Chris,

Your scenario involves unknown data and unknown schemas.  If the sources of your inputs are not trusted, you are opening yourself to a wide range of potential problems (such as DoS attacks).

Hi all,

I've got a java process that needs to continously validate xml documents according to the w3c schemas they indicate in their xsd:schemaLocations.  The documents arrive at a high rate and must be processed as quickly as possible.  The exact schemas they employ are not known ahead of time and there may be several of them required to validate each document.

My question is, what library/libraries are appropriate in this situation and how do I tell them to only load the required schema(s) only once?  Any advice?

Thanks,
Chris
