Copy a table

[JJKazJr]

This seems really easy, but I can't seem to get it to work. Lets say I have a dataset that I am filling with all the information that I will use later named rs. Now I want to add data to rs from an xml file. So far I tried to just read the file into rs, but since rs already has data in it, it cannot fill with a multitable xml. So now I am reading the xml into a temperary dataset, rs2, and trying to just copy the tables that I want, but I can't seem to get it to work. Is there 1) a better way to do what I want or 2) a way to copy tables into another or 3) will I have to read each row from the table into the other?

 

Thanks.
