XML Performance in validating Schema

[faisal mahmood]

Hi,
I was looking for a very fast free XML parser for validating throusands XML documents against a single fixed Schema. I was wondering if the parser load the DTDs or Schemas every time they validate an XML file. If I have thousands of files there will be unnecessary overhead.
If there is a solution let me know.

Faisail,
The time required to load a Schema or a DTD definition is insignificant when compared to the time spent in parsing and validating the document instances against the Schema/DTD.
