Re: [xml] Multiple users for same XML file...

[Gavin Sherry <swm linuxworld com au>]

This is a locking issue, unrelated to XML. There are lots of Web sites
explaining file system level locking. Also see flock(2).

If you want to operate on nodes within a document, you have bigger
problems. I would recommend you move to a relation data model for the
storage of your configuration.
