Upload binary file through framework

[jeet1212]

While uploading a binary file. it is giving error in request.xqy.

(:Load All Request Fields:) for $j in xdmp:get-request-field($i) let $filename-key := fn:concat($PARAM-FILENAME-PREFIX,$i) let $x := if(fn:matches($j,"^({|[)*(}|])$","mix")) then .....

in fn:matches() it is giving error as $j should be string not binary.

Thanks & Regards, Indy
