T-SQL and XML output

So I have written on the joins and left joins etc.. for this xml project I am working on. However I am having some hell of a time with the XML portion. I can get all the data into a dataset. However I can't get the data to output the xml the way I would like to.

The TransactionTable left joins with the TimeEntry table on the transactionID . 1 to many the TransactionTable inner joins to the ClientTable 1 to 1

Data all comes out nicely with the left and inner join on my select statement. All data is there.

However I need it to output in the XML format I need. Can't figure out how to do it. Got close but everytime I get close I run into another roadblock.
