XML Entities and DTLs

[Sean]

We are using DTLS to transform an EnsLib.EDI.XML.Document object to an EnsLib.HL7.Message.  We are experiencing issues with source values that contain XML entities.  We could ZCONVERT each value that we map to convert the entities into characters but I would like to avoid adding a ZCONVERT to every possible mapping that could contain a string.  Is there a setting I could change on EnsLib.EDI.XML.Document that would do this automatically when I do a GetValueAt.  Any other possible solutions?

Thanks
Sean

You haven’t said what version of Ensemble you are on or what patches to XML VDoc are applied.

 

We did add an output flag to GetValueAt:

 

o : output unescaped - for instance don't change < to &lt;

 

For instance,

 

GetValueAt(“/”,”o”)

 

You might need JSL4239 which is in a forthcoming release of Ensemble:

 

Fixed ProdLog #110819: XMLvDoc: option "o" not applied correctly to special

characters

...

 

In DOM path code, found case where $$$CONDXMLESCAPE($g(pFormat),...) was not

called.

 

In Prop path code, change propParsePath to use pFormat and in a couple of cases

where we are dealing with a single value from the Prop cache, we change code to 

invoke $$$CONDXMLESCAPE macro.

 

Regards,

Jonathan

I believe that GetValueAt is a method on EnsLib.EDI.XML.Document.  If you create your own document as a subclass of EnsLib.EDI.XML.Document you can override GetValueAt and do anything you need to.

Class MyDocument Extends EnsLib.EDI.XML.Document 

{

Method GetValueAs(

pSegmentPropertyPath As %String,

pSeparators As %String,

Output pStatus As %Status) As %String

{

// First do whatever the default method does and get the base value

Set tValue = ##super(pSegmentPropertyPath, pSeparators, .pStatus)

Quit:$$$ISERR(pStatus) tValue

// Now do whatever you need to to tValue before you return it

// you can alter pStatus to return an error if need be as well

:

Quit tModifiedValue

}

}

Great solution.  We are actually subclassing EnsLib.EDI.XML.Document currently. Very simple fix.

Thanks
