Perhaps this library can help: https://github.com/google/gumbo-parser
It should be reasonably easy to call it from GNU APL.

If I were parsing HTML, I would have an exception list that contained the
few tags that don't have closing tags. I wouldn't expect a closing tag for
those. If I did get one, I'd ignore it.
There is a very small and fixed number of these exceptional tags. Custom
tags should have closing tags.

Hi Blake,
You're correct. Another problem in HTML is unquoted attribute values in
HTML tags.
I should have said "One can use ⎕XML for decoding HTML pages and the
like as long as
they obey the fundamental XML encoding rules".
I believe it would be possible to make ⎕XML tolerate some of these
All thoses request are based on the following piece of code i saw in 2004 (in
nars2000):
⎕cr '#BoxFMT'
Z←Z #BoxFMT R;RD;LD;D
LD←⍕(0≠⍴⍴R)/¯1↑⍴R
RD←⍕⍪¯1↓⍴R
RD←(+/RD=' ')⌽RD
D←¯2+⍴⍴Z
:if D>0
:while 2<⍴⍴Z
Z←,[¯3 ¯2] Z,[¯2]' '
:endwhile
Z←(-D)↓[0]Z
:endif
Z←(¯2↑1,⍴Z)⍴Z ⋄ Z←((⍴Z)⌈(¯1↑⍴RD),⍴LD)
Actually, when I said experiment I meant experiment with language design,
not using such features.
With KAP I decided to depart from standard APL on a few areas so that some
new interesting behaviour could be of implemented. A lot of of standard APL
works though.
Of course, if you are looking for
NARS2000-64 has already this kind of syntax while exactly having the core of
gnuapl/apl2 for maybe 10 years.
if you want to experiment download it (windows only and free)

I will ask again in 6 years.

Some of those "optional" end tags are not optional at all. It's not HTML
if it's there. For example:

Hi,
as far as I understand it, HTML has almost the same format as XML
(the main difference being optional end tags in
HTML which are mandatory in XML. I would assume that ⎕XML can do
the decoding of common web interfaces

This could be quite useful when collecting data from a web site. For
example, pull in a table of numbers from a Wikipedia page. Google Docs has
this feature already and it can be quite useful.

Sounds like another native function! :-)
Maybe after I finish my current project...

Just my two cents. I've never had a problem with what Chris is saying. In
fact, I think adding if/else as described earlier would make APL not APL.
If you want if/else as described earlier, just write your own apl'ish
language.
(I wrote my first APL 41 years ago.)

What's wrong with good old-fashioned computed-goto like:
1 testit y
2 v←hello first second byebye
3 →(y=⍳⍴v)/v
4 hello: 'hello'
5 →byebye
6 first: 'first'
7 →byebye
8 second: 'second'
9 byebye: 'byebye'
variations of which work fine as if/then/else, case statements, and
while/
In principle I agree with you. There are many occasions where an IF
statement in particular is useful, or even necessary. However, implementing
it in GNU APL would take careful consideration, and I know Jürgen wants to
make sure any new extensions doesn't contradict the principles of what APL
is.
