Ravi asked:
" how do we link one xml to another... so that i can fetch all the employees
belonging to a particular department"

I think you are trying to do a join, not a link. However, if you want to do
this, you can use XLink to link to multiple resources, but you will need to
transform the document if you want to dynamically constrain the link (for
example, "get all the employees that are not managers").

Here is an example (copied from the XLink recommendation)

<!-- First of all, set up the resources -->
<extendedlink xlink:type="extended">
  <loc xlink:type="locator"
	link:title="p1" />
  <loc xlink:type="locator"
	xlink:title="c1" />
  <loc xlink:type="locator"
	xlink:title="c2" />
  <loc xlink:type="locator"
	xlink:title="c3" />
... <!-- arc-type elements would go here -->
<!-- Now link from the parent to the children -->
<go xlink:type="arc" xlink:from="parent" xlink:to="child" />

The problem with the XLink approach is that all joins have to be explicitly
coded in the source documents. This is very inconvenient compared to SQL, so
I would recommend putting the documents into an SQL database and doing the
join there.
