Load/insert XML file larger than 32k

Hello,
we have faced problems in inserting/loading large (larger than 32k) XML files into XML columns.
My questions:
1) How to transfer this file to host and achieve this XML file remains unchanged?
2) Can anyone tell me what is recommended procedure for such large XMLs - using LOAD utility, INSERT statement, using any other tool...?

Thanks in advance,
Ivana
