Hello
i go t a probelm with the ResourceEntityHandler. If i use the
ResourceEntityHandler in the open and save options, in ModelEditor
the Entities arent replaced correct;
example
DTD-File
<!ENTITY version "111">
<!ENTITY buildVersionDir "/develop/loc/v&version;/">
XML-File
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE build SYSTEM "build.dtd">
<model:Build xmlns:model="http://model.plugin.build.mainz.de.ibm.com">
<model:pathInfo>
<model:buildVersionDir>&buildCodeDir;</model:buildVersionDir >
</model:pathInfo>
</model:Build>
ModelEditor
public void createModel() {
resourceURI = EditUIUtil.getURI(getEditorInput());
// add URI to Build View Manager (for View)
ConfigurationManager.getManager().addConfiguration(resourceU RI);
Exception exception = null;
Resource resource = null;
editingDomain.getResourceSet().getResourceFactoryRegistry(). getExtensionToFactoryMap().put( "xml",
new XMLResourceFactoryImpl() {
@Override
public Resource createResource(URI uri) {
XMLResource result = (XMLResource) super.createResource(uri);
// ResourceEntityHandlerImpl resourceEntityHandler = new
// ResourceEntityHandlerImpl("_");
ResourceEntityHandlerImpl resourceEntityHandler = new
ResourceEntityHandlerImpl("_");
result.getDefaultSaveOptions().put(XMLResource.OPTION_EXTEND ED_META_DATA,
Boolean.TRUE);
result.getDefaultLoadOptions().put(XMLResource.OPTION_EXTEND ED_META_DATA,
Boolean.TRUE);
result.getDefaultSaveOptions().put(XMLResource.OPTION_SCHEMA _LOCATION,
Boolean.TRUE);
result.getDefaultSaveOptions().put(XMLResource.OPTION_SAVE_D OCTYPE,
Boolean.TRUE);
//
result.getDefaultLoadOptions().put(XMLResource.OPTION_USE_EN CODED_ATTRIBUTE_STYLE,
Boolean.TRUE);
//
result.getDefaultSaveOptions().put(XMLResource.OPTION_USE_EN CODED_ATTRIBUTE_STYLE,
Boolean.TRUE);
//
result.getDefaultLoadOptions().put(XMLResource.OPTION_USE_LE XICAL_HANDLER,
Boolean.TRUE);
result.getDefaultLoadOptions().put(XMLResource.OPTION_RESOUR CE_ENTITY_HANDLER,
resourceEntityHandler);
return result;
}
});
try {
resource = editingDomain.getResourceSet().getResource(resourceURI, true);
} catch (Exception e) {
.....
So if I load the XML-File with ResourceEntityHandler in the ModelEditor
buildVersionDir = 111/
that is wrong. but if i doesnt use the ResourceEntityHandler the
buildVersionDir is correct?
I must use the ResourceEntityHandler. Any ideas?

So you're using entities in the definition of other entities. I just
don't think the SAX callbacks provide enough details to try to
accurately record these things. I'll only see the expanded version and
have no idea how entity expansion arrived at the string.

Not really. The only places the entity hander are used is:
public void startEntity(java.lang.String name)
{
if (resourceEntityHandler != null)
{
text = new StringBuffer();
}
}
public void endEntity(java.lang.String name)
{
if (resourceEntityHandler != null)
{
resourceEntityHandler.handleEntity(name, text.toString());
}
}
So I imagined all they'd do is record things with no other effect.
Perhaps this is being invoked recursively, but I didn't think entities
nested...

So you're using entities in the definition of other entities.

Ok thanks
Is there a way to get the loaded Entities without the
ResourceEntityHandler, i mean from the editingDomain or the loaded
Resource? I tried to find them with the debugger. No luck

EMF just uses SAX to load so if there isn't a way to do it with SAX,
there isn't a way. I don't think you can even do what you want with DOM
for that matter, so that should be a good indication that it's a hard
problem.
