Several.  It depends on platform to some extent.  You could try
libxml, though
    http://www.xmlsoft.org/

Another approach might be to use XInclude, and make a single XML
document that includes all the others -- a tradeoff between memory
and speed.

Another might be to remember which documents were valid, e.g. by
creating a file to indicate validity for each, and using a tool
such as "make" to validate only those files that have changed
since they were last checked.

The Google.com approach might be to use 1200 PCs, each validating
one file :-)
