Luke,
You'll probably find this information useful:
Binding XML to Java
< http://www.theserverside.com/tt/articles/article.tss?l=Bindi ngXMLJava>
Except for complex types with mixed content, EMF will generally format
the result as well. By default it will be an indented format, but you
can turn that off to have more like the first version without any
unnecessary white space.
For an XML Schema based model, the root of your resource will consists
of a DocumentRoot instance that will have a getXMLNSPrefix map which you
can populate direct with any xmlns declarations you might like to see.
Follow these tutorial steps for your schema to give it a try:
Tutorial: Generating an EMF Model using XML Schema
< http://dev.eclipse.org/viewcvs/indextools.cgi/*checkout*/org .eclipse.emf/doc/org.eclipse.emf.doc/tutorials/xlibmod/xlibm od.html>
An editor is generated as well, but we won't be supporting forms
generation until the current release. If you invoke Generate Test Code,
you'll get a *.tests project with JUnit tests as well as an
XyzExample.java that shows how to read and write instances stand alone.
The only tool that I know of that's capable of preserving your exact
formatting (even DOM won't do that) is the structured text (XML) editor
in the web tools project, but it's just an enhanced DOM, so that might
not meet your needs either.
