Re: [basex-talk] bug (?) in fn:serialize

... just checked. When the node is from a document instance than
serialize does keep whitespace (with or without xml:space).

And this clears up a confusion I had about what an element constructor
is and what a direct element constructor is.

For fun I tried serialize(element e { '   ' }) which happily returns 

Somebody wants to write that book on XML/XSLT/XQuery and whitespace?

Thanks, Alexander and everybody for your remarks and observations.
As it happens, in the meantime I've found the reason: it is the boundary-space 
policy, which can either be "preserve" or "strip" and which a boundary-space 
declaration of the prolog can explicitly choose (overriding the 
implementation-defined default) [1]. Therefore:
declare boundary-space preserve;
serialize( )

yiels
 
as it should, hurray! One of so many opportunities to note the high quality of 
BaseX which honours such a rather obscure declaration.
The XQuery spec also states explicitly that xml:space has no effect in this 
context (from [2]):"Element constructors treat attributes namedxml:space as 
ordinary attributes. Anxml:space attribute does not affect the handling 
ofwhitespace by an element constructor."
So BaseX is doing just the right thing.

Everything is fine!
Cheers,Hans-Jürgen
PS: For the interest, here the definition of boundary-whitespace 
([2]):[Definition: Boundarywhitespace is a sequence of consecutive whitespace 
characterswithin the content of a direct element constructor, that isdelimited 
at each end either by the start or end of the content, orby a 
DirectConstructor, or by anEnclosedExpr. For thispurpose, characters generated 
by character references such as or by CDataSections are not consideredto 
be whitespace characters.]

Maybe your data is stored/processed with whitespaces stripped off?

Re: [basex-talk] bug (?) in fn:serialize

2016-09-09 Thread Wiemer, Sebastian 
It seems to be a problem with elements containing only whitespace characters:

serialize(
  
Demonstrating the CHOP flag
  
  To be  
   , or not to be 
   dasdf , that is the question.
)

 Tags work as expected, but  Tags will be stripped to the empty element 
.
Maybe this has to do with the handling of empty elements?

Hmm first I thought not a bug and that the fix would be to do

serialize(   )

but to my surprise this results in



(with CHOP = false)

That doesn't seem right.

Whereas

serialize()

does what you expect.

Dear BaseX team,
is this a bug?
