single object, or sub-class each output style into a child object. Ie, something like this:

  • Resume - contains the basic functions for importing the XML resume and has an output function that returns the raw XML
  • Resume::HTML - child of Resume that overloads the output function with one that transforms the XML to HTML and returns that
  • Resume::Text - child of Resume that overloads the output function with one that transforms the XML to ASCII text
  • Resume::PDF - contains all of the PDF functions and overloads the output function with one that generates the PDF file

I'm kind of leaning toward this new setup, which I believe leaves me open for future enhancements, but I thought I'd see what the experts have to say. I'd also love to hear any additional features or output formats you think I should add. Once I get more of the code put together, I'll be happy to post it for review.

Title:
Use:  <p> text here (a paragraph) </p>

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).
