Dear list,
I have the following sample:
\startbuffer[demo]
<html>
<body>
<div id="First">
<p>This is
<span class="special">One of the best</span> a paragraph.</p>
<p>This is another paragraph.</p>
<p>This is another
<span class="special">Two of the best</span> paragraph.</p>
<p>This is another
<span class="special">Three</span> paragraph.</p>
<p>This is another
<span class="special">Four of five</span> paragraph.</p>
</div>
</body>
</html>
\stopbuffer
\startxmlsetups xml:initialize
\xmlsetsetup{#1}{html}{xml:gen}
\stopxmlsetups
\xmlregistersetup{xml:initialize}
\startxmlsetups xml:gen
\xmlfilter{#1}{/**/div/command(xml:special)}
\stopxmlsetups
\startxmlsetups xml:special
%~ \startitem
\cldcontext{string.gsub(lxml.flush([[#1]]),
" of the ", "")}\stopitem
\stopxmlsetups
\starttext
\xmlprocessbuffer{main}{demo}{}
\stoptext
Is there any way to remove " of " and " of the " in the filtered content
(xml:special)?
Sorry, Lua code is crap for sure.
Many thanks for your help,
Pablo

There is pretty much always ‘a way’, but I do not know of a ’nice’ way.
Your problem is that lxml.flush() and friends do not return a value,
they just do a direct context(‘xxxx’) call behind the scenes with no
return string for you to modify.
Also, the special (catcode, space handling) rules for setups and \cldcontext
do not help you.
That does not mean it can’t be done. As I don’t know a of a nice way,
here is a low-level ‘ugly' way:
\startluacode
function filter(a)
local div = lxml.getid(a)
process(div)
lxml.flush(div)
end
function process(div)
for c=1,#div.dt do
if type(div.dt[c]) == 'string' then
div.dt[c] = string.gsub(div.dt[c], " of the ", "")
else
process(div.dt[c])
end
end
end
\stopluacode
\startxmlsetups xml:special
\ctxlua{filter([[#1]])}
\stopxmlsetups
process() is recursive because your xml:special gets the whole <div>. Not sure if you intended it that way.
And if it can be done nicer, I am sure someone will correct me :)
Best wishes,
Taco

You’re right, my xml:special wasn’t intended to get the whole <div>. I
was tinkering with a previous sample. And I removed an \xmlfilter. Since
I got no output, I didn’t see what I was missing.
Many thanks for your help,
Pablo

Or make a finalizer as Taco posted.

Many thanks for your reply, Hans.
I now see that \xmlraw is the way to go.
I have two questions in word replacement and Lua (maybe there is some
lpeg magic that could be used).
This time, I have to remove two words, such as in:
string.gsub([[\xmlraw{#1}{.}]]," del ", " "):gsub(" de la ", " ")}
But they could be more (and replacements might be added to that list).
Is there a more elegant way than appending :gsub()?
Is there also a proper way for word scanning?
A "word" can be "Word ", " word " " word." " word?" (and so on). I would
like to avoid having to code all combinations (of course, if this were
already available).
Many thanks for your help,
Pablo

old stuff present for a long time ... probaly documented somewhere ...
if not than you have to wikify it ...
\starttext
\replaceword[whatever][this][that]
\replaceword[whatever][that][this]
\startlines
it is this or that
{\setreplacements[whatever]it is this or that}
it is this or that
\stoplines
\stoptext

Many thanks for your reply, Hans.
It is already wikified
(https://wiki.contextgarden.net/Ligatures#Replacements).
I wonder whether \replaceword could be extended to replace multiple
words and also to remove them.
\starttext
\replaceword[whatever][this or][no]
\replaceword[whatever][that][]
\startlines
it is this or that
{\setreplacements[whatever]it is this or that}
{\setreplacements[whatever]it is this or that}
it is this or that
\stoplines
\stoptext
Many thanks for your help,
Pablo
