node-set array([node-set nodes])

wraps the nodes of the node set nodes in a <json array="">…</json> structure, so that they can be used as an array in a JSON Template.

if the nodes contain an attribute (e.g. a="b"), it will be converted to an element <value name="a">b</value>), so that key and value are easily accessible in the template.

Example

JSON:

{"users": [ {"name": "Alice"},{"name": "Bob"}]}

Template-Action:

<template>
   { "names": {{ array(users//name) }} }
</template>

Output:

{ "names": ["Alice","Bob"] }
