Hello,

the following example might not be the most minimal possible example,
but I hope that it is short enough. I'm using
    \setupheadertexts
        []
        [subject]
to print subject into header, but the headers are screwed up in some
very weird way. My real document behaves differently that this minimal
example, but even here one can notice that headers say:
- This is first heading
- This is fourth heading
- This is second heading
- This is fourth heading
instead of getting the second heading.

Does anyone have any idea what is going on?

Thank you,
   Mojca



\startbuffer[test1]
<html>
<body>
<h1>This is first heading</h1>
<p>some text</p>
<h1>This is second heading</h1>
<p>some text</p>
</body>
</html>
\stopbuffer

\startbuffer[test2]
<html>
<body>
<h1>This is third heading</h1>
<p>some text</p>
<h1>This is fourth heading</h1>
<p>some text</p>
</body>
</html>
\stopbuffer

\startxmlsetups all:html
    \xmlsetsetup{main}{h1}{*}
\stopxmlsetups

\startxmlsetups h1
    \subject{\ignorespaces\xmlflush{#1}}
\stopxmlsetups

\xmlregistersetup{all:html}

\setuphead
    [subject]
    [style=\bfa,
     page=odd]
\setupheadertexts
    []
    [subject]

\starttext
I have some text first
\xmlprocessbuffer{main}{test1}{}
\xmlprocessbuffer{main}{test2}{}
\stoptext

Add “expansion=yes” to \setuphead.

Thank you. Black magic worked.


Assuming that one would want to explain that option in reference
manual - what would be some short and clear explanation? When do I
need to use expansion?

it is also a side effects of using buffers

say that you do

\startsection[title=\xmlflush{#1}]

in fact what you then get is a reference to an xml node and that one is 
quite likely gone when you finish typesetting the buffer (that is, there 
is then a reference to a non existing node or maybe another one if you 
use the same buffer with some other xml) ; you can peek in the tuc file 
to see this in action

expansion will take the content but this also can have a side effect 
i.e. there can be nested elements

there are couple of options to deal with this (including piping back
snippets) and to some extend there is tracking of this

(mixing tex and xml in this way will always remain somewhat tricky)

eventually all this will be (and some already is) in the xml mkiv manual 
but ... it takes time ...
