Hi Stefania,

Sorry for the delay.

If I run you example, I **think** it behaves as intended, all <a/>-Elements but the one marked with xml:space are chopped.

This is what it looks like here: 
https://asciinema.org/a/4v1FtkeE1QsEByHe1S2BAZP9W
michael@mbp:~/tmp/ml|⇒  cat example.xq
db:create('test',
"<doc>
  <a>  stefy  </a>
  <a xml:space='preserve'>  stefy  </a>
  <b>  stefy  </b>
</doc>",
"doc.xml"
)
michael@mbp:~/tmp/ml|⇒  basex example.xq
michael@mbp:~/tmp/ml|⇒  basex "db:open('test')"
<doc>
  <a>stefy</a>
  <a xml:space="preserve">  stefy  </a>
  <b>stefy</b>
</doc>%

…if I add CHOP=false, the whitespace will be kept on all elements:

I am sure we will eventually be able to solve this mystery :-)

thanks  Michael

I run your suggestion and it seems to affect all the elements on my BaseX.
I also verified that the 'chop' property was still true after the execution of the xquery
(> open test
Database 'test' was opened in 7.29 ms.
> get chop
CHOP: true)

db:create('test',
"<doc>
  <a>  stefy  </a>
  <a xml:space='preserve'>  stefy  </a>
  <b>  stefy  </b>
</doc>",
"doc.xml"
)
========>>>>>
<doc> <a>  stefy </a> <a xml:space="preserve">  stefy  </a>
  <b>  stefy </b>
</doc>



db:replace("test", "doc1.xml",
"<doc>
  <a>  stefy  </a>
  <b>  stefy  </b>
</doc>")
========>>>>>
<doc> <a>  stefy </a>
  <b>  stefy </b>
</doc>

Am i missing something?
thanks
Stefania

Hi & thanks Gerrit,
Hi Stefania,

You may even decide to chop-or-not on a per-element basis:
db:create('test',
"<doc>
  <a>  stefy  </a>
  <a xml:space='preserve'>  stefy  </a>
</doc>",
"doc.xml"
)

Will preserve whitespace in the second <a />-Element while chopping in the first one.

Luckily you can switch it off.
