Hi,
Can an XML injection accept multiple XML documents as input? My problem is to correlate multiple XML input documents (based on same metamodel) into lesser number of output XML documents based on some parameters in the input. For this I need to input multiple XML files that need to be correlated to the ATL transformation. How can I do this?

Thanks Sylvain,
does that mean that I use Java code to extract the individual XML documents after this step:
4. Target XMI Documents -> Target XML Ecore Documents
Java: Extract individual XML Ecore Documents
5. Iterate: One XML Ecore Document -> One Target XML
When I go throuhg code of the XML Extractor, there is a similiar piece of code in the "extract" function which seems to be doing the same thing (pasted below). Or I am mistaken? I dont mind using Java to extract, but I want to be sure there is no API already existing :
Extract:
public void extract(IModel sourceModel, OutputStream target, Map<String, Object> options)
throws ATLCoreException {
PrintStream outStream = new PrintStream(new BufferedOutputStream(target));
outStream.println("<?xml version = '1.0' encoding = 'ISO-8859-1' ?>");
EMFModel xmlModel = (EMFModel) sourceModel;
EClass rootClass = (EClass) xmlModel.getReferenceModel().getMetaElementByName("Root");
Set<EObject> rootElements = xmlModel.getElementsByType(rootClass);
serializeContent(
rootElements.iterator().next(),
xmlModel, outStream, "");
outStream.close();
}

It turns out there is a bug in the XMLExtractor code, which I fixed by changing the code as below:
Extract:
public void extract(IModel sourceModel, OutputStream target, Map<String, Object> options)
throws ATLCoreException {
PrintStream outStream = new PrintStream(new BufferedOutputStream(target));
outStream.println("<?xml version = '1.0' encoding = 'ISO-8859-1' ?>");
EMFModel xmlModel = (EMFModel) sourceModel;
EClass rootClass = (EClass) xmlModel.getReferenceModel().getMetaElementByName("Root");
Set<EObject> rootElements = xmlModel.getElementsByType(rootClass);
//Inserted code
Object eArray = rootElements.toArray();
for (int i=0;i<rootElements.size();i++){
//serializeContent(
//rootElements.iterator().next(),
//xmlModel, outStream, "");
serializeContent( (EObject)eArray[i],xmlModel,outStream,"");
}
outStream.close();
}
