Create an XMLNSC Tree in ESQL

CREATE LASTCHILD OF OutputRoot DOMAIN 'XMLNSC' NAME 'XMLNSC'; 
CREATE LASTCHILD OF OutputRoot.XMLNSC NAME 'FileData'; 
CREATE FIRSTCHILD OF OutputRoot.XMLNSC.FileData NAME 'BlobPayload' value InputRoot.BLOB.BLOB; 
CREATE LASTCHILD OF OutputRoot.XMLNSC.FileData NAME 'Filename' VALUE InputLocalEnvironment.File.Name;
CREATE LASTCHILD OF OutputRoot.XMLNSC.FileData NAME 'Filedir' VALUE InputLocalEnvironment.File.Directory;

The above code will create the following XML payload.

<FileData>
   <BlobPayload>XXX</BlobPayload>
   <Filename>YYY</Filename>
   <Filedir>ZZ</Filedir>
</FileData>
