I'm using BaseX as my XML based DB. I make a simple query like
xquery for $Book in
/Libraray/Literaturelist/Literature/Title return fn:data($Book)
I get all titles, just as a String that has got no line breaks.
Is there a way to add line-breaks with XQuery after each node found by the query to separate the data? This is not really dependant on my XML file because I do not add line-breaks hardcoded within the tags. ;)
it depends on how you retrieve the query results. The most elegant way is to use the iterator, as e.g. shown in:
http://basex.org/code/QueryExample
Apart from that, you could extend your XQuery by returning an additional newline:
xquery for $Book in /Libbraray/Literaturelist/Literature/Title
return (fn:data($Book), '
')
Note, however, that the additionally output space character cannot be suppressed.

PS: feel free to use the basex-talk mailing list to get feedback more quickly.
Another way to add a newline is to explicitly use the character reference for a newline:
xquery for $Book in /Libbraray/Literaturelist/Literature/Title
return (fn:data($Book), " ")
The XQuery 3.1 Serialization specification provides the new "adaptive" serialization mode, which outputs each XQuery result on a new line. Since BaseX 8, this mode is used as new default.
