Load portion of xml file [message #425199]

Hi All,

Is there any way to load portion/partial xml file with EMF?

Say for example,
<person>
<name>XYZ</name>
<address>
<houseNo>1</houseNo>
<streetNo>4</streetNo>
<society>ABC</society>
<city>Bangalore</city>
<state>Karnataka</state>
</address>
</person>

How can I load just <address> portion of the xml? The reason is there is
no schema definition for the rest of the xml document. And entire document
is very large. The above is just example for simplicity.

Thanks in Advance.
Sun

Sun,

No, there's not, but if you load with the resource created by
GenericXMLResourceFactoryImpl you should be able to load the whole file
and extract the part you're interested in.

Ed,

Can you give some example code for using the GenericXMLResourceFactoryImpl?

For this example lets say there is a file called address.ecore which
define the schema. And person.xml is the xml file from which address needs
to be loaded. After modification when I save the resource, will it update
appropriate portion automatically?

Regards
Sun

Sun,

You just register it and use it like any other resource factory, i.e.,
just like the one that's generated for your schema-based model. Have a
look at its createResource method and compare that to the one for your
generated model. And yes, it will serialize changes properly. Have a
loot at this article to understand how it works:
