Enforcing XML contentType while uploading MarkLogic

Question

While uploading files with a clear .xml extend via a http-server made. MarkLogic saves it in my local database as a .txt file.

This means I can't run my query's against it.

Uploader:

declare function local:uploadFile()
{
let $filename := xdmp:get-request-field-filename("upload")
let $file := xdmp:get-request-field("upload")
let $collection := "semansysdocs"

return
  xdmp:document-insert(
    $filename,
    $file,
    xdmp:default-permissions(),
    (xdmp:default-collections(), $collection)
  )
};

As you can see, is this a XBRL document, which is roughly XML+. I can't specify the contentType within the xdmp:document-insert(), you guys any idea how to enforce a XML contentType?

Answer 1

When using code below, some known content types / file extensions will be ingested as you would expect:

let $file := xdmp:get-request-field("upload")
let $filename := xdmp:get-request-field-filename("upload")
let $contenttype := xdmp:get-request-field-content-type("upload")
let $extension := fn:replace($filename, '.*\.', '')
let $insert := switch ($contenttype)
    case "text/xml"
    case "text/xhtml"
    case "text/csv"
    case "text/plain"
    case "application/json"
        return xdmp:document-insert($filename,xdmp:unquote($file))
    case "application/octet-stream"
        return switch ($extension)
        case "gpx"
            return xdmp:document-insert($filename,xdmp:unquote(xdmp:quote(binary{xs:hexBinary($file)})))
        default
            return xdmp:document-insert($filename,$file)
    default
        return xdmp:document-insert($filename,$file)
return fn:concat("file '",$filename,"' uploaded, contenttype: ",$contenttype," extension: ",$extension)

Result of uploading various file formats

Answer 2

Before inserting it, you need to parse it back into XML (it was text coming over the wire, I guess). This is done with xdmp:unquote()

....
let $file := xdmp:unquote(xdmp:get-request-field("upload"))
....

Please note that the above is simplified. You may need to set other options based on your need - see the docs for details.

Separate from that - you state the the document is .txt .. I assume that you mean it is a text node. MarkLogic will not add any .txt to the name of a file in the URI. If you see that, then that is what is being sent in the request field.
