[basex-talk] Item Separator

Hello

I am serialising the following expressions on oxygen/saxonEE12.3 as text (item-separator=“”) and wonder why the differente outputs

let $xml:=<xml><element>text1</element><element>text2</element></xml> return $xml/element/text()

gives text1text2

And

let $xml:=<xml><element>text1</element><element>text2</element></xml> return $xml/element/string()

text1 text2

When I set the item-separator =“, “ then I get

text1, text2

Or

text1, , text2

Any explanations???

Thanks, Leo
