xml input

[Meer, Hans van der]

[-- Attachment #1.1: Type: text/plain, Size: 624 bytes --]

I would like to process several input sources as one xml tree. Like this:

<?xml version="1.0" encoding="UTF-8"?>
<takenotes>
<include buffer="notes-example"/>
<include file="notes-example.xml"/>
</takenotes>

with the sources having the structure
<notes>
<note>...</note>
...
</notes>

and the code for <takenotes> containing:
read from all sources given on <include>-notes
afterwards process all content at once

Thus the content of the various source should be read into one tree to be processed, but I cannot get this done.
How to amalgam this separate sources into one?

Just a thought.

\xmlprocessbuffer and \xmlprocessfile{id}... register the tree they read under id. Is there a way to merge several id's to one tree?

no, but you can of course access trees mixed (as long as #1 reflects id)

How to amalgam this separate sources into one?

a clue: \xmlinclude

By the way: hoe laad ik de inhoud van een buffer net als van een file, is er een buffer equivalent van \xmlinclude?

Hans, het spijt me zeer, maar ik begrijp er geen hout meer van want er volgt een crash met een lua-error.
Ik lees voor \xmlinclude dat \xmlinclude{NODE}{LPATH}{ATTRIBUTE} de file in het attribuut laadt.

Ik heb wat in de code rondgeneusd.
Uit  lxml            > tex > including file 'notes-example.xml'
in de log blijkt dat in function lxml.include(id,pattern,attribute,options)
moet zijn uitgevoerd

            if trace_loading then
                report_lxml("including file %a",filename)
            end
            noffiles, nofconverted = noffiles + 1, nofconverted + 1
            return resolvers.loadtexfile(filename) or ""

Met resolvers tracking komt hier nog tussen:
lxml            > tex > including file 'notes-example.xml'
resolvers       > methods > resolving, method 'finders', how 'uri', handler 'file', argument 'notes-example.xml'
resolvers       > resolving > remembering file 'notes-example.xml' using hash 'xml::notes-example.xml'
resolvers       > files > file finder: 'notes-example.xml' found
resolvers       > methods > resolving, method 'loaders', how 'uri', handler 'file', argument 'notes-example.xml'
resolvers       > files > file loader: 'notes-example.xml' loaded
het lijkt erop dat de gezochte file wel geladen is en dat pas daarna ConTeXt het opgeeft met de error.

De log geeft me hier:

HVDM-NOTE-DEBUG > enter notes:include
HVDM-NOTE-DEBUG > ..looking for file notes-example.xml
lxml            > tex > including file 'notes-example.xml'

lua error       > lua error on line 14 in file /Users/hansm/Documents/TeX/texmf/publications/takenotes/take notes.tex:

...-35/tex/texmf-context/tex/context/base/mkiv/lxml-aux.lua:428: attempt to index field 'settings' (a nil value)
stack traceback:
...-35/tex/texmf-context/tex/context/base/mkiv/lxml-aux.lua:428: in function 'include'
...-35/tex/texmf-context/tex/context/base/mkiv/lxml-tex.lua:579: in function <...-35/tex/texmf-context/tex/context/base/mkiv/lxml-tex.lua:567>
(...tail calls...)


De navolgende code is toch niet fout?

De main input is
<?xml version="1.0" encoding="UTF-8"?>
<takenotes>
  <!-- <include buffer="notes-example"/> -->
<include file="notes-example.xml"/>
</takenotes>

De file notes-example.xml bevat slechts
<note> subnodes </note> etc
omsluiten met <root>...</root> doet niets anders.

Ik doe het volgende (met loading tracker enabled
\startxmlsetups notes:takenotes
  % Include files and buffers.
  \xmlfilter{#1}{/include/command(notes:include)}
\stopxmlsetups

\startxmlsetups notes:include
  % Include from file.
 \doifnot{\xmlatt{#1}{file}}{\empty}
    {\writestatus{HVDM-NOTE-DEBUG}{..looking for file \xmlatt{#1}{file}}
     \xmlinclude{#1}{}{file}}
\stopxmlsetups

Zelfde crash in de volgende gevallen
\xmlinclude{#1}{}{file}
\xmlinclude{#1}{.}{file}
\xmlinclude{#1}{../include}{file}

Re: xml input

[Pablo Rodriguez]

Hans,

excuse my top-posting.

I was really interested in this thread. But Dutch isn’t something in
between English and German (two languages I used to know).

My apologies for the comment, if the message was intended as private.

I’m eager to learn XML in ConTeXt, since the possibilities are less than
with standard (or the other) ConTeXt.


Pablo

My fault, wholly my fault! 
Just didn't look precise enough in replying. 
Thought to answer Hans Hagen in private but was a little offguard.
No offense taken.

Re: xml input

[Meer, Hans van der]

[-- Attachment #1.1: Type: text/plain, Size: 3885 bytes --]

A week ago I posted here by accident part of a private conversation (in Dutch) with Hans Hagen. I already apologized for this.

On 15 Apr 2016, at 00:47, Mica Semrick <mica@silentumbrella.com<mailto:mica@silentumbrella.com>> wrote:

I'm interested in this thread too... But I'm american, so English only. I appreciate your understanding!


From reactions I understood that other people are interested in this subject of \xmlinclude too, but at that moment I could not produce a coherent story.
After having produced some minimal (1) working, (2)  not working and (3) crashing examples, I dare hope that my contribution of these will be of some use. And perhaps they will spawn better suggestions and better understanding of what happens, because I must confess I am somewhat unsure with functional language behaviour, being raised with Assembler, Algol, Pascal, Fortran, and so on ;-)

Find below my examples. One can call each of them by commenting out the \starthiding.
The last one can be executed by removing the %%%%'s at the front of the offending statement.
Again, I hope this post will be of some use.

For those still interested in the inclusion of nodes into the root of the xml-tree.
With the help of a hint by Hans Hagen, the following is the best I am able to produce.
The code below includes the contents of the file twice as can be seen in the pdf.

\startbuffer[test]
<?xml version="1.0" encoding="UTF-8"?>
<takenotes>
<include file="minimal-example.xml"/>
<include file="minimal-example.xml"/>
</takenotes>
\stopbuffer

\startxmlsetups notes:setups
\xmlinclude{#1}{include}{file}
\xmlsetsetup{#1}{takenotes}{notes:*}
\stopxmlsetups
\xmlregisterdocumentsetup{demo}{notes:setups}

\startxmlsetups notes:takenotes
\xmlshow{\xmldocument}
\stopxmlsetups

\starttext
\xmlprocessbuffer{demo}{test}{}
\stoptext
