HTML stands for HyperText Markup Language.
----
html is also a module in the [tcllib] library of tcl code. Its purpose is to aid developers in generating HTML programmatically. Related modules are [ncgi], [javascript],
and [htmlparse].
Documentation can be found at http://tcllib.sourceforge.net/doc/html.html
----
Many with an interest in HTML will want to know about the [HTML widgets] page, which discusses widgets that ''render'' HTML into a visual representation.
----
If only parsing of HTML is required, without rendering, [htmlparse] (a module in [tcllib]) is a possible solution. Other solutions include [tkHTML] compiled for use without Tk, and [tcltidy].
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
[Second European Tcl/Tk Users Meeting] ( http://www.tu-harburg.de/skf/tcltk/tclum2001.pdf.gz ).

A recent posting to comp.lang.tcl contained a really small example - it can be found at http://groups.google.com/groups?hl=en&frame=right&th=56ce65fa7fa8bdec&seekm=a8q1kf%24sg5%241%40bagan.srce.hr#link4
If the task is to 'pull out' some data out of a HTML page, I'm indeed a
strong believer in the 'parse the HTML page into a tree and query that
tree' approach. For real life problems, I claim that this approach is
much simpler and easier to maintain - and for sure, you have to
maintain such a thingy, because the layout of HTML pages tend to change
frequently - than every regexp approach. Sure, you have to learn
another query language - xpath in this case. But if you are really in
the web business, there are chances you have to learn xpath anyway.

If the task is to generate HTML or XML, try xmlgen, a package within
TclXML and found on http://sourceforge.net/projects/tclxml/ .

Can Someone submit a sample example code for using html:: package . I need to know how all functions glue together.I read cgi.tcl based examples. More exactly I am wondering If I need to call html::closetags for closing. That is not the case with cgi.tcl. Because of this lack of info I could not use. I am just new to TCL but appreciate its "power from simplicity" approach. Does html:: really a substitute for cgi.tcl

Some example code from comp.lang.tcl :

Quick taste,
(bin) 15 % package req html
1.1
(bin) 16 % html::textInput first_name
(bin) 17 % html::textInputRow "MY LABEL" test_row
MY LABEL
(bin) 24 % set people {John Doe Mary Poppins Jack {B. Nimble}}
John Doe Mary Poppins Jack {B. Nimble}
(bin) 25 % html::tableFromList $people
John
Doe
Mary
Poppins
Jack
B. Nimble
similarly there's html::tableFromArray, proc html::checkbox etc...
Using the html package with tclhttpd templates makes form/page
generation quite simple;-)
