Hello,
I was trying to figure out how to process simple HTML files with the
new code, but I fail to understand the details. Here's a simple file I
would like to process:
<html>
<head>
<title>My first HTML2ConTeXt</title>
</head>
<body>
<h1>Main Title</h1>
<p>Some text ...</p>
<h2>Subtitle</h2>
<p>Some text again ...</p>
<h1>Second title</h1>
<p>... and not much more text here either ...</p>
</body>
</html>
And the failed tries here:
% engine=luatex
\setupcolors[state=start]
\setuphead[subject][style=bfa,color=blue]
\setuphead[subsubject][style=tfa,color=blue]
\starttext
\xmlload{main}{test.html}{}
\xmlgrab{main}{h1}{h1}
\xmlgrab{main}{h2}{h2}
\startxmlsetups h1
\subject{H1: #1}
\stopxmlsetups
\startxmlsetups h2
\subsubject{H2: #1}
\stopxmlsetups
How to grab only the title out of here?
\xmlfilter{main}{html/head/title}
\xmlflush{main}
\stoptext
Any hints most wellcome.
Thank a lot,
Mojca

keep in mind that this is still somewhat experimental
% best define mappings before loading the file
\startxmlsetups all:html
\xmlsetsetup{main}{head|h1|h2}{*}
\stopxmlsetups
\xmlregistersetup{all:html}
% register this so that it's done for each load
\startxmlsetups h1
\subject{\xmlflush{#1}}
\stopxmlsetups
\startxmlsetups h2
\subsubject{\xmlflush{#1}}
\stopxmlsetups
\startxmlsetups head
\startstandardmakeup
THIS IS ABOUT: \xmlfilter{main}{/head/title/text()}
\stopstandardmakeup
\stopxmlsetups
% that's it
\setupcolors[state=start]
\setuphead[subject][style=\bfd,color=blue]
\setuphead[subsubject][style=\bfc,color=blue]
\starttext
\xmlprocess{main}{test.html}{}
\stoptext

Sure :)
That's why I'm sending files for testing :) :) :)

Great! This works perfect and seems much easier to write than the old
code, though I still have no idea how to implement some parts of it:
- where to plug in the entities such as , ≤, ...
- how to catch classes: how to differentiate between <h1>title</h1>
and <h1 class="...">title</h1>
- and some more - there are some simple examples in the attachment
(too long to copy-paste)
Thanks again,
Mojca

or just load the regular entity handlers (mkii still works and can be
used mixed)

Thanks. I saw it, but had no idea how to use it. I need to test more
extensively ... :)

I have tried exactly that before, but this example fails to work for
me, or I don't know how to apply it:
% test.html
<html>
<body>
<h1>Title 1</h1>
<h1 class="different">Title 2</h1>
</body>
</html>
% test.tex
\startxmlsetups all:html
\xmlsetsetup{main}{h1}{*}
\stopxmlsetups
\xmlregistersetup{all:html}
\startxmlsetups h1
This title belongs to class (\xmlatt{#1}{class}): \xmlflush{#1}.\par
\stopxmlsetups
\starttext
\xmlprocess{main}{test.html}{}
\stoptext
Class always comes out empty.
Thanks a lot,
Mojca

Hello Hans,
Thanks a lot for fixing the issue with non-working \xmlatt.
Now, I'm still slightly lost regarding two issues:
- How to remove unneeded space? With \ignorespaces?
- How to use the new verbatim code? I have tried to use
\xmlsetfunction{main}{pre}{lxml.verbatim}
but it didn't really work.
% test.tex:
\startxmlsetups all:html
\xmlsetsetup{main}{h1|pre}{*}
\stopxmlsetups
\xmlregistersetup{all:html}
% is this the proper way?
\startxmlsetups h1
\subject{\ignorespaces\xmlflush{#1}}
\stopxmlsetups
\startxmlsetups pre
{\bgroup\tt\obeylines\xmlflush{#1}\egroup}
\stopxmlsetups
\starttext
\xmlprocess{main}{test.html}{}
\stoptext
% test.html
<?xml version="1.0" encoding="utf-8"?>
<html><body>
<h1>
How to get rid of this spacing in some elegant way?
</h1>
<p>Title followed by a paragraph ...</p>
<pre>
and
some source
c@de
</pre>
</body></html>
Also, this fails because of the empty line:
<h1>
How to get rid of this spacing in some
elegant way?
</h1>
Thanks a lot,
Mojca

- i'll make a table mapper (need it anyway), cals tables are already
provided
- idem for preformatted and verbatim
- your code:
d[k] = dk:gsub(" ",' ')
dk = d[k]
d[k] = dk:gsub("≤", '\\mathematics{\\le}')
local dk = d[k]
dk = dk:gsub(" ",' ')
dk = dk:gsub("≤", '\\mathematics{\\le}')
d[k] = dk
or ....
mojcasentities = {
nbsp = " ",
le = "'\\mathematics{\\le}'
}
local d[k]= d[k]:gsub("&(.-);",mojcasentities)
(there probably already is code for that)

Thanks a lot!

Yes, I saw it, but didn't try to understand what the &(.-) serves for.
In any case, that was the wrong place to replace le with something.
Thanks again,

(Caveat: I do not really know lua regex, and have not tried out the
code)
Assuming lua follows standard regex syntax, this means
& # The letter &
( # start a group
. # any character
- # As few as needed
) # end group
; # the letter ;
so this will match all entities.
If it helps, the equivalent vim regex will be
\&\(.\{-}\);
I guess that $1 (the first group, that is everything that matches .-)
will be compared with mojcaentities table and replaced accordingly.
This looks like a really nice feature of lua. In Ruby and Vim, I often
find myself writing a bunch of similar regex, and always wished there
was something like what lua does.

they are not regexp but expressions -)

just &(.-); with () being the capture

indeed

the nice thing about many lua feature is that less code (lua c code)
behaves more powerful
