Here an example as minimal as I could construct.
The spaces in the output are produced by the spaces between the tags
(\xmlstrip doesn’t seem to work)
and you have to use a combination of \removeunwantedspaces and \ignorespaces
to remove them.
To center your table this isn’t necessary when you replace \midaligned with a
framedtext
environment in combination with “location=middle” or use a float command like
\placefigure.
\startxmlsetups xmlcommon
\xmlsetsetup{\xmldocument}{table|tr|td}{xmlcommon:*}
\stopxmlsetups
\xmlregistersetup{xmlcommon}
\startxmlsetups xmlcommon:table
% \removeunwantedspaces
\startembeddedxtable
\xmlflush{#1}
\stopembeddedxtable
% \ignorespaces
\stopxmlsetups
\startxmlsetups xmlcommon:tr
% \removeunwantedspaces

\stopxmlsetups
\startxmlsetups xmlcommon:td
% \removeunwantedspaces
\startxcell
\xmlflush{#1}
\stopxcell
% \ignorespaces
\stopxmlsetups
Input from file or from buffer doesn't make a difference.
I inserted the \removeunwantedspaces and \ignorespaces, as you suggested. The
xmlstrip macros do not make any difference, either active or commented out.
Then there still remains extra space at the end. See below.

There is something I do not understand and I hope you can explain this. The
table is typeset by the \xmlflush{#1} in the table macro:
\startxmlsetups xmlcommon:table
Z\bgroup
\setupxtable[% Setup defaults
leftmargindistance=0pt,rightmargindistance=0pt,
offset=2pt,height=fit,width=fit,
align={center,lohi},columndistance=0pt]

\startlocationbox{#1}
\removeunwantedspaces
\startembeddedxtable X\xmlflush{#1}Y\stopembeddedxtable
\ignorespaces
\stoplocationbox
\egroup
\stopxmlsetups
The X and Y have been placed around the \xmlflush to see what happens. Why
do I see them 3 times? It looks as if the embeddedxtable-line is called 3
times (or maybe 4 times once for each row with the last call vanishing).
However, the table macro itself is called only once, the Z at the beginning
proves that. I cannot explain this.
Another observation: inserting a newline after the ?xml-tag also does insert
a space just before the Z.

This is normal and needed for the calculation of the cell widths and heights.
This mechanism is called trial typesetting and used by a few mechanism (e.g.
float captions) to get the dimensions of the content.

I think I can reduce the number of places where spaces have to be suppressed.
With just 2 \removeunwantedspaces and 1 \ignorespaces I get rid of most of

Only 1 space remains inside the framed: in the vertical dimension below the

It’s impossible to tell what’s wrong with our code snippets, you have to create
working minimal examples.
The following example shows where you have to take care of extra space and you
don’t need them when you put the whole table in a \vbox (you can test by
commenting all \ignorespaces and \removeunwantedspaces commands and replacing
\ruledhbox with \ruledvbox).

With the construct

I used to get a neatly centered content. But now the material is shifted to the
right, even sticking out of the page.
Has something changed in the embeddedxtable alignment handling since the end of
2013?
(The embeddedxtable macro was needed because the typeset material exists inside
\startbuffer..\stopbuffer.)

Wolfgang
Here an example as minimal as I could construct.
Hans van der Meer
The following example outputs show what happens with and without the \unskip's
in the code.
[cid:E7DC008D-E8CB-4F0A-BC45-9E8E4969C8DB]
[cid:8A14737A-52AE-4B90-A03B-FA36FFF321E0]
Also I am adding two other examples made by the same code, one in 2012 and one
just now. Note the extensions to the right of each row. They are absent in the
older version.
[cid:1110D708-ADD3-46B8-A49B-143200704DA7][cid:539F8473-CC40-4CDB-AFC6-48AF306DD3F5]

Here an example as minimal as I could construct.
The spaces in the output are produced by the spaces between the tags (\xmlstrip
doesn’t seem to work)
and you have to use a combination of \removeunwantedspaces and \ignorespaces to
remove them.
To center your table this isn’t necessary when you replace \midaligned with a
framedtext
environment in combination with “location=middle” or use a float command like
\placefigure.
