Upload XML file data into internal table

Question

Hi,
I need help from you.
I am uploading XML file from Application server.
1.In application server under directory it may have several XML files and i need to upload all the XML files  when we gave only directory name. So, what is the function module for that logic . If possible code also.
2.Once we get the files into some internal table we need to upload data from that files to internal table.
So what is the logic for that , if possible code also.
I am giving sample directory:    
For example in this directory assume 3 xml files are there.
I need to upload those files and data from that in to internal table.
Thanks & Regards
VSR
