I wat to perform some performance measurements on an XML database. FOr
this reason i need some huge XML sample data. The data should be not
too structured and a lot of reasonable queries should make sense.
Any idea, where i can get this data ??

Make it yourself. That way you can control the size and the
distribution of certain features. If this process is automated, then
you can easily run tests over and over with different parameters.
It's often useful (but rarely done) to test, not just that "it works",
but to test for sensitivity to different sorts of load. Does
performance change with many small items, or with few large items ?
Does sorted/unsorted input data make a difference ?
Another source of "real world" data in a large corporate is to connect
to something like an LDAP server and use that. I've also done much of
my own testing with lists of endangered species form the WCMC. You may
also find the W3C site useful, particularly the RDF test cases (not
large, but they do demonstrate many obscure conditions).

You might get some RSS feed. RSS is a form used by several news servers to
distribute news. So by definition, there is not much structure, but you can
make reasonable queries, like what happed (some terrorist act), what was the
score (some soccer game) etc.

I'm not sure what you mean by "huge", but there is a good amount of
data that might be intersting to query at: http://www.ibiblio.org/xml/examples/shakespeare/

Why don't you generate them ?

You might get some RSS feed.
But RSS - by definition - is not "huge XML data".

But I got two out of third: it is not too structured and there can be
reasonable queries !

Good idea. There are 5 major XML DB Benchmark efforts. Some include data
generators. See:

Some benchmarks and performance issues are also covered in the book I
helped edit:

Hello,
I need to allow an end user to upload video files on a server and in the
same time to put the file name and a few infos in a database. It must be
very simple for the end user, and uploading with a browser in a form
would be perfect since it allows to upload and fill a form in the same
time.
I'll have full control of the server (no max_size problem etc). The end
user connexion is ADSL, the server is on a 100mb internet connexion.
