No, adding \relax to the xmlsetup did not solve the problem. Maybe I should try grouping or sprinkling around \relax in other places of my definitions? Just btw: I reported a similar problem this spring: http://archive.contextgarden.net/message/20080324.212853.4a4abc6c.en.html and realized later that again linebreaks are the culprit. From what I have understood, this is basically impossible: mkiv xml parsing uses the LPEG mechanism which doesn't see linebreaks as anything special. Nevertheless, I have these cases where introducing a linebreak makes elements from the xml tree disappear, removing it makes everything work. I'll keep an eye on it (and am aware that there may not be an immediate solution).

Hi all, Hans,
this is a terribly inaccurate bug report, and I apologize for its
form, but it's something you and other people might want to look at.
Or maybe I should change my files, I don't know. Here comes:
SUMMARY
The new mkiv xml parser sometimes eats parts of my xml files when
they are typeset. It appears to skip parts of text between two tags.
DESCRIPTION
I have no minimal example, just a description: for my lectures, I have
defined a counter to tell me when I want to show the next slide:
\definelabel[SlideNumber][headstyle=normal,way=bytext]
\define\sln{\color[red]{ [\nextSlideNumber]}}
For my xml files, I have wrapped this into a xml command:
\startxmlsetups xml:sln
\sln
\stopxmlsetups
This works wonderfully in most cases. To make my source file more
readable, I usually code
foo
sln/
bar
In this case, the xml parser SOMETIMES (not reproducibly,
unfortunately) skips the bar part up to the next paragraph p tag.
When I take away the line break and write
foo sln/ bar
the bar part appears normally.
ANECDOTE
I write my lectures in xml so I can put them on a website for my
students, and I deliver them from typeset notes. This happened to me
last Tuesday. I had typeset and printed my notes, and then while
lecturing realized that an entire paragraph was missing. I could ad-
lib it, but this is not something you want to happen at an important
job-talk...
I don't if this will help you but you can try the following three changes.
1. Change the defintion of \sln
\define\sln{\startcolor[red][\nextSlideNumber]\stopcolor}
2. Put a \relax after the xml setup for \sln
\startxmlsetups xml:sln
\sln\relax
\stopxmlsetups
3. define \SlideNumber as TeX counter
\newcount\SlideNumber
\def\resetSlideNumber
{\global\SlideNumber\zerocount\relax}
\def\incrementSlideNumber
{\global\advance\SlideNumber\plusone\relax}
\def\currentSlideNumber
{\number\SlideNumber\relax}
\def\nextSlideNumber
{\incrementSlideNumber
\currentSlideNumber}
(4. Switch the system or TeX installation, helped on my former
Windows installation with font problems)

Hi Wolfgang,
thanks for your suggestions! I tried solutions 1-3, but I still get
the same result; the paragraph is skipped (hey, what about #3: are you
leading me into temptation to use low-level code?!). #4: I have tried
both the minimals and a fully updated TeXLive on OS X; I will tomorrow
check if the same thing happens on my linux installation.
Unfortunately, the file is pretty long and contains some additional
modules and fonts, or I'd send it to you to see if it compiles OK on
your installation (though: could I imagine switching to Windows? No, I
couldn't...)
All best, and thanks a lot
Thomas

There is nothing wrong with low level code if you know what you do
*and* counters are faster (but you won't notice the difference here :)
#4: I have tried
both the minimals and a fully updated TeXLive on OS X; I will tomorrow
check if the same thing happens on my linux installation.

You could send me your files. I switched from windows to Mac
and most of my problems disappeared.
