XML - Part Two - The Export

This is the second XML article in this mini series.  Once you have created the script library in your database (Part One), you can create the first of the two agents.

The agent below allows a user to export the selected documents as XML.  This creates an XML tree of "Documents", with each "Document" being a node.  This code fixes the file destination to "C:\Temp\Document.xml", so you will have to change this to fit your requirements.

I use a view to handle the field names to export, as I do not want to export every field.  My field configuration will be the subject of a further post.  For now, think of it as a list of field names where there is one document per field.
