RE: Text markup for web forums, eg. [b]bold text[/b]

Using "translate(translate(value, '[', '<'), ']', '>')" was one of the
things I thought of. But even if I did the escaping, this does not check the
correctness of the "tags" or guarantee I get well formed / valid (X)HTML.


Scenario 1 (Good Input)
=======================
XML (input):

  <text>
    <value>Text may contain [b]bold text[/b], [i]italics[/i] or both
[b][i]bold and italics[/i][/b].</value>
  </text>

(X)HTML (desired output):

  <div class="text">Text may contain <b>bold text</b>, <i>italics</i> or
both <b><i>bold and italics</i></b>.</div>



Scenario 2 (Bad Input)
======================
XML (input):

  <text>
    <value>[b]blah blah [b][i]blah blah[/b][/i]</value>
  </text>

(X)HTML (desired output):

  <div class="text"><b>blah blah [b][i]blah blah</b>[/i]</div>

I would like to leave non-matching / badly-nested "tags" alone, so they will
be visible to users and alert them to fix the input (this is for a forum
after all).


Regards,
Daniel

In rethinking through this and then testing it it occured to me that this
solution creates some issues with output escaping.  Ive got to attend to
some other things this morning but will take a look at this again later.

Best regards,
