Hi ,
I think one approach could be that you upload the XML file in BLOB column of a table ,it may be a custom table using the OAMessageFileUploadBean to upload the xml file ,then you have to select the same file from database and need to create a method inside the controller to read the contents of xml.
the below links can be usefull in terms to guide how to read xml in java
