Hi,
Can anyone how we can control the element ordering in EMF Serialization,
e.g I have the following EMF model class,
├───Paragraph
│ ├───bullettedText (0..*)
│ ├───formattedText (0..*)
│ ├───heading (0..*)
│ ├───table (0..*)
│ └───text (0..*)
The following are some samples that shows what I want to do when
serialization happens
e.g - 1 : ExamplePara1(text,heading,formattedtext)
e.g. - 2 : ExamplePara2( text,heading,text,formattedtext,text)
e.g. - 3 :
ExamplePara3(text,heading,text,formattedtext,text,formattedt ext,bullettedtext,text)
What I am trying to achieve is that I want the any reference features to
occur in any order and also in mixed format.
Summary I don't what the element to be grouped within a parent as all
texts together , all paragraph together etc., i need to them to occur in
the order i create then in the Editor
Is there anyway we can do this in EMF Serialization. Any property we need
to set ? I tried with "ordered" property of the Class but in vain.
Thanks.
Kamesh

Try defining an <xsd:complexType> with mixed="true". This will produce
a model that supports what you show above. This will likely prove useful
Binding XML to Java

Be sure your complex type allow that mixed order.

You'll have a much easier time if you write a small XSD, generate your
Ecore model from that, and then use that as the basis for what you're
trying. The odds of doing it correctly from scratch directly in Ecore
seem low.

Did you read the article to understand how mixed text works?

It sounds okay but likely you missed something... Best to create a
working schema-based example...
