 * History:
 * $Log: ocontactaccessbackend_xml.cpp,v $
 * Revision 1.9  2003/09/22 14:31:16  eilers
 * Added first experimental incarnation of sql-backend for addressbook.
 * Some modifications to be able to compile the todo sql-backend.
 * A lot of changes fill follow...
 *
 * Revision 1.8  2003/08/30 15:28:26  eilers
 * Removed some unimportant debug output which causes slow down..
 *
 * Revision 1.7  2003/08/01 12:30:16  eilers
 * Merging changes from BRANCH_1_0 to HEAD
 *
 * Revision 1.6  2003/07/07 16:19:47  eilers
 * Fixing serious bug in hasQuerySettings()
 *
 * Revision 1.5  2003/04/13 18:07:10  zecke
 * More API doc
 * QString -> const QString&
 * QString = 0l -> QString::null
 *
 * Revision 1.4  2003/03/21 14:32:54  mickeyl
 * g++ compliance fix: default arguments belong into the declaration, but not the definition
 *
 * Revision 1.3  2003/03/21 12:26:28  eilers
 * Fixing small bug: If we search a birthday from today to today, it returned
 * every contact ..
 *
 * Revision 1.2  2003/03/21 10:33:09  eilers
 * Merged speed optimized xml backend for contacts to main.
 * Added QDateTime to querybyexample. For instance, it is now possible to get
 * all Birthdays/Anniversaries between two dates. This should be used
 * to show all birthdays in the datebook..
 * This change is sourcecode backward compatible but you have to upgrade
 * the binaries for today-addressbook.
 *
 * Revision 1.1.2.2  2003/02/11 12:17:28  eilers
 * Speed optimization. Removed the sequential search loops.
 *
 * Revision 1.1.2.1  2003/02/10 15:31:38  eilers
 * Writing offsets to debug output..
 *
 * Revision 1.1  2003/02/09 15:05:01  eilers
 * Nothing happened.. Just some cleanup before I will start..
 *
 * Revision 1.12  2003/01/03 16:58:03  eilers
 * Reenable debug output
 *
 * Revision 1.11  2003/01/03 12:31:28  eilers
 * Bugfix for calculating data diffs..
 *
 * Revision 1.10  2003/01/02 14:27:12  eilers
 * Improved query by example: Search by date is possible.. First step
 * for a today plugin for birthdays..
 *
 * Revision 1.9  2002/12/08 12:48:57  eilers
 * Moved journal-enum from ocontact into i the xml-backend..
 *
 * Revision 1.8  2002/11/14 17:04:24  eilers
 * Sorting will now work if fullname is identical on some entries
 *
 * Revision 1.7  2002/11/13 15:02:46  eilers
 * Small Bug in sorted fixed
 *
 * Revision 1.6  2002/11/13 14:14:51  eilers
 * Added sorted for Contacts..
 *
 * Revision 1.5  2002/11/01 15:10:42  eilers
 * Added regExp-search in database for all fields in a contact.
 *
 * Revision 1.4  2002/10/16 10:52:40  eilers
 * Added some docu to the interface and now using the cache infrastucture by zecke.. :)
 *
 * Revision 1.3  2002/10/14 16:21:54  eilers
 * Some minor interface updates
 *
 * Revision 1.2  2002/10/07 17:34:24  eilers
 * added OBackendFactory for advanced backend access
 *
 * Revision 1.1  2002/09/27 17:11:44  eilers
 * Added API for accessing the Contact-Database ! It is compiling, but
 * please do not expect that anything is working !
 * I will debug that stuff in the next time ..
 * Please read README_COMPILE for compiling !
