Hi Giuseppe, If you use fn:serialize, you can use the 'csv' parameter to assign CSV serialization options [1]. Hope this helps, Christian [1] http://docs.basex.org/wiki/Serialization Giuseppe Celano <celano@informatik.uni-leipzig.de> schrieb am Fr., 20. Juli 2018, 15:45:

Hi All,

I am not sure whether the serialize function is working properly (the first example works, the second does not, because instead of tabs I get commas, and there is no way to specify to add the header)

<csv> <record> <a>f</a> <b>f</b> <c>f</c> <d>f</d> <e>f</e> <f>f</f> </record> </csv> => csv:serialize(map{"header":"yes", "separator": " "})

return a b c d e f f f f f f f

<csv> <record> <a>f</a> <b>f</b> <c>f</c> <d>f</d> <e>f</e> <f>f</f> </record> </csv> => serialize(map{"method":"csv", "item-separator": " "})

f,f,f,f,f,f

Thanks! Giuseppe
