Hello everybody,
I want to know whether I can generate an xsd(xml schema) from an xml
file on the fly (at runtime).
I'll elaborate on that, I have an xml file and I want to generate a
schema out of it, at runtime. If I make any changes to the xml file
corresponding changes should be done to the schema file.
More precisely if there is a tag in the xml file say grid and it has
properties and childTags a its child nodes. properties will hold several
<property> nodes as child nodes. and childTags will specify which nodes
will serve as the child nodes. Now in the schema file I'll have a
xsd:ComplexType for every tag and xsd:element for every property.
I have achieved this using the DOM API. Is there a better way of doing
this.
Can EMF help me to generate from an xml(not xsd) file a schema file at
runtime.
Here runtime means when my plugin is activated and I generate a new JSPX
project having nature JSPXNature. At the Eclipse conference (JAX India) I
attended in Bangalore, Chris mentioned that this may be done using EMF.
Waiting fervently for your valuable inputs.
Thanking you in advance.

Sourabh,
I think WTP might have a facility for deducing an XML Schema given an
XML instance file, but I don't know of any others. You might find this
paper handy, because it shows how you can load arbitrary XML as an EMF
model:
Binding XML to Java
< http://www.theserverside.com/tt/articles/article.tss?l=Bindi ngXMLJava>
Given an Ecore model, it's possible to export it as an XML Schema. I
demonstrated how to do that in this recent webinar:
