XML Import Export (Data Mapper)

We have an application and the database for it is user customisable.  We need to be able to import and export data to various 3rd parties in their specific format.

In essance what we need is for a user to be able to select a .xml or xsd file and then map their fields to that document.
We can then store this "Template" in our database, and the next time they want to import or export an xml file that can just select a the file an a "Template" and it will do the rest for them.

I hope this is clear.

Any clues as to how I could achive this would be a great help.

Create a view on your DB with the columns that can be selected.

create this table

    ColumnId (PK)

place a row in it for each of the columns in the view

Create these tables

    TemplateId (PK)

    TemplateId (FK to  tblTemplate)
    ColumnId (FK to  tblColumn)

Put a textbox and multi-select listbox on a form and populate it with the contents of tblColumn. Allow your customers to enter the name of a template in the textbox and select fields from the listbox. When they save create a new row in tblTemplate and loop through the listbox getting the keys to create rows for tblTemplateColumn.

In anotherform allow the user to select a previously created template. Create a stored procedure to create a dynamic SQL Select statement to get data from the initial view.

Sorry this is sketchy but that's the nest I can do with the information provided.

Now back to work.

Thanks for the response fds_fatboy.

What I need to know is how to do the XML part.  

How to read a xsd/dtd/xml file into a format that could be turned in to a template.
How to then turn that template into an xml file (that matches the dtd/xsd if provided).
How to read a imported xml file against the template and hence map the fields to our database

I can't help thinking there must be an SDK or something out there that does this allready as I imagine that this is a fairly common request.
Well there's this one from microsoft.


It's very easy to use with VB. Also, if you are using dotNet check out ADO.Net - loads of XML in there - What DB are you using?
Well I think we were on the way to a solution but then sajohnstone just buggered off. Looking at his/her profile, 1 question/1 comment not bothering to answer questions. I think he/she is gone for good.

Never mind.
