hey there

ok using the sample logic of the attr type the logic of extension should be the same agreed?

OK

so to find a type i use the following within XML

Code:

FIELDVALUE(Root.XML.(XML.Element)"XML".(XML.attr)type);

However for and extension when I do the same

Code:

FIELDVALUE(Root.XMLNS.(XML.Element)"PORX_IN070103UK04".interactionId.(XML.attr)extension);

it fails

the portion of the message I am looking at is

Code:

<?xml version="1.0" encoding="UTF-8"?>
<PORX_IN070103UK04 xmlns="urn:hl7-org:v3" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" >
<id root="1234567"/>
<creationTime value="20041202105055"/>
<versionCode code="V3NPfIT3.1.07"/>
<interactionId root="2.16.840.1.113883.2.1.3.2.4.12" extension="[color=red]PORX_IN070103UK04[/color]"/>

Thanks In advance

when using XMLNS, you have to namespace qualify every element.

THX Jeff

So I would have to write the esql like this?

Code:

SET MSGTYPE = FIELDVALUE(Root.XMLNS.(XML.Element)"PORX_IN070103UK04".(XML.Element)"interactionId".(XML.attr)extension);

well i tried this and it still came up with

Code:

Failed to navigate to path element because it does not exist.

No.

I mean that for each element in your XML document that belongs to a namespace, you have to include a reference to that namespace in your ESQL.

oh doodoo i just realised yu mean this

Code:

urn:hl7-org:v3:

so it should be something like

SET MSGTYPE = FIELDVALUE(Root.XMLNS.(XML.Element)"urn:hl7-org:v3:PORX_IN070103UK04".(XML.Element)"urn:hl7-org:v3:interactionId".(XML.attr)extension);

as the trace looks like this

Code:

(0x01000000)urn:hl7-org:v3:PORX_IN070103UK04 = (
(0x07000012):xmlns = 'urn:hl7-org:v3'
(0x07000012)xmlns:xsi = 'http://www.w3.org/2001/XMLSchema-instance'
(0x02000000): = '
   '
(0x01000000)urn:hl7-org:v3:id = (
(0x03000000):root = '1234567'
)
(0x02000000): = '
   '
(0x01000000)urn:hl7-org:v3:creationTime = (
(0x03000000):value = '20041202105055'
)
(0x02000000): = '
   '
(0x01000000)urn:hl7-org:v3:versionCode = (
(0x03000000):code = 'V3NPfIT3.1.07'
)
(0x02000000): = '
   '
(0x01000000)urn:hl7-org:v3:interactionId = (
(0x03000000):root = '2.16.840.1.113883.2.1.3.2.4.12'
(0x03000000):extension = 'PORX_IN070103UK04'

the solution to my problem was 2 fold

firstly I added a RCD into the flow switching it back to normal XML

secondly the address to access the was set to be the following

Code:

SET MSGTYPE = FIELDVALUE(Root.XML.(XML.Element)"PORX_IN070103UK04".interactionId.(XML.attr)extension);

i feel as if i am floating now!
