Hey Rodrigo, I wanted to shine some more light on the subject of retrieving info from the http request, creating footnotes, headers, summeries, etc., and then presenting the web page.
Another idea, (if you have'nt found one already.) Have a general page anyone can browse to that has the rebol/plug-in tagged in it already. make the plug-in viewable as an address bar and go button. Type in the page you want to go to, and let the plug-in retrieve it, not the browser. ie.. myinfo: read http://www.getmyinfo.com , then parse out the info you need and add or change it with your plug-in script. ie... append myinfo {<footer>tadah</footer>} Save this updated page to your "c:/program files/temp", getinfo: to-file %"/c/program files/temp/cool.html" write getinfo myinfo Then have the rebol/plug-in load this page into the browser. i believe you can make it load into the opened webpage. ie... browse getinfo A suggestion, also input into each newly created page your rebol/plug-in object. That way you dont have to go back to the the original page just to get new or more info. ----- Original Message ----- From: "Rodrigo de Oliveira" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Saturday, April 02, 2005 12:03 PM Subject: [REBOL] Re: Can REBOL change HTML of a web page? > > Well...
