Ah, I thought I had tried that, but it is working now.

Thanks /Andy

Hi Andy,

You can serialize the map by specifying the 'xquery' format as option:

map { "records": ["Huber", "Sepp", "Hauptstraße 13", "93547 Hintertupfing"], "names": ["Name", "First_Name", "Address", "City"] } => csv:serialize(map { 'format': 'xquery', 'header': true() })

The result:

​Name,First_Name,Address,City Huber,Sepp,Hauptstraße 13,93547 Hintertupfing ​ ​Cheers, Christian ​

The xqueryformat of CSV records as a sequence of arrays [1] is very useful when parsing but there seems to be no easy way to serialize from this format. Is this correct?

map { "records": ["Huber", "Sepp", "Hauptstraße 13", "93547 Hintertupfing"], "names": ["Name", "First_Name", "Address", "City"] } =>csv:serialize()

[SENR0001] Items of type map(xs:string, array(xs:string)) cannot be serialized.

... would be nice if it could. /Andy
