#XML

Dear,

I'm trying to configure a new interface that reads HL7, transform them into FHIR messages and then send POST or PUT or DELETE depending on HL7 doc type.

1-I added an HL7 TCP service that reads ADTs messages

2a-Send ADTs to a process to transform them into SDA (using the following command: do ##class(HS.Gateway.HL7.HL7ToSDA3).GetSDA(request,.con))

2b-Extract the patient MRN and add it to the AdditionalInfo property (using the following request message class: HS.Message.XMLMessage)

I have a registered object class that extends %XML.Adaptor and I want to convert an object of it into canonical XML.

From reading the documentation and some trial and error, it seems like I would need to use %XML.Writer to write the object to XML first using the RootObject() method, then read it with %XML.Reader, and then use the Canonicalize() method of %XML.Writer to write it out again.

Is there a better approach?

Hi all,

I'm trying to convert a HL7 section to a XML or JSON string.

We need to save the content of PID section into a SQL Column, therefore we need to convert it into a XML o JSON string

is there any easy way to convert it?

I've tried to convert it directly into a DTL, but all my attempts have been unsuccessful

Best regards,

Francisco Lopez

I'm looking for any codes that match my parameter that we have received since 1/01/2020 based on the FromTime, EnteredOn or Status (if both are empty).

(Problem[Problem/Code='%1' and FromTime>"2020-01-01"]) | (Problem[Problem/Code='%1' and (count(FromTime)=0 or FromTime="") and EnteredOn>"2020-01-01"])
| (Problem[Problem/Code='%1' and (count(FromTime)=0 or FromTime="") and (count(EnteredOn)=0 or EnteredOn="") and Status/Description="Active"])

This works like a charm with standard XPATH query tools but HS does not like it.

We have a data transformation where source is object collection (populated from a json file) and target is EnsLib.EDI.XML.Document.

If source file is large enough, transformation fails and we get <store> error and I quickly found this:

https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=EBPLR_DTL_foreach which at the bottom in "Avoiding <STORE> Errors with Large Messages" section tells to:

Hi

I need to query my messages and filter by a XML node.

As part of a process to generate FHIR XML bundles from HL7 messages, I have a subtransform transforming segments of an MDM_T02 message into a section of XML (EnsLib.EDI.XML.Document). So far this has worked well although I've encountered strange behaviour when making use of an xmlns attribute, whereby the attribute's name is duplicated despite the schema and DTL editor displaying it correctly.

Hi everyone,

I'm working on a DTL that transforms an HL7 message (EnsLib.HL7.Message) to an XML document (EnsLib.EDI.XML.Document).

The target XML is based on a custom schema and has an element like:

<xs:element name="deceasedDateTime" type="xs:dateTime" nillable="true"/>

Is there a generic process for "walking" the structure of a virtual document - eg an HL7 message (EnsLib.HL7.Message) or an XML document (EnsLib.EDI.XML.Document).

At least we'd want to be able to visit all "nodes" (HL7 fields or sub-fields, XML nodes) in the virtual document and be able to work out/generate the Property Path (so we could call "GetValueAt").

We can just about come up with something generic for HL7, since it only nests down to 4 levels within each segment, though we're using numeric Property Path's at that point rather than symbolic ones (MSH:1.3 etc).

I have a scenario where I send a GET request to a broker and receive a FHIR response. When I attempted to use the built-in InterSystems functions to convert this FHIR response into SDA, the transformation failed—likely because it is not a standard FHIR request.

How should I handle this situation? Is there a recommended approach to processing FHIR responses in this context?

We are using a DTL transformation to take HL7 and transform into custom XML. But the nodes in the resulting XML are appearing out of sequence - and therefore failing validation against the schema.

The XSD schema for the XML looks fine when imported into Ensemble: root node in the XSD looks like this:

And shows in Ensemble like this:

Hi, I am coming unstuck with a current mapping from HL7 to XML using the DTL editor with an XML schema (imported by XSD).

My output keeps prefixing the elements with "xsd_2" despite this not being defined in the targetnamespace within my XSD file.

Would anyone have any idea as to where this is creeping in? Any advice would be greatly appreciated.

My XSD namespace etc are setup as follows:

I'm attempting to build a fairly complicated object graph, with nested objects and collections, in order to create a FHIR bundle.

In its most basic form there is a <bundle></bundle> element that represents the root, and there can be a number of nested <entry></entry> child elements.

I'm attempting to represent this as such:

I'm attempting to import all the FHIR XSD files provided by http://hl7.org/fhir but get the immediate and unhelpful error message:

I've tried different versions of EOLs to no avail. Any idea what this error could mean?

Here's the XSD I'm trying to import:

<?xml version="1.0" encoding="UTF-8"?>
