[fpc-pascal] Patch: new XML export for FCL-DB ready for inclusion, issue 19790 - includes Delphi Clientdataset

[Reinier Olislagers]

Update: includes first stab at Delphi Clientdataset. Please test with
various datatypes as I haven't been able to map all of them...

Hi list (& Michael Van Canneyt ;),

Earlier I announced I was writing another XML export module for FCL-DB.

After some interesting hours with Excel, Access, .Net and FreePascal,
and thanks to Ludo Brands for testing and bugfixes, it seems the work is
done.

What is it: an FCL-DB export module that can export in various Unicode
XML formats: Access/SQL Server, ADO.Net, Excel and Delphi ClientDataset.


Suggestions for additional XML export formats are welcome.

Is it tested: yep: export and import on Access XP, import by ADO.Net,
import on Excel XP. Earlier versions of the code were tested with import
on Access 2010.
(Delphi Clientdataset needs to be tested though)

The code comes with some simple tests (basically testing if the various
export formats actually finish without error) and a readme.

I think it is stable enough to include in FPC 2.5.1 for more wide scale
use and testing.

I've uploaded it to bug 19790:
files:
20110727Final_XMLXSDExport_Code.zip: the code, patch for fpc makefile
I've annotated the code with Lazarus todo entries to indicate possible
improvements/tests.
20110727Final_XMLXSDExport_Tests.zip: the test code. Note: I haven't patched
any makefiles, don't know if that's necessary

Could an administrator remove the rest of the files as they are older,
superfluous and will confuse users? Thanks.

Hope it can be applied, of course I'm available for any necessary
changes/improvements,

Thanks for all the help,
Reinier
