How to Dump XML data into table

Question

Hi All,
We have one schema on a server.
We have created the same schema with only table structures on another new server.
Now we got the data from the original schema as XML files corresponding to each table.
For Example, we have Employee table created newly on a new server. Now we have the XML file which has Employee data. We have to dump this XML data into new EMPLOYEE table.
We have to dump these XML files data into corresponding tables.
How can we achieve this?
Please help me..
Thanks in advance
