Re: [xml] Performance xmlXPathEvalExpression

["Shirazi Babak" <Babak Shirazi datasystems at>]

Sorry I did not want to be impolite. The use of another parser was an idea.

I find your text absolutely superfluous.

Thank you

  I guess it's time at this point that you look at your environment 
and do the debug on your system ! There is only so much we can do for you and only getting negative feedback 
for the free tool and support you have been given starts to get close to impolite.
  Would you mind checking if Microsoft support is as nice and cheap, I think you need a small reality check 
at this point, I really really didn't like your message about MSXML earlier today. Of course you can use 
something else, trying to use it to get more attention than you deserve is really an unpleasant tactic ! Your 
system is swapping. If you don't understand or don't want to look at it use something else. If you can do a 
bit of analysis instead of complaining you could for example realize that there are streaming parsing APIs in 
libxml2 and that data extraction that way could be done in very little 
memory and way more efficiently than with XPath. But if that means we need to baby step you all the way until 
you manage to get 'something' we have no idea about to work, really please consider alternatives.

  thank you,

Daniel
