This is a module in the tcllib library of tcl code. Its purpose is to aid developers in generating HTML programmatically. Related modules are ncgi and javascript.
Many with an interest in HTML will want to know about HTML widgets, which render HTML into a visual representation.
If only parsing of HTML is required, without rendering, htmlparse (a module in tcllib) is a possible solution. As is tkHTML compiled for use without Tk.
Some Tclers advertise tDOM's XPath-oriented parser as desirable for HTML work. This seems particularly popular among European brethren. Note Jochen Loewer's report on his eBay Web scraping at the First European Tcl/Tk Users Meeting (http://www.tu-harburg.de/skf/tcltk/tclum2001.pdf.gz ).
