Need example for class method within EnsLib.EDI.XML.Prop (choiceGetCount())

#XML #Caché

Hello,

 

I've been manipulating XML objects via Cache, but have had some difficulty understanding how to use the following method detailed within EnsLib.EDI.XML.Prop:

Method choiceGetCount(Output pCount, pDOMPath As %String, pRef As %String) As %Status 
 

From what I've read when walking through the code for this method, it appears to count a listing of repeating XML elements. However, despite my attempts to search for examples or attempts to implement this function, I am unable to do so.

 

Would anyone have any examples or ideas? Perhaps, at least, can someone tell me if I am using this function for its intended purpose?

 

Thanks,

-Mike

Creating a sample EnsLib.EDI.XML.Document class:

set writer=##class(%XML.Writer).%New()
set writer.Indent=1
set status=writer.OutputToString()
set status=writer.StartDocument()
set status=writer.RootElement("root")
set status=writer.Element("RepeatingElement")
set status=writer.WriteChars("Content")
set status=writer.EndElement()
set status=writer.Element("RepeatingElement")
set status=writer.WriteChars("Content")
set status=writer.EndElement()
set status=writer.EndRootElement()
set status=writer.EndDocument()
set xmlstring = writer.GetXMLString()

set xml = ##class(EnsLib.EDI.XML.Document).%New().ImportFromString(xmlstring)

As a test, I'm trying to call inherited function "choiceGetCount()" from parent class EnsLib.EDI.XML.Prop:

write xml.choiceGetCount(1, "/root", "RepeatingElement") // outputs status of 1

So, I'm not too clear on how this function works, or if I'm using it as intended. I'm attempting to output a listing of how many times a selected XML element repeats ("RepeatingElement" in this example).  Again, here is the function signature (I think "As %Integer" was accidentally omitted for formal parameter 'Output pCount'):

Method choiceGetCount(Output pCount, pDOMPath As %String, pRef As %String) As %Status

Thanks,

-Mike
