Hello,
I have defined a simple metamodel using Ecore and I have generated the
plugins. When I create a model conforming to that metamodel, the
serialized thext looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<Library xmlns="http://sLibMM" xmlns:_="" _:name="theLibrary">
<Book ref="1" available="no">
<title>myBook</title>
<author>me</author>
</Book>
<Book ref="2" available="no">
<title>yourBook</title>
<author>you</author>
</Book>
</Library>
And I would like it to be:
<?xml version="1.0" encoding="UTF-8"?>
<Library name="theLibrary">
<Book ref="1" available="no">
<title>myBook</title>
<author>me</author>
</Book>
<Book ref="2" available="no">
<title>yourBook</title>
<author>you</author>
</Book>
</Library>
That is, I don't want the xmlns attribute in my XML.
Any idea how can I do it?
I attach my Ecore metamodel.
Thanks in advance.
Ander

Anders,
Hmmm. Maybe there needs to be a document root too... I'd have to try
and am about to fly...
I'd suggest creating a small schema as a starting point. Note that you
can ever export your model to an XML Schema (from the Generator menubar
item) as a starting point.
