Xerces Validation with XML Schema - runtime

P: n/a
Hello,

I built a XSD File with the tool XML-Spy from Altova. My XML file
consists of about 5000 elements. If I use the validate button in
XML-Spy, the validation process takes about 8 seconds. But if I use
Xerces-J2 to validate my XML File it takes about 90 seconds (xerces-c
takes about 85 sec).

Does anybody know, why xerces is that slow resp. why XML Spy is that
fast?
And could you give me some hints how to speed up the validation with
xerces?

Thanks and best redargs,
mrc-1

Hi,

Now I localized the runtime problem:
In my schema I limited the maximun occurrence of an element with
maxOcc=8048.
The runtime is independent from the amount of the elements in the XML
File.

If I set maxOcc=unbounded, the validation process takes about 500ms.

Is there any possibility to decrease the runtime (I have to limit the
occurence with maxOcc=8048)? Any special parser
configurations/properties etc.?
