Best approach for comparing 2 XML files (Before & After) for specific changes?

I have a Database that I update on a weekly basis that creates XML files that I would like to compa开发者_运维技巧re after making changes.

The database is set up with 150 Pages which each contain 50 tables. These tables contain an identifier which is sometimes moved to different tables or different pages, or removed all together.

I'm hoping to find a way to compare the 2 XML files from before I make my changes and after and identify

when an ID moved from one page, table to another when an ID is changed when an ID is removed or when other attributes for the table are changed

and output the changes to a file or a SQL database

For Example: Page 3, Table 2 was changed from ID 3452 to ID 2316 Page 3, Table 7 was moved to Page 3, Table 1 Page 3, Table 8 was deleted

I'm guessing I need a way to query each page, table coordinate for changes.

I've been hunting google all afternoon but I'm not really sure how to phrase what I am looking for and I think it may be hindering my search attempts.
