Hello Stefan,

Yes, it is.
Can I set options that influence this behavior or is this a bug?
Yes, you can. Set the CHOP option to false (see https://docs.basex.org/wiki/Options#CHOP for details) or start BaseX with the -w flag (which sets CHOP to false).
Hope that helps.
Cheers, Dirk
Though I think "CHOP" defaulting to true is a bug compared to the expected behaviour of XML.
And while it's very useful to have CHOP there for some kinds of data, for other kinds it's a severe hazard that it's the default. People have major freakouts when their documentation XML documents look like they've lost the white spaces around bold tags and will have nothing to do with BaseX thereafter.

True; this discussion is already going on for quite a while now. The default value of CHOP will be changed in a future version of BaseX.

Could we get _which_ future version? I recall this being said before 7.8 was released, too, and was feeling hopeful.
I understand that from a technical perspective this is a completely trivial thing -- set the flag! -- but from the perspective of having to argue for three months to be able to use BaseX at all at a client whose internal tester did a naive load of some narrative-style XML, observed the loss of white space around internal-to-the-mixed-content tags, and said "this application is banned", it's not trivial at all. Especially since it's not technically correct to the XML spec; one is forced to argue that something is a minor quirk of an otherwise excellent application *after* it's already given senior, stubborn, and non-technical content experts metaphorical heart attacks.

Hello Graydon,
As Christian already pointed out, we had this discussion on the mailing list quite frequently. See Christians answer from some time ago for some insight: https://mailman.uni-konstanz.de/pipermail/basex-talk/2013-April/004984.html
So although it is of course easily changed in our code, it does has some serious implications in terms of backward compatibility. So you might be able to convince your client by stating that we take backward compatibility seriously and will take some time and thought to change things that break applications :)
Cheers, Dirk

Hi Dirk --
I understand that you don't want to break backward compatibility, but a)it never gets easier, only harder, when you must do that, as more existing applications accumulate and b)the example given of the type of problem is seriously bad code. (I totally believe this kind of code exists in the wild; I can't muster much sympathy for an observation that "give me every text node in the document" is likely to go wrong, because my experience says it is _certain_ to go wrong, you never do that without qualifying which text nodes you mean.)
And, really, yeah, a commitment to backward compatibility is good; a commitment to preserving error is not, and the CHOP default behaviour is an error. Abstractions like backward compatibility don't even get into the discussion when the initial client response is "you changed our data and broke it". The client having that reaction wasn't very nuanced about it (and didn't immediately understand they were looking at a copy) but they weren't wrong. This really is a serious bug for mixed content.
So, please, could we get a release version commitment for when this bug will be fixed?
Thanks! Graydon

Hi Graydon, it is not so easy. For instance: The moment I turned off CHOP during import of my test data base, all of my unit tests involving assert-equals with a comparison of nodes failed because of extra of different whitespace. So this has indeed deep implications for running code. Stefan

Graydon,
It's a plain fact that we can't simply switch the default behavior of BaseX, because there are various applications out there that first need to be checked in depth before we can realize the switch. We simply need (..enough..) time to get aware of the consequences before we do simple things like inverting a boolean flag. I think there is no need to tell us what decision is right or wrong; we know by ourselves that there are enough reasons to change the default.
Please remember that BaseX is a completely free product. I'm glad to hear that you are using BaseX with customers, and that you believe it's an (otherwise) excellent choice. If you think that the current default is a serious show stopper that's worth to be fixed, you are invited to sponsor the efforts; this may be more helpful than complaining about the status quo.

Hi Graydon,
as already said, we are going to change the default and we are aware of the problem.
But I do think your statement that this is an error and we are "preserving errors" does not hold. As Liam Quin pointed out at https://mailman.uni-konstanz.de/pipermail/basex-talk/2013-April/004983.html it is in fact a quirky behavior of BaseX, but it does not contradict the spec.
Also, I'd like to remind everyone that it is fact quite easy to change the CHOP value, so this should also be possible at a client side.
We do understand the problems with the default value and take them seriously. However, there are implications with changing the default value and we have to consider them. A client would also certainly complain if we change default values all the time...
Cheers, Dirk

And, really, yeah, a commitment to backward compatibility is good; a commitment to preserving error is not, and the CHOP default behaviour is an error. Abstractions like backward compatibility don't even get into the discussion when the initial client response is "you changed our data and broke it". The client having that reaction wasn't very nuanced about it (and didn't immediately understand they were looking at a copy) but they weren't wrong. This really is a serious bug for mixed content.
So, please, could we get a release version commitment for when this bug will be fixed?
Thanks! Graydon

Hello Graydon,
As Christian already pointed out, we had this discussion on the mailing list quite frequently. See Christians answer from some time ago for some insight: https://mailman.uni-konstanz.de/pipermail/basex-talk/2013-April/004984.html
So although it is of course easily changed in our code, it does has some serious implications in terms of backward compatibility. So you might be able to convince your client by stating that we take backward compatibility seriously and will take some time and thought to change things that break applications :)
Cheers, Dirk

I understand that from a technical perspective this is a completely trivial thing -- set the flag! -- but from the perspective of having to argue for three months to be able to use BaseX at all at a client whose internal tester did a naive load of some narrative-style XML, observed the loss of white space around internal-to-the-mixed-content tags, and said "this application is banned", it's not trivial at all. Especially since it's not technically correct to the XML spec; one is forced to argue that something is a minor quirk of an otherwise excellent application *after* it's already given senior, stubborn, and non-technical content experts metaphorical heart attacks.

Yes, it is.
Can I set options that influence this behavior or is this a bug?
Yes, you can. Set the CHOP option to false (see https://docs.basex.org/wiki/Options#CHOP for details) or start BaseX with the -w flag (which sets CHOP to false).
Hope that helps.

Dear all (pasted from GitHub),
What about a mechanism like the output:cdata-section-elements option ? That way, one could set the list of elements not to be (recursivly) chopped.
For my usage (bibliographic data in intellectual propery domain), chopping by default is a good thing, because only a few document's elements contain textual mixed-content.
Hoping it helps,
Thank you Christian for the great job you do with your team.
