Reports & Discoverer :: Excluding SQL Query Data When Linked With XML Query?

I have data in a table and another in XML file,I used SQL query to retrive the data placed on the table, and link this query with XML query that retrieves the data stored in the xml file. The data stored in the table and xml file sharing a key field, but the xml contents are less than what in the table.I want to show only the data shared between the two queries, how can I do that?

e.g.:

Table emp:

e_id | e_name | e_sal
023 | John | 6000
143 | Tom | 9000
876 | Chi | 4000
987 | Alen | 7800

XML File

<e_id>
143
876

So, I want the output to be:

e_id | e_name | e_sal | e_fee
143 | Tom | 9000 | 300
876 | Chi | 4000 | 100
