Reducing Redundancies In XML Output

Having difficulty achieving an end-result in transforming the results of a rowset query into XML.

Here is simplified test code that displays my problem:

declare @TimesheetHdrs table (EmpID int,EntryYear smallint,EntryPeriod tinyint,AdminNotes varchar(max),UserNotes varchar(max))
declare @TimesheetDtls table (EmpID int,EntryYear smallint,EntryPeriod tinyint,ProjCode varchar(25),ActCode varchar(25),ExpendCode varchar(10),EntryDate date,EntryQty decimal(7,2))
declare @Projects table (ProjCode varchar(25),ProjName varchar(200))

[Code] ....

The result of the above code is the following:

Code:
<root>
<timesheet empid="1" entryyear="2012" entryPeriod="1" adminnotes="These are the admin notes" empnotes="These are the user notes">
<project projnum="TestProject" projname="The really big project for our best customer">
<activity actcode="000103020200302302322" actname="Demolish the 55th story of the main tower">

[Code] ....

Notice how there is a tremendous amount of redundancy in the XML. I was hoping to come up with an XML result of the following, which transmits the same data, without the redundancies.

Code:
<root>
<timesheet empid="1" entryyear="2012" entryPeriod="1" adminnotes="These are the admin notes" empnotes="These are the user notes">
<project projnum="TestProject" projname="The really big project for our best customer">
<activity actcode="000103020200302302322" actname="Demolish the 55th story of the main tower">
<expenditure expcode="1" expname="Regular Hours">
