How do I change XML files programmatically? [message #901083]

To finish the task I am working on, I need to programmatically change the version, namespace, and schemalocation of a XML file. Does anyone know how to do that? What APIs can I use? Would very appreciate if any response!!

More specific, the file needs to be changed looks like this:

<entity-mappings version="2.0" xmlns="AAA" xmlns:xsi="..." xsi:schemaLocation="AAA .../xml/ns/persistence/orm_2_0.xsd">
</entity-mappings>

I need to programmatically change the file to a XML file as this:

<entity-mappings version="2.4" xmlns="BBB" xmlns:xsi="..." xsi:schemaLocation="BBB http://www.eclipse.org/eclipselink/xsds/eclipselink_orm_2_4.xsd">
</entity-mappings>

You can see I need to change the value of the following elements:

- version
- xmlns
- xsi:schemaLocation

Nan,

Sounds like something that would be pretty easy to do with a DOM.

Thank you Ed! Could you give me some examples? I am not so familiar with Eclipse + XML.

I don't think you need any Eclipse-specific tools for the simple things
you've described. Just DOM which comes with the JDK.

You can also try xml beans for more sophisticated handling. xml beans is like JAXB and binds xml documents to Java object which makes manipulation easy.

i.e. setNamespace() will set the name space.
