Does Node UUID get propagated from Staging to Production

Question

Hi,
We have the following requirement -
We have a folder which contains list of articles in Content Repository.
The requirement is to select the articles from the folder, and display it in a certain order.
Preferred solution is XML based, where we just specify the list of items in the order in which they are to appear.
We did think of a solution where, we will list down all the UID of the nodes that should appear in the portlet in the same order in XML. And in the JSP retrieve the node based on the UUID and display all its relevant properties.
However I just had one concern on this. The custom will always manipulate the XML on Staging and then propagate onto production. So in that case, the Node UUID that is obtained from Admin Console in Staging - Once propagated does it remain same?
So will the Staging XML with Staging values of NODE UID's have tp be manipulated to point to Production UID's or
Does the UUID value in staging get propagated to PRODUCTION. SO that the same XML can be used across. Or is a new SET of UID's are created for PROD env.

Hi Deepak,
Thanks for your inputs.
You mentioned that we create a property in the content type that specifies the order.
If I understand it clearly, if we create 2 properties 1. to-be-published (boolean) and 2. posted-date
and instruct the person doing content management that
1. Select the items using the to-be-published property (Content selector will select all nodes on the basis of this property)
2. The items will be sorted on the basis of posted-date (Descending order)
Pls. confirm, if this can be the approach.
Alternatively,
As end user was insisting a XML based approach, how about creating a property - Post-Id (User will have to specify a unique ID) and in the XML just specify the ID. But what I dont get here is, how will the nodes get retrieved in first place.
Thanks,
