XML tree-view as a database frontend in Rev?

[Toma Tasovac]

I have a highly structured mySQL database which I am using as a content 
depository for a dictionary project. The db is designed in such a way 
that each dictionary entry follows the TEI XML guidelines.  I would 
like to build an XML tree view of database records and allow the user 
to edit the records in the tree view (similar to the way it's done in 
the example stack xmltree-view which comes with Rev).

So far, I have learned how to query, select, display and edit mySQL 
records in Rev, but I am having difficulties making the jump toward XML 
in Rev.  What would be the right place to start when trying to 
implement the Rev xml tree parsing abilities as a database frontend?  
In other words, what would be the most straightforward way of telling 
Rev. to display a set of db records in the xml tree view?  And then 
telling the database to update the records based on the changes made in 
the xml tree view.

Any pointers would be greatly appreciated.

All best,
Toma
