I suspect that an off-the-shelf parser like Xerces is quite
fast enough if your application invokes it intelligently. You might find parsers
that are 20% faster than that, but I think the order-of-magnitude improvement
will come by changing your application architecture: in particular, change the
Xerces has a fairly high start-up cost so it's worth
reusing the parser for multiple documents. However, that's more of a factor when
your files are 200 bytes rather than 50K bytes.
We need a very fast validating XML
parser and was wondering if anyone has any suggestions? Our project involves
one main XML file with about 1200 supporting XML files (each about 50KB or
less). Our current environment calls on a java script to validate each file
against the DTD, but it is painfully slow to process the complete project. We
suspect that that the overhead in creating the java environment each time the
script is called is slowing down the process. I have searched (and am still
searching) the web for a good alternative. Any
