In XML values in text   nodes  If we write this  lt numbers gt 1 2 3 lt  numbers gt   in element  quot numbers quot  will be one text   node with value  quot 1 2 3 quot   Native way to get many text   nodes in element is insert nodes of other types in text  Other available types is element or comment   node  Split with element node   lt numbers gt 3 lt    gt 2 lt    gt 1 lt  numbers gt   Split with comment   node   lt numbers gt 3 lt  ---- gt 2 lt  ---- gt 1 lt  numbers gt   We can select this values by this XPath   numbers text    Select value by index   numbers text   3   Will return text   node with value  quot 1 quot

As its name is  numbers  it is clear it is a list of number    So an array of number    no need of the attribute type    Although I like the principle of specifying the type of field in a type attribute

The second way isn t valid XML  did you mean  lt numbers gt  3 2 1  lt  numbers gt    If so  then the first one is preferred because all you need to get the array elements is some XML manipulation  On the second one you first need to get the value of the  lt numbers gt  element via XML manipulation  then somehow parse the  3 2 1  text using something else   Or if you really want some compact format  you can consider using JSON  which  natively  supports arrays   But that depends on your application requirements
