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

It is pretty difficult to answer you with the litlle information you give us, but I'll try anyway ;--(

If the data is not SGML, XML or HTML I don't think you should try to use SGML/XML/HTML tools on it. SGML and XML tools will simply not accept the data, and HTML tools will try their best, but their guess may not be what you expect.

It really depends on the format of your data files, but I would probably try to first convert the data to XML, using regexps, and then use XML tools which are usually pretty fast. But that's because I am used to processing XML, and my output is usually either XML or HTML, so an XML transformation gives me the result I want.

Also, the problem with your finite state machine may be the tokenizer. If you scan the input one character at a time, C-style, this may not be optimal, tokenizing using regexps may be faster.

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.
