Hi Kari,
I'm not sure why the map:* API works that way, but you have to be explicit in
getting the values from the elements in question. Specifically, you can use
fn:string() to get the element contents as a string, you can use fn:data() to
defer to any applicable schema types, or you can use the xs:* type constructors
(xs:integer(), xs:decimal(), etc.).
You can apply the types in the map:
let $map := map:new((
map:entry("EventTitle", $theEvent/fn:string()),
map:entry("EventStartDate", $theStartDate/fn:string())
))
Or earlier, in your variable bindings:
let $theEvent:= $doc/EventTitle/fn:string()
let $theStartDate:=$doc/EventStartDate/fn:string()
Thanks.

It’s ML 7
How would I get back the values rather than the node paths?
In other words, this:
let $outputSimpleJSON:=("{"events":[",
fn:string-join(
for $doc in $search-this-partner/event (: there are 3 records in this set :)
let $theEvent:= $doc/EventTitle
let $theStartDate:=$doc/EventStartDate
let $map := map:new((
map:entry("EventTitle", $theEvent),
map:entry("EventStartDate", $theStartDate)
))
return xdmp:quote(xdmp:to-json($map)),","),
"]}")
Returns a valid JSON object for the 3 records returned, but it doesn’t have
the values of the data.
Example: >>
{"events":[
{"EventStartDate":"fn:doc(\"\/data-sources\/events\/Akira_7877013.xml\")\/event\/EventStartDate",
"EventTitle":"fn:doc(\"\/data-sources\/events\/Akira_7877013.xml\")\/event\/EventTitle"},{"EventStartDate":"fn:doc(\"\/data-sources\/events\/TheDayTheEarthStoodStillMarch08,2017.xml\")\/event\/EventStartDate",
"EventTitle":"fn:doc(\"\/data-sources\/events\/TheDayTheEarthStoodStillMarch08,2017.xml\")\/event\/EventTitle"},{"EventStartDate":"fn:doc(\"\/data-sources\/events\/Solaris_956351.xml\")\/event\/EventStartDate",
"EventTitle":"fn:doc(\"\/data-sources\/events\/Solaris_956351.xml\")\/event\/EventTitle"}
]}
I need the values, like this – any way to do it?
{"events":[
{"EventStartDate":"2018-03-08", "EventTitle":"Akira"},
{"EventStartDate":"2017-03-08", "EventTitle":"The Day The Earth Stood Still"},
{"EventStartDate":"2017-09-30", "EventTitle":"Solaris"}
]}

Hi,
Your code is working fine and getting expected result . Could you please tell
me what version of ML u r using.

Just returning to this, I wanted to try constructing the map, but instead of
getting back the values, I get back the document URI and path to the node.
Not what I expected. What am I doing wrong?
let $outputSimpleJSON:=
for $doc in $search-this-partner/event (: there are 3 records in this set :)
let $theEvent:= $doc//EventTitle
let $theStartDate:=$doc/EventStartDate
let $map := map:new((
map:entry("EventTitle", $theEvent),
map:entry("EventStartDate", $theStartDate)
))
return xdmp:to-json($map)
>>
{"EventStartDate":"fn:doc(\"\/data-sources\/events\/Akira_7877013.xml\")\/event\/EventStartDate",
"EventTitle":"fn:doc(\"\/data-sources\/events\/Akira_7877013.xml\")\/event\/EventTitle"}

Hi Kari,
You can use the "custom" strategy with json:config():
http://docs.marklogic.com/json:config. There are lots of options that can be
specified to control the transformation(for instance, "ignore-attribute-names").
Alternately, you can manipulate the resulting JSON object, or even code your
own transformation. One of the simplest ways to implement your own
transformation is to construct nested maps from the data you want, and then
convert the map to json:
let $map := map:new((
map:entry("key", "value"),
map:entry("anotherKey", "a different value")
))
return xdmp:to-json($map)
Thanks.

Subject: [MarkLogic Dev General] Custom JSON objects
I had a question from someone on my team if it’s possible to return a more
simplified version JSON without child and attributes.
For example, compare Events JSON object:
http://data.smartlitigator.com/EventTools/GetEventsTable?display=New+York+Law+Journal|returnType=JSON
To this:
http://data.smartlitigator.com/QuestV2/Search/?query=law&publication=§ion=&orgType=&elementType=&articleType=&practiceArea=&virtualPracticeArea=&subject=&industry=&source=lawcom&almStaff=&lawTopic=&fromDateTime=&toDateTime=&fromDate=1985-01-01&toDate=2015-11-07&start=1&end=10&sort=rank&direction=descending&returnType=falcon_json&callback=
Events, simply contructed snippet:
let $outputJSON:=("{"events":[",
let $config := json:config("full"),
$cx := map:put( $config, "whitespace", "ignore" )
return fn:string-join(
for $doc at $counter in $search-this-partner/event
order by $doc/EventStartDate/@date descending
return xdmp:quote(json:transform-to-json($doc, $config)),","),
"]}")
Is it possible to specify which nodes and the format I want to convert, still
using transform-to-json, or do I need to write a custom output myself?
