XML processing from S3

s3-xml.jq

import module namespace s3 = "http://www.28msec.com/modules/s3";
import module namespace p = "http://zorba.io/modules/xml";

import schema namespace opt = "http://zorba.io/modules/xml-options";

(: In this example the XML files contains DTD declarations :)
let $parse-options := <opt:options>
    <opt:DTD-validate/>
</opt:options>
let $manifest := s3:read-text({
    "key": $id || "/manifest.xml",
    "bucket": "asups"
})
let $manifest := p:parse(string($manifest), $parse-options)
return $manifest
