Hi,
Does anyone have any ideas as to why the LoadXml statement in the
following code takes so 8-10 seconds on a 2.4 GHz machine? Just seems to
me that it should be a great deal faster. Also if there is a faster way of
doing it, please let me know.

Thanks,
Dave

I am not familiar with .NET + XML classes, but maybe .NET tries to get
the dtd from the internet.
 
Hi Herfried,

If I did know I had told it,

But it is not a standard Net dataset scheme I thought .

Thanks both of you for pointing this out. You are definately correct that
going out to the dtd was slowing it down. I ended up downloading the dtd
and all associated files to my server and redirected the Xml to point to my
server instead. The speed shot through the roof. Thanks to both of you for
your help.

Thanks Again,
David J. Ricker II
