Progid to launch an xml file in MS Project 2010 client.

Question

For any xml  file the mso-application declaration with progid “Word.Document” allows this xml file to open using MS Word when
double clicked on the file. In the similar manner, I am looking to open the XML file obtained from MS Project. I tried to add
mso-application declaration with progid “MSProject.Project” ,
but it opened up with normal text editor whereas I was expecting in MS Project 2010 client application.
After reading different articles, I come to know that these progid s will be present in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared\XML\ProgIds. Unfortunately I did not find any entry for MS Project. Hence, I tried to add a string key
MSProject.Project here and restarted the OS. After restart, if I double click the xml file with MSProject.Project as progid under mso-application declaration, it still opened with text editor but not in MS Project 2010.
Can you please guide me - how I can open an xml file in MS Project just by double clicking on the file.

Bharath --
Have you tried the following:
Launch your Windows Explorer software and navigate to the folder containing the XML file.
Right-click on the XML file, select Open With on the shortcut menu, and then click Choose Default Program on the flyout menu.
In the Open With dialog, click the Browse button.
Navigate to the folder where the Microsoft Project 2010 EXE file is located.
Select the Microsoft Project EXE file (it is called WINPROJ.EXE) and click the OK button.
If you notice in the Open With dialog, all of the default programs listed are XML editors.  I suspect this is why you cannot do what you want with an XML file, since Microsoft Project is not an XML editor, but perhaps the above steps will work for you. 
Hope this helps.
