We are receiving a Base 64 report on an HL7 message but the source are sending on the OBX-5 a Line Feed at the end. He is not able to remove the Line Feed and we want to do it in Cloverleaf . How we can do it in tcl or xlate?
Do you have an example message? Is the line feed part of the encoded characters, or is it after? Is Cloverleaf decoding the base64 or is it being passed to another system? This should be easy to do in TCL.
If you’re just decoding the base64 data and not passing it anywhere you may not need to remove the linefeeds. The decode will ignore them, and they shouldn’t affect your field lookups since they are using \r and | as delimiters. If you do want to remove the linefeeds, I think you could do something like this:
<pre>set msg [msgget $mh]
set msg [string map { \n “” } $msg]
set ctr_val [msgmetaget $mh “USERDATA”]
set segmentList [split $msg \r]</pre>
