IBM Sterling Transformation Extender

Hi guys,

I am working on transforming a file from X12 (input) to XML(output). My output is required to have self closing XML tags (i.e. <element/>) when associated XML element is not evaluated. After doing dozens of research I found out that self-closing XML tags are not possible to output when using XML schema as the type tree. So, I instead, created a type tree by importing XML schema using classic validation. Using Empty property under Type Syntax, I was able to generate the self closing XML tags. However, I am running into a issue when XML tag is of complex type (when it has sub elements inside it - see below) and not of simple type.

...

<another_element></another_element>

<main_element>

 <element_1></element_1>

 <element_2></element_2>

 ...

</main_element> 

Currently, it is outputting <main_element></main_element> when its subelements are evaluated to NONE. I want it to output with self closing tag like so <main_element/>. 

Please note: that it is outputting self closing XML tags when element is a simple type (i.e. <another_element/>) but is not doing it for elements that have sub_elements. So, can anyone knows a solution or a workaround this issue? Much appreciated. 

I am using the following edition of ITX:

Version: 9.0.0.3
Build id: 21

Have you set the min range of the sub elements to 0?  Perhaps it is stuck at 1?

Thank you.

Hi Paul,

The subelements all have min range of 0. I forgot to include another sub element under main element in my original post. This is the snippet of correct version of my XML schema structure with ranges:

...

<another_element minOccurs="1" ></another_element>

<main_element minOccurs="1">

<sub_element minOccurs="0" maxOccurs="unbounded"> 

<element_1 minOccurs="0"></element_1>

<element_2 minOccurs="0"></element_2>

 ...

</sub_element>

</main_element>

Thanks

Fyi, the reason I am setting another_element and main_element minOccurs to 1 is because I want to see self-closing tag for those elements. I noticed that only when minOccurs is set to 1 will the Empty property work.
