      Currently I am working on a project requiring conversion of xml to hl7.  I have approached this in two ways, both using a valid schema (xsd):

      1.  Xlate

      2.  TCL ( using grm for the DOM tree and then just building the HL7 in-line)

      Messages are significant in size ( > 4Mb ) with multiple images ( base64 ) eg: ( excerpt from .xml ) being converted to multiple OBX’s in the HL7

      The issue comes into play with larger Images, It can take up to 4hrs to process a single message, however, if dealing with small images, I get sub-second response.

      Any help or direction on what may be causing this issue would be appreciated

            4 Hours is a LOT!

            We (CL 5.5) had a problem with XSDs when maxOccurrences wasn’t ‘unbounded’, but a value like ‘99999’. Testing an XML or translation on it was impossible. After changing all specific values to ‘unbounded’, there were no more troubles.
