You're very close, Tim. But as you've found out, a direct element
constructor "<binary>..." just creates an element named binary, not a
binary node. That's legal XQuery, but not very helpful.
Instead, I believe you want the computed constructor for a binary node
(aka "binary node constructor"). This is a MarkLogic Server extension,
because the XQuery 1.0 data model doesn't include the concept of a
binary node.
Anyway, in either 0.9-ml or 1.0-ml you can write:
binary { $content }
Note that the binary node constructor can also handle xs:base64Binary
directly:
binary { xs:base64Binary("ABCD") }
You can read more about binary constructors and other XQuery
enhancements in the XQuery Reference Guide:

Hi all,
I am trying to upload files (binary and other) to database but need your help.
Using html forms and xdmp:get-request-field together with xdmp:document-insert
I succeed.
But I had not the same result using xforms. In xform, the binary data is store
in xml instance within an base64Binary element.
On the server side I decoded data and try to store like this:
let $contentToStore := xs:hexBinary(xs:base64Binary($contentEncoded))
let $work := xdmp:document-insert($doc, $contentToStore )
but get error $contentToStore is not a node. If I try to create an node using
the data as
let $contentToStore2 :=<binary> {$contentToStore}</binary> the data is stored
as text BUT not binary.
The function document-insert doesn't have options for setting data format. The
documentation says that the root element of the node defines the data format
but I couldn't find any example how to set that.
How can I create a binary node from the hexBinary data ? Or is there another
way for uploading files from xforms and base64Binary encoded data?
Any help is appreciated.
