Indexing Using XML Message

[Tod]

I have a local data store containing a host of different document types. 
 This data store is separate from a remote Solr install making 
streaming not an option.  Instead I'd like to generate an XML file that 
contains all of the documents including content and metadata.

What would be the most appropriate way to accomplish this?  I could use 
the Tika CLI to generate XML but I'm not sure it would work or that its 
the most efficient way to handle things.  Can anyone offer some suggestions?


Thanks - Tod
