[sowmyaraj53@xxxxxxxxx (sowmya )]

Hi 

  I want to perform some operation on all the elements in each of the 
diagram files for all the project in the workspace. 
I am able to get the diagram and the model filename as a IResource 
object.How could i get the editPart from the filename
  

for now i have pasted the code by which i can get the diagram/model 
fileName



    IProject[] projects = null;
    IProject p = null;
    IFolder file = null;
    IResource[] members = null; 
    IResource[] newFile = null;

   IWorkspace workspace = ResourcesPlugin.getWorkspace();

   // gets all the projects in the workspace 	
   projects = workspace.getRoot().getProjects();
	for (int i = 0; i < projects.length; i++) {
           p =  projects[i];  
	}
	try {
             // gets all the folders in the project
		members = p.members();
	}catch (Exception e){
		
	}
		
	file = (IFolder) p.findMember("<myrequiredfolder>");
		
	try {
	   newFile = file.members();
	}catch(Exception e){
