Hi Rodrigo,
I don't know exactly what you are needing but the
Rebol/plug-in can be used to retrieve data from
the web-page and based on your rebol script, it
can be processed as needed.
There are many ways to do this and without CGI
scripts. But what the Rebol/Plugin brings is the
ability to act as a full blown webpage server.
Remember the plugin is limited to IE-Mozilla-Firefox,
and there is no limit to what this plugin can achieve
or do to or from a single webpage. (security issue)
The trick is you must use javascript with XML-DOM (DHTML)
or the .innerHTML (easier) functions to get the page's data.
Look at the Rebol/Plugin webpage for an idea how to do this.
Put this javascript in your rebol script and the rebol script
in the rebol/plug-in code. When the plug-in loads, have the
javascript part inserted into the webpage.
How?
Give each webpage a "<script>" tag with an ID name. ie..
<script id="update"></script>, and this is where you want
the rebol/plug-in to put the javascript.
You can read or write to the page or anywhere else that you
need the returned data to go to.
How do i get Rebol to respond to get new data from the page?
Just like a form has a submit button, you can make the Rebol/
plugin viewable as a button with text that says something like
"update/retrieve data". just and idea.
Another way is to just have regular javascript code in your page
write all your needed info into the DOM, (Document object model)
and then use a Rebol script (maybe quickparser.r at Rebol.org? )
in the plugin to parse the needed data right out of the page and do
with it as you please.
