I don't know about the status of this project, but I found this when I
was looking for an existing library that would allow users to enter
simple 'wiki markup' instead of HTML for exactly this sort of scenario
- where you want to give some limited control over the formatting of
user-supplied text.
http://www.radeox.org
I haven't done much with it - but when I was investigating this I
found it pretty easy to integrate in to a WebObjects application. I
just wrote a java.text.Format subclass that used the Radeox API to
format the wiki mark-up to HTML.
Here's my 'format' method (RenderContext and RenderEngine are Radeox
classes):
public StringBuffer format(Object obj, StringBuffer toAppendTo,
FieldPosition pos) {
RenderContext context = new BaseRenderContext();
RenderEngine engine = new BaseRenderEngine();
String formattedText = engine.render(obj.toString(), context);
toAppendTo.append(formattedText);
return (toAppendTo);
}
I then used an instance of my custom java.text.Format as the
'formatter' for any WOStrings that were displaying the user-submitted
wiki-markup.
I'd be interested to know if anyone else has taken this approach and
can recommend any other wiki-markup-to-HTML libraries.
Cheers,
Jake

Hi everyone,
Sorry if this is a really n00b question, but what do you use to
parse input for html tags? Is there anything built in? I'm
using WO 5.3.3 and Wonder.
Thanks!
What is it you want to do?
Chuck
Well, I have a WOText for user input that will be displayed once it
is saved... think: typical weblog.
Ideally, I'd like to allow a handful of html elements so that my
users can have line breaks, paragraphs, and not just a solid block
of text. At the same time, I'd also like to allow class attributes
so that certain elements can be styled for different uses... like a
shell code div, or a paragraph with a drop cap at the beginning.
Naturally, I want to strip out mismatched tags so they can't escape
their own little area on the page, strip out scripts, and pretty
much anything else that could be easily abused. Basically,
whitelist a few things and strip out everything else :-)
You might want to look into using a Textile engine. Quite simple to
use.
with regards,
