Hello,

We would need to convert a message from the following class:

Class Mensajes.Request.Laboratorio.HL7Request Extends Ens.Request [ ClassType = persistent, ProcedureBlock ]
{ Parameter RESPONSECLASSNAME = "Mensajes.Response.Laboratorio.ACKResponse";

Property mensaje As %XML.GlobalCharacterStream(CONTENT = "MIXED");

Property idPeticion As %String(MAXLEN = "");

Property ExpedienteUsuario As %String(MAXLEN = "");

Property MessageId As %String(MAXLEN = ""); Property ContentType As %String(MAXLEN = "");

to a Request message which is composed by hl7 segments:

Class Mensajes.Request.Laboratorio.ServicioRecepcionDatosPruebaRequest Extends Ens.Request [ ProcedureBlock ]
{ Parameter RESPONSECLASSNAME = "Mensajes.Response.Laboratorio.ServicioRecepcionDatosPruebaResponse";

Property MSH As hl7.MSH.CONTENT; Property NTE As list Of hl7.NTE.CONTENT;

Property ORMO01PATIENT As EsquemasDatos.HUC.hl7.ORMO01.PATIENT.CONTENT;

Property ORMO01ORDER As list Of EsquemasDatos.HUC.hl7.ORMO01.ORDER.CONTENT;

Property SFT As list Of hl7.SFT.CONTENT; Property MSA As hl7.MSA.CONTENT;

Property ERR As list Of hl7.ERR.CONTENT;

We currently send the following message using HTTP via SOAPUI

In the process we use the following code to get just the ORM, and use the ITB function to try to parse it from XML to HL7:

  set context.mensaje = $PIECE($PIECE(context.mensaje,"</SOAP-ENV:Body>"),"<SOAP-ENV:Body>",2)
 
  $$$LOGINFO("mensaje sin cabeceras: "_context.mensaje)
 
 
  set mensajeXML = ##class(%GlobalCharacterStream).%New()
 
  do mensajeXML.Write(context.mensaje)
 
 
  while mensajeXML.AtEnd=0 {
   set linea = mensajeXML.Read()
 
  }
  do mensajeXML.Rewind()
 
  $$$LOGINFO("linea: "_linea)
    
 
  set context.mensajeHL7 = ##class(EnsLib.HL7.Message).%New()
  set context.mensajeHL7 = ##class(ITB.HL7.Util.Convert).XMLToER7(mensajeXML, .status,"2.5")
    
    
  //$$$LOGINFO("status: "_status)    
  $$$LOGINFO($system.Status.GetErrorText(status))

And we observe in the trace:

And the exception is:

In both cases the mensajeHL7, is empty:

We have also read:

How could we parse a XML message and convert it ➡️ into a request message which is composed by hl7 segments?

Hi Yone,

Try to append in the bigginer of you XML Strign the XML declarion:

In the line:

do mensajeXML.Write($zcvt("<ORM_O01>........

Try:

do mensajeXML.Write($zcvt("<?xml version="1.0" encoding="utf-8"?> <ORM_O01>........

And check if had some character that can cause the <SINTAX > error in the cos.
