parallel updates to an xml

2
Hi

I have to create a log file in xml format. Could anyone please suggest how the following can be achieved:

1. There are many parallel threads. How can we ensure the integrity of the xml file when parallel threads are trying to write to the same log file i.e. the structure of the xml should not get spoiled. Each thread should add/delete only those xml tags that it should

2. Since many parallel threads are updating the same xml file, how can we ensure that the system performance does not become too bad.

Thanks

"how can you ensure integrity:
You cannot keep integrity of the XML without loosing performance

"how can you ensire performance":
Make it a flat-file where you're logging to. Others, like apache and mysql, do the same, and not for a bad reason.

Thanks for the reply Luuk. Could you advise if it is possible to create a log file in some custom xml format using Log4J or SL4J
