if you are filtering a data feed and discarding most of the incoming data, then
a streaming processor is clearly the right approach.</FONT></SPAN></DIV>

tool<BR></FONT><BR></DIV>
<DIV></DIV>Hello guys,<BR><BR>I am looking for good XQuery tool. But there are
some requirements: XML file may exceed the size of 5-8 GB.<BR>The tools i am
using now, like Saxon or Altova XML Spy, can't really handle such
file.<BR><BR>I have hound database engine MonetDB, for fast xqueries on big
data sets. But it seems to be still in developing phase (and a lot of things
are missing, like connectors).<BR><BR>Do you have any
suggestions?<BR><BR><BR>Thanks,<BR>Michal<BR></BLOCKQUOTE></BODY></HTML>
