Tcl can be used to write 'agent' software - that walks WWW pages, scrapes info from the HTML, and the reformats it for display. I know there was a WebTechnique article on this - anyone have pointers? The Article is from the March 2000 issue of WebTechniques. It is called "Writing Intelligent Web Agents" and can be found at http://www.webtechniques.com/archives/2000/03/schrenk/
.Tcl can be used to write WWW browsers - see Browsex [1] for the latest effort.Tcl comes with an http library, which allows you to write tools to read data rather easily. You do have to find an HTML parsing library. Someone I hope will provide some pointers here to good places to find such things.Notice that Michael Doyle and Hattie Schroeder's BOOK Interactive Web Applications with Tcl/Tk not only focuses on this topic, but includes a complete open-source Tk-coded browserMDD: The source was included on the CD with the book. The examples from the book are available at http://www.eolas.net/tcl/examples/tclbook-examples.zip
Did anyone ever notice the HTML 4.01 reference document's references to Tcl? See http://www.w3.org/TR/html401/interact/scripts.html
!A finer granularity treatment of this topic can be found Using Tcl to write WWW client side applications within the WWW browser; This page would be used to talk about non-browser solutions - I guess web scrapers, embedded html browsers, etc.? [Is that supposed to say "within" or "without"?]
