#Ensemble #Business Operation #Business Process (BPL) #DTL #Object Data Model #XML

I am trying to transform an Enlib.EDI.XML.Document through aXLT I know how to trans form the xml document  through a xlt stylesheet but been trying to get an Enlib.EDI.XML. Document from a procees by creating aoperation that will do the transformation of this to file if this can be done in a process all ideas welcome  so far I have come to this and I keep getting an error

:ERROR{ERROR #5002: Cache error: <PROPERTY DOES NOT EXIST>zXMLTOJson+6^TestEnvironment.Custom.GENERAL.CUSTOM.XLT.XMLToJsonOperation1.1 *Parameters,EnsLib.EDI.XML}

You're getting an error:

:ERROR{ERROR #5002: Cache error: <PROPERTY DOES NOT EXIST>zXMLTOJson+6^TestEnvironment.Custom.GENERAL.CUSTOM.XLT.XMLToJsonOperation1.1 *Parameters,EnsLib.EDI.XML}

Which means :

  • Class is EnsLib.EDI.XML
  • It does not have Parameters property
  • Error is found in the 6th line of zXMLTOJson routine in TestEnvironment.Custom.GENERAL.CUSTOM.XLT.XMLToJsonOperation1.1

6th line is probably this:

 Set tSC = ..Transform(tInput,tSSKey,pRequest.Parameters,.tOutput)

and pRequest object (of EnsLib.EDI.XML class) does not have Parameters property. Your call should probably be:

 Set tSC = ..Transform(tInput,tSSKey,pRequest,.tOutput)

Thanks for the advice have changed my code but come to a problem while reading my stream as there seems to an error with the XSLT XML Transformer Error: SAXParseException  I do not seems to see what the problem is as I tested my XLT with the XLT Transform Wizard and it all worked fine could you please have a look at the xml and the XLT and see if you can spot where I am going wrong thanks in advance

Here's the code I ran:

Class User.XMLTest
{

/// do ##class(User.XMLTest).Test()
ClassMethod Test()
{
    set source = ..GetXData("Source")
    set xslt = ..GetXData("XSLT")
    #dim result As %Stream.Object
    set sc = ##class(%XML.XSLT.Transformer).TransformStream(source, xslt, .result)
    
    do result.OutputToDevice()
}

ClassMethod GetXData(name) As %Stream.TmpCharacter [ CodeMode = expression ]
{
##class(%Dictionary.XDataDefinition).IDKEYOpen($classname(), name).Data
}

XData Source
{
Your Message
}

XData XSLT
{
Your XSLT
}

}

and here's the result:

{
"Message" :
{
"Header" :
{
"Code" : "HOT",
"Date" : "2017-12-08 11:22:34.658"
}, "Body" : [
 
{
"Code" : "HOT",
"Name" : "SIDE",
"Type" : "AADULT",
"Sec" : "MSec",
"ardge" : "Adult",
"Nder" : "F",
"TBC" : "21",
"BO" : "14",
"DBOC" : "0",
"LBC" : "5",
"AB" : "2"
},

...

Check %objlasterror and also check your XML encoding, there may be problems if your encoding does not match declaration.

@Eduard Lebedyuk

yes that the expected results even if you can not move the last two elements to be last just making something similar might help
