Best way to store text for later use

Best way to store text for later use

[Denis Maier]

Hi,

For typesetting XML I'm wondering how to best store text for later use:

I've tried using buffers, but this here doesn't work:

==================
\startxmlsetups xml:article-meta
     \setupdocument [
pub-year=\xmlfilter{#1}{/pub-date/year/command(xml:article-meta:pubdate:year)},
volume=\xmlfilter{#1}{/volume/command(xml:article-meta:volume)},
doi=\xmlfilter{#1}{/article-id[@pub-id-type='doi']/command(xml:article-meta:doi)},
elocation-id=\xmlfilter{#1}{/elocation-id/command(xml:article-meta:elocation-id)},
title=\xmlfilter{#1}{/title-group/article-title/command(xml:article-meta:title-group:article-title)},
         author={\AuthorList},
     ]
   \startbuffer[abstract]
       \xmlfilter{#1}{/abstract/command(xml:article-meta:abstract)}
   \stopbuffer
    \xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:article-meta:abstract
     \xmlflush{#1}
\stopxmlsetups
===================

This here works:

==================
\startxmlsetups xml:article-meta
     \setupdocument [
pub-year=\xmlfilter{#1}{/pub-date/year/command(xml:article-meta:pubdate:year)},
volume=\xmlfilter{#1}{/volume/command(xml:article-meta:volume)},
doi=\xmlfilter{#1}{/article-id[@pub-id-type='doi']/command(xml:article-meta:doi)},
elocation-id=\xmlfilter{#1}{/elocation-id/command(xml:article-meta:elocation-id)},
title=\xmlfilter{#1}{/title-group/article-title/command(xml:article-meta:title-group:article-title)},
         author={\AuthorList},
abstract=\xmlfilter{#1}{/abstract/command(xml:article-meta:abstract)},
     ]
    \xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:article-meta:abstract
     \xmlflush{#1}
\stopxmlsetups
===================

But has using a variable for the abstract any drawbacks? (The abstract 
might contain multiple paragraphs.)

Best,
Denis

A possibility is saving the data as text in a Lua-table. If you are not afraid to use some Lua, I can send my code for saving files and data for repeated use.

Why not just fetch it when needed. There is no gain in storing it and 
fetching from the xml tree is fast.

Most likely due to my limited understanding of how these things work. I 
thought storing the text and retrieving it later would be the easiest 
way to get rid of the constraints of linar processing of the XML file. 
The layout itself is determined by setups such as this one:

\startsetups abstract
     \startabstract
         \documentvariable{abstract}
     \stopabstract
\stopsetups

\setuphead [chapter][
     alternative=middle,
     page=yes,
     indentnext=no,
     style=\tfa\setupinterlinespace,
     after={\directsetup{placeauthors}\directsetup{abstract}},
     footer=chapterfooter,
     ]

How could I fetch the xml node from here so I don't need a variable, 
buffer or the like?

Denis

there is no linear processing, you just start someplace and recursively 
deal with the tree (which often looks like linear when you start at the 
root but basically you can access everything everywhere)

just pass the root element i.e. instead of #1 in

  \xmlfilter{#1}{/abstract/command(xml:article-meta:abstract)}

as #1 is just an abstraction for the current element; you pass the name 
you used when loading the tree (often \xmldocument works too)

there are plenty examples in the documentation and test suite and in 
some styles

Thanks. That is very helpful. And indeed, that makes things much easier!

Sorry, for answering only now. I've missed your response. That sounds 
interesting, and I'd be happy if you could send me your code.

Best,
