G’Day,

Having a first go at converting TEI XML to ConTeXt.  

Steep learning curve, but easier (for me) than XSLT, and first results were amazing.  Using http://www.pragma-ade.com/general/manuals/xml-mkiv.pdf as a guide.

Currently stuck on converting an ISO format date (eg. 1908-01-10) into something more readable (eg. 10 January 1908) in the output.  I presume I should create a function (?luacode) that can take any ISO value and output the readable form.  The following works but seems to me inefficient.

Grateful for any pointers.

Mike

Here is my MWE:

\startbuffer[demo]
<TEI>
    <text>
        <body>
            <div type="letter">
                <opener>
                    <date when-iso="1908-01-10" type="divDate">10.I.08</date>
                </opener>
                <closer>
                <date when-iso="1908-03-19" type="secondDate">19 Mar '08</date>
                </closer>
            </div>
        </body>
    </text>
</TEI>
\stopbuffer

\startxmlsetups xml:initialize
\xmlsetsetup{#1}{date}{xml:date}
\stopxmlsetups
    
\xmlregistersetup{xml:initialize}

\startxmlsetups xml:date
\xmldoifelse {#1}{.[@type='divDate']} {
\def\docdate{\ctxlua{
local tyear = string.sub('\xmlatt{#1}{when-iso}',1,4)
local tmonth = string.sub('\xmlatt{#1}{when-iso}',6,7)
local tday = string.sub('\xmlatt{#1}{when-iso}',9,10)
context.date{d = tday, m = tmonth, y = tyear}
}}
    \docdate[day,month,year] = Document Date \par
    } {
\def\docdate{\ctxlua{
local tyear = string.sub('\xmlatt{#1}{when-iso}',1,4)
local tmonth = string.sub('\xmlatt{#1}{when-iso}',6,7)
local tday = string.sub('\xmlatt{#1}{when-iso}',9,10)
context.date{d = tday, m = tmonth, y = tyear}
}}    
    
    \docdate[day,month,year] = Event Date\par
}
