XML xmldoif struggle!

XML xmldoif struggle!

[Geert Verhaag]

Hi,

I've the following XML tag in my XML file:

<invoice number="194-002" client="RPMB-0012">
   <currency>EURO</currency>
.....

with invoice being the root tag!

Now I have a setup defined as below (only part!):

\startxmlsetups xml:invoice:invoice
   \xmlfirst{#1}{currency} \par
   \xmldoif{\xmlfirst{#1}{currency}}{contains(text(),'EURO')} {
      Euro set! \par
   }
.....

The \xmlfirst{#1}{currency} command prints EURO as expected.

But the xmldoif command doesn't cause the Euro set be printed?!

What's wrong here? The manual xml-mkiv.pdf doesn't give me any hint on 
how to make this work!

Regards,

Gerard

Hi Geert,

the syntax reads \xmldoif{#1}{lpath}{action}. So your conditional may read:

    \xmldoif{#1}{currency[first() and contains(text(),'EURO')]}
        {Euro set!}

In a complete sample (with dollar set first [it won’t show the result
unless you set EURO first]):

  \startbuffer[demo]
  <doc>
    <invoice number="194-002" client="RPMB-0012">
      <currency>DOLLAR</currency>
      <currency>EURO</currency>
    </invoice>
  </doc>
  \stopbuffer

  \startxmlsetups xml:initialize
     \xmlsetsetup{#1}{doc}{xml:*}
  \stopxmlsetups

  \xmlregistersetup{xml:initialize}

  \startxmlsetups xml:doc
    \xmlfirst{#1}{currency} \par
    \xmldoif{#1}{currency[first() and contains(text(),'EURO')]}
        {Euro set!}
  \stopxmlsetups

  \setuppapersize[A8]

  \starttext
     \xmlprocessbuffer{main}{demo}{}
  \stoptext

It is all in xml-mkiv.pdf
(http://www.pragma-ade.com/general/manuals/xml-mkiv.pdf#page=49). I have
just discovered it 😉.

Just in case it helps,

Pablo

Hoi Pablo,

Thanks for your prompt reply!

The output Euro set! is printed always, it doesn't matter whether I put 
EURO or DOLLAR first?!

Also I can't find any clue on the suggested page 49 of xml-mkiv.pdf 
manual, sorry!

By the way, in my document it still doesn't seem to work!

I'm afraid all this is far too complex for me! The documentation simply 
isn't meant for beginners like me, sorry!

Regards,
Gerard

Hi Geert,

my fault, the conditional should read:

    \xmldoif{#1}{currency[position()==1 and contains(text(),'EURO')]}
        {Euro set!}

I hope it works fine now.

Hi Pablo,

Yes, I got it working!

It is somewhat tricky.

Trying to understanding the concepts behind all this isn't easy for me, 
but I'm bashing on.

Thanks!

Gerard

I also find understanding XML processing rules to be complicated. I simply 
convert the XML to a lua table, and then use all the processing in lua 
using CLD (context lua documents).

Hi Aditya,

The ConTeXt team did a great job in writing the manual xml-mkiv.pdf, but 
I think it is not meant for a beginner.

Its contents is rather overwhelming when trying it for the first time.

For me, I don't use luatex a lot, so that adds to the difficulty of 
trying it out.

Regards,
Gerard
